What is t...

Him I have a dictionary dict1['a'] = [ [1,2], [3,4] ]. I need to generate a list out of this dictionary as l1 = [2, 4] i.e., a list out of the second element of each inner list. It can be a separate list or even the dictionary can be modified as dict1['a'] = [2,4]. Any idea would be appreciated. ...
If I have a function (in Python 2.5.2) like: def sample_func(): a = 78 b = range(5) #c = a + b[2] - x My questions are: How to get the local variables (a,b) of the function from outside without using locals() inside the function? (kind of reflection) Is it possible to set a local variable (say x) from outside so that the...

For example: C++ object pyInstance = GetLocalDict()["makeNewGamePlay"](); CGEPYGameMode* m_pGameMode = extract< CGEPYGameMode* >( pyInstance ); pyth: cla...

Hello, I'm creating a class, but having some trouble with the namespacing in python. You can see the code below, and it mostly works ok, but after the call to guiFrame._stateMachine() the time module is somehow not defined anymore. If I re-import the time module in _stateMachine() it works. But why is the time module not in the namesp...

I know this question is kind of stupid, maybe it's a just a part of writing code but it seems defining simple functions can really hurt performance severely... I've tried this simple test: def make_legal_foo_string(x): return "This is a foo string: " + str(x) def sum_up_to(x): return x*(x+1)/2 def foo(x): return [make_lega...
I have a DLL containing a C function with a prototype like this: int c_read_block(uint32 addr, uint32 *buf, uint32 num); I want to call it from Python using ctypes. The function expects a pointer to a chunk of memory, into which it will write the results. I don't know how to construct and pass such a chunk of memory. The ctypes documen...
