Best way to put functions python

Question

I bring a few days working on python coming from Matlab and I have the next doubt:

I had a matlab program with a lot of functions defined at the end of my m-file. Matlab recognizes those functions even if I call them at the beginning and they are defined at the bottom of my code.

Now, with python, I don't know what is the best way to put the functions because python needs to know the definition of the functions before calling them. I don't want to create a new file for each function. I would like to put all functions together but I can't figure it out. I hope you can help me.

Thx,

Another way you can have all the functions is to add a function that does everything you want it to do:

def main():
    #do stuff
    f()
    g()
    ...

And add this to the end of the file:

if __name__ == '__main__':
    main()

This will only execute if your file is the main file. If you import your file from another file, then it won't execute all the code in main().
