  • Multiple Context menus in PyQt based on mouse location

    - by Nader
    I have a window with multiple tables using QTableWidget (PyQt). I created a popup menu using the right click mouse and it works fine. However, I need to create different popup menu based on which table the mouse is hovering over at the time the right mouse is clicked. How can I get the mouse to tell me which table it is hovering over? or, put in another way, how to implement a method so as to have a specific context menu based on mouse location? I am using Python and PyQt. My popup menu is developed similar to this code (PedroMorgan answer from Qt and context menu): class Foo( QtGui.QWidget ): def __init__(self): QtGui.QWidget.__init__(self, None) # Toolbar toolbar = QtGui.QToolBar() # Actions self.actionAdd = toolbar.addAction("New", self.on_action_add) self.actionEdit = toolbar.addAction("Edit", self.on_action_edit) self.actionDelete = toolbar.addAction("Delete", self.on_action_delete) # Tree self.tree = QtGui.QTreeView() self.tree.setContextMenuPolicy( Qt.CustomContextMenu ) self.connect(self.tree, QtCore.SIGNAL('customContextMenuRequested(const QPoint&)'), self.on_context_menu) # Popup Menu self.popMenu = QtGui.QMenu( self ) self.popMenu.addAction( self.actionEdit ) self.popMenu.addAction( self.actionDelete ) self.popMenu.addSeparator() self.popMenu.addAction( self.actionAdd ) def on_context_menu(self, point): self.popMenu.exec_( self.tree.mapToGlobal(point) )

  • Command-line input causes SyntaxError

    - by coson
    Good Day, I have a simple Python question that I'm having brain freeze on. This code snippet works. But when I substitue "258 494-3929" with phoneNumber, I get the following error below: # Compare phone number phone_pattern = '^\d{3} ?\d{3}-\d{4}$' # phoneNumber = str(input("Please enter a phone number: ")) if re.search(phone_pattern, "258 494-3929"): print "Pattern matches" else: print "Pattern doesn't match!" ####################################################### Pattern does not match Please enter a phone number: 258 494-3929 Traceback (most recent call last): File "pattern_match.py", line 16, in <module> phoneNumber = str(input("Please enter a phone number: ")) File "<string>", line 1 258 494-3929 ^ SyntaxError: invalid syntax C:\Users\Developer\Documents\PythonDemo> By the way, I did import re and tried using rstrip in case of the \n What else could I be missing? Thanks in advance.

  • Printing to STDOUT and log file while removing ANSI color codes

    - by Arrieta
    I have the following functions for colorizing my screen messages: def error(string): return '\033[31;1m' + string + '\033[0m' def standout(string): return '\033[34;1m' + string + '\033[0m' I use them as follows: print error('There was a problem with the program') print "This is normal " + standout("and this stands out") I want to log the output to a file (in addition to STDOUT) WITHOUT the ANSI color codes, hopefully without having to add a second "logging" line to each print statement. The reason is that if you simply python program.py > out then the file out will have the ANSI color codes, which look terrible if you open in a plain text editor. Any advice?

  • how can I make pip/setuptools understand that my package is in ./src?

    - by Giacomo Lacava
    I have a library with a layout like this in Github: README setup.py src/ somelibrary.py Note: I cannot change the layout, but I can change setup.py. I want to be able to reference this library from requirements.txt, so that people can do pip install -r requirements.txt and have it installed automagically. So I add a line like this into requirements: -e git+http://blablabla/blabla#egg=somelibrary This will clone the repository under ./src/somelibrary and then run setup.py develop on it, which will just add a link to ./src/somelibrary under site-packages. Unfortunately, because the library is actually under ./src/somelibrary/src, it seems like python can't see the library correctly. What am I missing? I guess it must be a setup.py option I'm not using correctly.

  • Django how to handle # in variable name.

    - by Jack
    I've got a dictionary in python which is assigned as a template variable. One of the keys is named "#text" but when i try to access it using {{ artist.image.3."#text"}} I get an error which is File "/home/jack/Desktop/test/appengine/lib/django/django/template/__init__.py", line 558, in __init__ raise TemplateSyntaxError, "Could not parse the remainder: %s" % token[upto:] TemplateSyntaxError: Could not parse the remainder: "#text" So how can I use this in the template? I've tried putting quotes around it but to no avail. I'd like to not modify the dictionary if possible, but if its easy enough to do then I guess its okay. Thanks

  • From interpeted to native code: "dynamic" languages compiler support

    - by Daniel
    First, I am aware that dynamic languages is a term used mainly by a vendor; I am using it just to have a container word to include languages like Perl (a favorite of mine), Python, Tcl, Ruby, PHP and so on. They are interpreted but I am interested here to refer to languages featuring strong capability to support the programmer efficiency and the support for typical constructs of modern interpreted languages My question is: there are dynamic languages can be compiled efficiently in native executable code - typically for Windows platforms? Which ones? Maybe using some third part ad-hoc tools? I am not talking about huge executables carrying with them a full interpreter or some similar tricks nor some smart module able to include its own dependances or some required modules, but a honest, straight, standard, solid executable code. If not, there is some technical reason inhibiting the availability of such a best-of-both-world feature? Thanks! Daniel

  • SQLAlchemy automatically converts str to unicode on commit

    - by Victor Stanciu
    Hello, When inserting an object into a database with SQLAlchemy, all it's properties that correspond to String() columns are automatically transformed from <type 'str'> to <type 'unicode'>. Is there a way to prevent this behavior? Here is the code: from sqlalchemy import create_engine, Table, Column, Integer, String, MetaData from sqlalchemy.orm import mapper, sessionmaker engine = create_engine('sqlite:///:memory:', echo=False) metadata = MetaData() table = Table('projects', metadata, Column('id', Integer, primary_key=True), Column('name', String(50)) ) class Project(object): def __init__(self, name): self.name = name mapper(Project, table) metadata.create_all(engine) session = sessionmaker(bind=engine)() project = Project("Lorem ipsum") print(type(project.name)) session.add(project) session.commit() print(type(project.name)) And here is the output: <type 'str'> <type 'unicode'> I know I should probably just work with unicode, but this would involve digging through some third-party code and I don't have the Python skills for that yet :)

  • SQLAlchemy custom sorting algorithms when using SQL indexes

    - by David M
    Is it possible to write custom collation functions with indexes in SQLAlchemy? SQLite for example allows specifying the sorting function at a C level as sqlite3_create_collation(). An implementation of some of the Unicode collation algorithm has been provided by James Tauber here, which for example sorts all the "a"'s close together whether they have accents on them or not. Other examples of why this might be useful is for different alphabet orders (languages other than English) and sorting numeric values (sorting 10 after 9 rather than codepoint order.) Is this possible in SQLAlchemy? If not, is it supported by the pysqlite3 or MySQLdb modules, or for any other SQL database modules supported by python for that matter? Any information would be greatly appreciated.

  • Component Creation How-to

    - by Larry Lewis
    I want to create a component that will allow me to install other components, modules, and plugins that i personally use all the time. I will need to be able to change these modules, components, and plugins at anytime but updating the components and etc.. that i use and be able to add more plugins and etc as well. I would like this Component because it takes too much time to install them all individually and on multiple sites as a web designer. I also would need to have some instruction on how to add subtract plugins, modules, components, and etc. I am ok with not a total integration i would like to be able to just host the install file on my server with a link to my server where the file is located. If anyone can help with this please do.

  • In Django, I want to insert a database record by sending myself an email?

    - by littlejim84
    Hello. I'm looking into a possible feature for my little to-do application... I like the idea that I can send an email to a particular email address, containing a to-do task I need to complete, and this will be read by my web application and be put in the database... So, when I come to log into my application, the to-do task I emailed will be there as a entry in the app. Is this possible? I have a slice with SliceHost (basically a dedicated server) so I have total control on what to install etc. I'm using Python/Django/MySQL for this. Any ideas on what steps to take to make this happen?

  • Will being self-taught limit me?

    - by Isaiah
    I'm 21 and am pretty efficient in html/css, python, and javascript. I also know my way around lisp languages and enjoy programing in them. My problem is that I'm extremely self-taught and not quite confident that I could land a job programing, but I really need a job soon as I've just become a father. I haven't even created a resume yet because I'm not really sure what to put on it except my lone experience. So I wanted to ask, will being primarily self-taught with some experience on small projects I've done for a few clients limit me too much? I mean I know I need some kind of education so I've enrolled part time in a community college to work on a degree in computer science, but it's years till then. And if it will limit me a lot, what kind of skills would be good to work on to make my chances any better? Thank You

  • How do I customize what a third party MSM does?

    - by sqlrob
    I'm trying to convert a project in Visual Studio 2008 from static linking of the CRT to dynamic linking. This was easy enough, and I added the CRT MSM and policy MSM to my Wix file with no problems. I am not that happy with the MSI that is output though, it is much larger than what I expected. Looking at the MSI with Orca shows three copies of the CRT DLLs that I need. From looking at the conditions, one of the sets is used for pre-XP installs. Since the system requirements are XP and later, how do I remove this component without touching the original MSM? This needs to be done in an automated build, so Orca isn't a possible solution. Plus, when I tried it with Orca, the filesize remained the same after deleting the File and Component rows. And somewhat related, how do I set the permanent attribute in the components that remain?

  • Problem building PyGTK on CentOS

    - by Marcelo Cantos
    I am trying to build PyGTK on CentOS for a non-standard Python (2.6, vs the out-of-the-box 2.4). It requires that I first build pygobject. pygobject-2.18.0 fails at the configure step. The error messages is as follows: checking for GLIB - version >= 2.14.0... no *** Could not run GLIB test program, checking why... *** The test program failed to compile or link. See the file config.log for the *** exact error that occured. This usually means GLIB is incorrectly installed. configure: error: maybe you want the pygobject-2-4 branch? I have downloaded, built and successfully installed glib. The config.log file contains the following output: configure:6893: gcc -E conftest.c conftest.c:13:28: error: ac_nonexistent.h: No such file or directory What am I doing wrong?

  • Any implementations of graph st-ordering or ear-decomposition?

    - by chang
    I'm in the search for an implementation of an ear-decomposition algorithm (http://www.ics.uci.edu/~eppstein/junkyard/euler/ear.html). I examined networkx and didn't find one. Although the algorithm layout is vaguely in my mind, I'd like to see some reference implementation, too. I'm aware of Ulrik Brandes publication on a linear time Eager st-ordering algorithm, which results in an ear decomposition as a side product, if I understand correctly (it even includes pseudocode, which I'm trying to base my implementation on). Side problem: First step could be an st-ordering of a graph. Are there any implementations for st-ordering algorithms you know? Thanks for your input. I'd really like to contribute e.g. to networkx by implementing the ear-decomposition algorithm in python.

  • Loop over a file and write the next line if a condition is met

    - by 111078384259264152964
    Having a hard time fixing this or finding any good hints about it. I'm trying to loop over one file, modify each line slightly, and then loop over a different file. If the line in the second file starts with the line from the first then the following line in the second file should be written to a third file. !/usr/bin/env python with open('ids.txt', 'rU') as f: with open('seqres.txt', 'rU') as g: for id in f: id=id.lower()[0:4]+'_'+id[4] with open(id + '.fasta', 'w') as h: for line in g: if line.startswith(''+ id): h.write(g.next()) All the correct files appear, but they are empty. Yes, I am sure the if has true cases. :-) "seqres.txt" has lines with an ID number in a certain format, each followed by a line with data. The "ids.txt" has lines with the ID numbers of interest in a different format. I want each line of data with an interesting ID number in its own file. Thanks a million to anyone with a little advice!

  • Best data-structure to use for two ended sorted list

    - by fmark
    I need a collection data-structure that can do the following: Be sorted Allow me to quickly pop values off the front and back of the list Remain sorted after I insert a new value Allow a user-specified comparison function, as I will be storing tuples and want to sort on a particular value Thread-safety is not required Optionally allow efficient haskey() lookups (I'm happy to maintain a separate hash-table for this though) My thoughts at this stage are that I need a priority queue and a hash table, although I don't know if I can quickly pop values off both ends of a priority queue. I'm interested in performance for a moderate number of items (I would estimate less than 200,000). Another possibility is simply maintaining an OrderedDictionary and doing an insertion sort it every-time I add more data to it. Furthermore, are there any particular implementations in Python. I would really like to avoid writing this code myself.

  • Database query optimization

    - by hdx
    Ok my Giant friends once again I seek a little space in your shoulders :P Here is the issue, I have a python script that is fixing some database issues but it is taking way too long, the main update statement is this: cursor.execute("UPDATE jiveuser SET username = '%s' WHERE userid = %d" % (newName,userId)) That is getting called about 9500 times with different newName and userid pairs... Any suggestions on how to speed up the process? Maybe somehow a way where I can do all updates with just one query? Any help will be much appreciated! PS: Postgres is the db being used.

  • How do I get the position of a result in the list after an order_by?

    - by Bob Bob
    I'm trying to find an efficient way to find the rank of an object in the database related to it's score. My naive solution looks like this: rank = 0 for q in Model.objects.all().order_by('score'): if q.name == 'searching_for_this' return rank rank += 1 It should be possible to get the database to do the filtering, using order_by: Model.objects.all().order_by('score').filter(name='searching_for_this') But there doesn't seem to be a way to retrieve the index for the order_by step after the filter. Is there a better way to do this? (Using python/django and/or raw SQL.) My next thought is to pre-compute ranks on insert but that seems messy.

  • Importing Sqlite data into Google App Engine

    - by Keck
    I have a relatively extensive sqlite database that I'd like to import into my Google App Engine python app. I've created my models using the appengine API which are close, but not quite identical to the existing schema. I've written an import script to load the data from sqlite and create/save new appengine objects, but the appengine environment blocks me from accessing the sqlite library. This script is only to be run on my local app engine instance, and from there I hope to push the data to google. Am I approaching this problem the wrong way, or is there a way to import the sqlite library while running in the local instance's environment?
