Remove Filter  | There is a security technique known as code signing. It basically generates a certificate for your code. This certificate first certifies the author of the code. Second, it has a value generated from the code. This value is unique to that code. If any changes are made to the code, … |
| | I had been wanting to write an IRC bot with asynchronous IO for a while. My bot responds to pings, but can be extended by defining functions and registering them to get called when the bot receives certain commands. My bot uses the RFC 1459 USER command and parameters, but … |
| | I am doing some hobby coding regarding neural networks, and I was wondering if this is a correct and good use of abstract base classes or not. [code=PYTHON]import abc import collections import math import weakref class AbstractNeuron(metaclass=abc.ABCMeta): def __init__(self, weights, f=math.tanh, bias=1, biasWeight=0): self.weights = weights self.f = f self.bias …  |
| | I'm working on a project where I would like to compare collections of words, but I have additional constraints I need to account for. 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 … |
| | U.S. Military Weapons Inscribed With Secret 'Jesus' Bible Codes Pentagon Supplier for Rifle Sights Says It Has 'Always' Added New Testament References [URL="http://abcnews.go.com/Blotter/us-military-weapons-inscribed-secret-jesus-bible-codes/story?id=9575794"]http://abcnews.go.com/Blotter/us-military-weapons-inscribed-secret-jesus-bible-codes/story?id=9575794[/URL] I saw this. I think this is wrong.  |
| | 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 was wondering if anyone knows of any resources about building a custom importer. I've found this: [url]http://www.doughellmann.com/PyMOTW/sys/imports.html[/url]. I am also aware of PEP 302 and PEP 369 and imp and importlib. Are there any other resources I might need? |
| | 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. I know it has to do with the byte sequence that is used to represent newlines, and I think universal …  |
| | I'm using the code module to add an interactive interpreter to an object. This object has an interact method that when called creates an interactive interpreter with the object's dictionary as the namespace for the interpreter. When done interacting with the object, I want the "exit" function to return execution … |
| | I'm just wondering if it is possible to import a module as an object attribute. The basic description of what I want to accomplish is that I'm creating a software agent object. This agent will have a set of abilities (functions), but I don't know what these are ahead of … |
| | 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. … |
| | (A quine is a program that produces its own source as its output, typically to a file.) [CODE=Python]import sys ifile = sys.argv[0] counter = 0 istream = open(ifile) source = istream.readlines() source[2] = 'counter = ' + str(counter + 1) + '\n' if counter == 0: original = str(ifile) source.insert(5, …  |
| | I'm thinking about writing a small command line directory management program in Python. The most basic functionality I want is to be able to compare the the files in a directory and sub-directory, and if there are any duplicates then delete the lower most duplicate. I all ready have a …  |
| | Lately I've been writing a lot of code involving the creation of new objects, and I quickly come to find that Python almost always creates a reference to an object instead of a new object. I understand the importance of conserving memory usage, but in this instance I actually need … |
| | 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 …  |
| | Hello. I'm lrh9, a new user. This is my first time visiting these forums. I've posted on [url]www.programmingforums.org[/url] under the same user name. I'm a hobbyist and amateur computer programmer. My primary languages are C++, a custom scripting language for Windows named AutoHotkey, and Python which I've just started out … |
| | So I'm interested in learning about data validation. Especially in Python. Python all ready has several common idioms for data validation. There are several statements that evaluate data. For instance, isinstance(object, classinfo) will check that the given object is an instance of the class or type in classinfo. One idiom … |
| | I want to call another object's methods from another object, and I have no idea how. Can someone please help me? Thank you. |
| | Is it a good idea to help people with object oriented software design and code? I'm asking this because most of the code here is written using the functional programming, and all could probably improve a little or a lot with object oriented design and coding. My first doubt about … |
| | 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 … |
The End.
