The collections are like a set in that order doesn't matter for the comparison. However, in my problem equal elements are significant. E.g. the collection of …  |
| | I'm interested in a generic event system for Python. I've searched the forum for similar topics, and I've searched the web for existing implementations. I haven't found exactly what I'm looking for. I'm familiar with the Observer pattern. However, my implementation and other implementations lack strong support for concurrency and … |
| | I know that certain functions will check the script's or module's current directory for the file if no path is specified. [code=PYTHON]open('test.txt')[/code] If that script is run and test.txt is in the same directory that will open the correct file. However, if I try to import that module it doesn't … |
| | I'm having a problem with 'os.path.getmtime'. I've been doing some research into generating '.pyc' files and I am able to retrieve the source modification time (in seconds) as recorded in the '.pyc' file. It is merely the second set of four bytes unpacked as a long integer. [code=Python] import random, … |
| | I've seen these in documentation, namely in the "importlib" documentation for Python 3.1, and I'm wondering what the difference is between a "universal newline" and a "standard newline", if any.

| | And I can't get anything I write to work. I'm so far off course I think I just need a working example of import hooks in action. I've looked for examples on the Internet, but they only show what looks like correct code. They never show that code in action. … |
| | I'm wondering if it's possible to change the border color of a tkinter entry widget border. I don't think it is, because no such option exists in relevant documentation. You can change the width, but that just results in the whitespace being recessed - creating a raised 3d border. If …  |

| | I always wondered how a programmer could efficiently generate a random number from a set* of numbers once and only once. I quickly realized the inefficient solution. Simply generate the number and if it equals one you have all ready generated then regenerate the number. Regenerating the number is a … |
| | Out of curiosity, how would you reverse a string's case in Python? Make uppercase characters lowercase and lowercase characters uppercase. Here's the function for the naive implementation. [CODE] #!/usr/bin/env python def flip_case(input_string): temp_list = list(input_string) for index, character in enumerate(temp_list): if character.islower(): temp_list[index] = character.upper() else: temp_list[index] = character.lower() output_string … |
