Are classes in Python in different files?
- by Asaf
Much like Java (or php), I'm use to seperating the classes to files. Is it the same deal in Python? plus, how should I name the file? Lowercase like classname.py or the same like ClassName.py? Do I need to do something special if I want to create an object from this class or does the fact that it's in the same "project" (netbeans) makes it ok to create an object from it?Read the article

Python new-style classes and __subclasses__ function
- by Fraser Graham
Can somebody explain to me why this works (in Python 2.5) : class Foo(object): pass class Bar(Foo): pass print(Foo.__subclasses__()) but this doesn't : class Foo(): pass class Bar(Foo): pass print(Foo.__subclasses__()) The latter returns "AttributeError: class Foo has no attribute '__subclasses__'" but i'm not sure why. I know this is related to old-style vs. new-style classes but i'm not clear on why that would make this functionality unavailable.Read the article

python: list manipulation
- by Jason S
I have a list L of objects (for what it's worth this is in scons). I would like to create two lists L1 and L2 where L1 is L with an item I1 appended, and L2 is L with an item I2 appended. I would use append but that modifies the original list. How can I do this in Python? (sorry for the beginner question, I don't use the language much, just for scons)Read the article

python script argument misinterpreted in Hudson Execute Shell step
- by chz
When I run my python script in the shell terminal, it works sudo myscript.py --version=22 --base=252 --hosts="{'hostA':[1],'hostB':[22]}" But when I run in Hudson and Jenkins, using Execute Shell step, somehow, the string --hosts="{'hostA':[1],'hostB':[22]}" is interpreted as sudo myscript.py --version=22 --base=252 '--hosts="{'hostA':[1],'hostB':[22]}"' How do we overcome this so that our script would run in Jenkins and Hudson ?

Worst aspect of Python for a newbie
- by schickb
I'm wondering specifically what experienced programmers thought when they started developing in Python. I'm sure the answer depends on your background, but my own personal answer is the conversion of basically anything in the language to a True/False value in boolean contexts. Resulting in "oddities" like: if x: not meaning the same thing as: if x == True: I understand why, but it bugs me, and I certainly had to think about it a bit when I first ran into it.Read the article

Python: read streaming input from subprocess.communicate()
- by Heinrich Schmetterling
I'm using Python's subprocess.communicate() to read stdout from a process that runs for about a minute. How can I print out each line of that process's stdout in a streaming fashion, so that I can see the output as it's generated, but still block on the process terminating before continuing? subprocess.communicate() appears to give all the output at once.Read the article
