Here is what I have: k = open('./' + basefile + '.key', 'r') k1 = k.read() k.close() my_key = binascii.a2b_hex(k1) When I print k1, it is as expected: 81e3d6df Here is the error message: Traceback...

How would I do this? Do I need some kind of wrapper to hold of of the python test cases together? How do I get Selenium Grid to run a collectio...
How can I replace the contents of strings with #'s in Python? Assume no comments, no multiple lines for one string. Like if there is a line in a python file: print 'Hello' + "her mom's shirt". This will be translated into: print '#####' + "###############". It's like a filter to deal with every line in a python file. ...

Let's say I have two data sets. I have a week-by-week tally of users who tried my service. trials = [2,2,2,8,8,4] And I have a week by week tally of trial users who signed up. conversions = [1,0,2,4,8,3] I can do it pretty quickly this way: conversion_rate = [] for n in range(len(trials)): conversion_rate.append(conversions[n]/...
Initially i thought to do something like: #EXIT CODES class ExitCode(object): (USERHOME_INVALID, \ USERHOME_CANNOT_WRITE, \ USERHOME_CANNOT_READ, \ BASHRC_INVALID) = range(-1, -5, -1) But than I've realized that I'll have to know exactly the total number of EXIT_CODES, so that I can pass it to the range() function. Let...
I want to detect whenever the selection of my gtk.TreeView changes and, when it does, to call a function w/ this information. The only way I've found to do it so far is to attach to all these signals: ... self.sitterView.connect("cursor-changed", self.selectionChanged) self.sitterView.connect("unselect-all", self.selectionChange...

Is there a way to send an interrupt to a python module when the user inputs something in the console? For example, if I'm running an infinite while loop, i can surround it with a try/except for KeyboardInterrupt and then do what I need to do in the except block. Is there a way to duplicate this functionality with any arbitrary input? Ei...
Not sure if this has a straightforward solution, but I want to write a function that shows a dialog (defined elsewhere in a class that inherits QDialog) and returns the user input when the user has finished interacting with the dialog. In other words, something similar to the QFileDialog::getOpenFileName static method, where a single lin...
