Declare function at end of file in Python

Question

Is it possible to call a function without first fully defining it? When attempting this I get the error: \"function_name is not defined\". I am coming from a C++ ba

Answer 1

If you are willing to be like C++ and use everything inside a functions. you can call the first function from the bottom of the file, like this:

def main():
    print("I'm in main")
    #calling a although it is in the bottom
    a()

def b():
   print("I'm in b")

def a():
   print("I'm in a")
   b()

main()

That way python is first 'reading' the whole file and just then starting the execution
