How to get parent directory from existing func not user func ?

[Larz60+]

You can the parent of a function with inspect:

This combined with Nilamo's code could be the start of a useful way to create program flow graphically.

import inspect

def function1():
   print('Function1 called from: {}'.format(inspect.stack()[1][3]))

def function3():
   print('Function1 called from: {}'.format(inspect.stack()[1][3]))
   function1()

def function2():
   print('Function2 called from: {}'.format(inspect.stack()[1][3]))
   function3()

def main():
   function2()


if __name__ == '__main__':
   main()

results:

Output:
Function2 called from: main
Function1 called from: function2
Function1 called from: function3

Process finished with exit code 0
