  • Go through a number of functions in Python

    - by Asaf
    I have an unknown number of functions in my python script (well, it is known, but not constant) that start with site_... I was wondering if there's a way to go through all of these functions in some main function that calls for them. something like: foreach function_that_has_site_ as coolfunc if coolfunc(blabla,yada) == true: return coolfunc(blabla,yada) so it would go through them all until it gets something that's true. thanks!

  • Backup of folder + database - Python

    - by RadiantHex
    Hi there, I feel like this is quite delicate, I have various folders whith projects I would like to backup into a zip/tar file, but would like to avoid backing up files such as pyc files and temporary files. I also have a Postgres db I need to backup. Any tips for running this operation as a python script? Also, would there be anyway to stop the process from hogging resources in the process? Help would be very much appreciated.

  • Counts of events grouped by date in python?

    - by Sologoub
    This is no doubt another noobish question, but I'll ask it anyways: I have a data set of events with exact datetime in UTC. I'd like to create a line chart showing total number of events by day (date) in the specified date range. Right now I can retrieve the total data set for the needed date range, but then I need to go through it and count up for each date. The app is running on google app engine and is using python. What is the best way to create a new data set showing date and corresponding counts (including if there were no events on that date) that I can then use to pass this info to a django template? Data set for this example looks like this: class Event(db.Model): event_name = db.StringProperty() doe = db.DateTimeProperty() dlu = db.DateTimeProperty() user = db.UserProperty() Ideally, I want something with date and count for that date. Thanks and please let me know if something else is needed to answer this question!

  • python `IN` module problem (FreeBSD)

    - by Shamanu4
    I'm trying to work with sockets and I have such problem In code example: setsockopt(socket.SOL_SOCKET,IN.SO_BINDTODEVICE,self.listen_address+'\0') I have error AttributeError: 'module' object has no attribute 'SO_BINDTODEVICE' On Linux machine this attribute is OK but on FreeBSD trere are no any SO_* attributes in module IN. What port should I install to resolve this problem on FreeBDS machine? Python versions on Linux tested: 2.5.4 and 2.6.4; on FreeBSD: 2.5.5 I can't find anything about this module in my book, and googling keyword IN looks like seamless ...

  • Customized command line parsing in Python

    - by Moshe
    I'm writing a shell for a project of mine, which by design parses commands that looks like this: COMMAND_NAME ARG1="Long Value" ARG2=123 [email protected] My problem is that Python's command line parsing libraries (getopt and optparse) forces me to use '-' or '--' in front of the arguments. This behavior doesn't match my requirements. Any ideas how can this be solved? Any existing library for this?

  • Accessing MySQL server via VPN in python

    - by user210481
    Hi I have a MySQL server that I need access through a VPN. I use MySQLdb package to access MySQL server in Python. When I can access the server without VPN, it works fine, but when I'm at certain locations, I need to connect through VPN. My computer is connected to the VPN and I can access the database through PHPMyAdmin, but MySQLdb gives me an error message: OperationalError: (2003, "Can't connect to MySQL server on 'MY_IP' (10061)") Any ideas on why it's not working? Thanks

  • Making Noise with Python

    - by Elliot
    I am trying to get python to make noise when certain things happen. Preferably, i would like to play music of some kind, however some kind of distinctive beeping would be sufficient, like an electronic timer going off. I have thus far only been able to make the system speaker chime using pywin32's Beep, however this simply does not have the volume for my application. Any ideas on how I can do this?

  • Splitting a list in python

    - by blob8108
    Hi, I'm writing a parser in Python. I've converted an input string into a list of tokens, such as: ['(', '2', '.', 'x', '.', '(', '3', '-', '1', ')', '+', '4', ')', '/', '3', '.', 'x', '^', '2'] I want to be able to split the list into multiple lists, like the str.split('+') function. But there doesn't seem to be a way to do my_list.split('+'). Any ideas? Thanks!

  • python how to find the median of a list

    - by user3450574
    I'm trying to write a function named median that takes a list as an input and returns the median value of the list. I'm working with Python 2.7.2 The list can be of any size and the numbers are not guaranteed to be in any particular order. If the list contains an even number of elements, the function should return the average of the middle two. This is the code I'm starting with: def median(list): print(median([7,12,3,1,6,9]))

  • Importing Python modules without installing - Sybase ASE

    - by Michael
    I need to use the Sybase Python module but our SA's won't install because it's not in the repo's. I've downloaded it and placed it on the box and would just like to 'import' or 'include' the module without installing it first. - Is this possible? From the looks of it (Sybase ASE) it needs some type of compilation before use. Is it possible for this type of work around?
