I have two classes in separate files, a.py and b.py. I can not modify a.py in any way. The log output is: I want to change __name__ so that a child class’s call should log called in b. My project logs its module name as part of the output. However, when I inherit a class and call the parent class

Python: cache a local function variable for subsequent calls
In C/C++, a function can declare a local variable as static. When doing so, the value remains in memory and is available to subsequent calls to the function (this variable is no longer local, but that’s besides the point). Is there a way to do something similar in Python, without having to declare any g…
Setting back global variables back to their default value
In game,I have created some global variables whose value changes when a certain action occur.When I restart the game,I want their value to be set again to their initial value. I can change global variable value by equilazing it back to its original value. Is there any other way to do so,when there are lot of …
How to avoid using global variables?
I use global variables but I’ve read that they aren’t a good practice or pythonic. I often use functions that give as a result many yes/no variables that I need to use in the main function. For example, how can I write the following code without using global variables? Answer One could ask what re…
Access a global pointer in C from python using ctypes
I know that if I have a global variable (let’s say a double called N) I can read it using: but what if my variable is a pointer? How can I read the contents of the pointer in to a python list? To be clearer, N is declared in the following way in the shared library: Answer Given this (Windows)
How to access Aʟʟ global variables in a function?
I’m trying to mimic the matlab load and save functions. I’m following this thread: Shelve Code gives KeyError It is smart. However, if I write that code in a separate module, and try to import that module and invoke that function, then it can’t access the global variables. Specifically, I wr…
Reason for globals() in Python?
What is the reason of having globals() function in Python? It only returns dictionary of global variables, which are already global, so they can be used anywhere… I’m asking only out of curiosity, trying to learn python. I can’t really see the point here? Only time I would need it, was if I …
Why isn’t the ‘global’ keyword needed to access a global variable?
From my understanding, Python has a separate namespace for functions, so if I want to use a global variable in a function, I should probably use global. However, I was able to access a global variable even without global: Why does this work? See also UnboundLocalError on local variable when reassigned after f…
