  • how to go back to first if statement if no choices are valid - python

    - by wondergoat77
    how can i have python move to the top of an if statement if nothing is satisfied correctly i have a basic if/else statement like this: print "pick a number, 1 or 2" a = int(raw_input("> ") if a == 1: print "this" if a == 2: print "that" else: print "you have made an invalid choice, try again." what i want is to prompt the user to make another choice for 'a' this if statement without them having to restart the entire program, but am very new to python and am having trouble finding the answer online anywhere.

  • MySQL: automatic rollback on transaction failure

    - by praksant
    Is there any way to set MySQL to rollback any transaction on first error/warning automatically? Now if everything goes well, it commits, but on failure it leaves transaction open and on another start of transaction it commits incomplete changes from failed transaction. (I'm executing queries from php, but i don't want to check in php for failure, as it would make more calls between mysql server and webserver.) Thank you

  • File encyption with Python

    - by Pinkie
    Is there a way to encrypt files (.zip, .doc, .exe, ... any type of file) with Python? I've looked at a bunch of crypto libraries for Python including pycrypto and ezpycrypto but as far as I see they only offer string encryption.

  • More nest Python nested dictionaries.

    - by clutch
    After reading http://stackoverflow.com/questions/635483/what-is-the-best-way-to-implement-nested-dictionaries-in-python why is it wrong to do: c = collections.defaultdict(collections.defaultdict(int)) in python? I would think this would work to produce {key:{key:1}} or am I thinking about it wrong?

  • Python 3.1 twitter post with installed library,

    - by Andrew
    I'd like to be able to post twitter messages from python 3.0. None of the twitter API I have looked at support python 3.1. Since the post proceedure only requires this : JSON: curl -u username:password -d status="your message here" http://api.twitter.com/1/statuses/update.json I was wondering if it is possible with the standard libraries to format this so a message could be sent. My head says it should be possible.

  • How can I get the last-modified time with python3 urllib?

    - by Daenyth
    I'm porting over a program of mine from python2 to python3, and I'm hitting the following error: AttributeError: 'HTTPMessage' object has no attribute 'getdate' Here's the code: conn = urllib.request.urlopen(fileslist, timeout=30) last_modified = conn.info().getdate('last-modified') This section worked under python 2.7, and so far I haven't been able to find out the correct method to get this information in python 3.1. The full context is an update method. It pulls new files from a server down to its local database, but only if the file on the server is newer than the local file. If there's a smarter way to achieve this functionality than just comparing local and remote file timestamps, then I'm open to that as well.

  • Creating SVG map from geometry stored in MySQL

    - by Barnabe
    I have a group of geometries stored in MySQl (as polygon and as well-known text) representing counties. I can build a table of geometries and color codes after querying some county data (say GDP per capita). What is the best way to export this as an SVG map? I cannot find any reference to SVG conversion in the MySQL documentation.

  • Using Python to add/remove Ubuntu login script items

    - by codebox_rob
    I have written a Python application and would like to give my users the option of having the app automatically launch itself when the user logs in. It is important that the user is able to toggle this option on/off from within the app itself, rather than having to manually edit login scripts, so this needs to be done from within the Python code rather than from a shell script. The app is deployed on Ubuntu Linux, any suggestions for the best way of doing this?

  • Python: Is there a way to reflectivly list all attributes of a class

    - by hhafez
    Given a class such as def MyClass text = "hello" number = 123 Is there a way in python to inspect MyClass an determine that it has the two attributes text and number. I can not use something like inspect.getSource(object) because the class I am to get it's attributes for are generate using SWIG (so they are hidden in .so :) ). So I am really looking for something equivalant to Java's [Class.getDeclardFields][1] Any help would be appreciated, otherwise I'll have to solve this problem with SWIG + JAVA instead of SWIG + Python.

  • Development Environment for Testing MySQL Replication

    - by Dave Morris
    Is there an easy way to setup an environment on one machine (or a VM) with MySQL replication? I would like to put together a proof of concept of MySQL replication with one Master write instance and two slave instances for reads. I can see doing it across 2 or 3 VMs running on my computer, but that would really bog down my system. I'd rather have everything running on the same VM. What's the best way to proof out scalability solutions like this in a local dev environment? Thanks for your help, Dave

  • MySQL 5.1 - logging CREATE/ALTER statements

    - by pako
    Is it possible to log CREATE / ALTER statements issued on a MySQL server? I heard that it could be done with a trigger, but I can't seem to find suitable code anywhere. I would like to log these statements to a table, preferably with the timestamp of when they were issued. Can someone provide me with a sample trigger that would enable me to accomplish this? I would like to log these statements so I can easily synchronize the changes with another MySQL server.

  • Python and displaying HTML

    - by Tyler Seymour
    I've gotten pretty comfortable with Python and now I'm looking to make a rudimentary web application. I was somewhat scared of Django and the other Python frameworks so I went caveman on it and decided to generate the HTML myself using another Python script. Maybe this is how you do it anyways - but I'm just figuring this stuff out. I'm really looking for a tip-off on, well, what to do next. My Python script PRINTS the HTML (is this even correct? I need it to be on a webpage!), but now what? Thanks for your continued support during my learning process. One day I will post answers! -Tyler Here's my code: from SearchPhone import SearchPhone phones = ["Iphone 3", "Iphone 4", "Iphone 5","Galaxy s3", "Galaxy s2", "LG Lucid", "LG Esteem", "HTC One S", "Droid 4", "Droid RAZR MAXX", "HTC EVO", "Galaxy Nexus", "LG Optimus 2", "LG Ignite", "Galaxy Note", "HTC Amaze", "HTC Rezound", "HTC Vivid", "HTC Rhyme", "Motorola Photon", "Motorola Milestone", "myTouch slide", "HTC Status", "Droid 3", "HTC Evo 3d", "HTC Wildfire", "LG Optimus 3d", "HTC ThunderBolt", "Incredible 2", "Kyocera Echo", "Galaxy S 4g", "HTC Inspire", "LG Optimus 2x", "Samsung Gem", "HTC Evo Shift", "Nexus S", "LG Axis", "Droid 2", "G2", "Droid x", "Droid Incredible" ] print """<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>table of phones</title> </head> <body> </body> </html> """ #table print '<table width="100%" border="1">' for x in phones: y = SearchPhone(x) print "\t<tr>" print "\t\t<td>" + str(y[0]) + "</td>" print "\t\t<td>" + str(y[1]) + "</td>" print "\t\t<td>" + str(y[2]) + "</td>" print "\t\t<td>" + str(y[3]) + "</td>" print "\t\t<td>" + str(y[4]) + "</td>" print "\t</tr>" print "</table>
