Nested function

Question

how can I call a nested function from function that are out side of the main function

def main()
def a()

def fun()
def b()
# do something
# call function a

Answer 1

since a() is a local function inside the main function, without using global functions i dont see any elegant way how you could run it from another function outside of the main function. But my solution would be:

def main(call_a = False):

def a():
print("hi")

if call_a is True:
a()

def func():
def b():
call_nested_func_inside_main = True
main(call_nested_func_inside_main)

b()

func()

So you call a nested function by using some arguments from the functions outside of the parent function.

Answer 2

I have follow up question what if both function are in class
the class as two nested function
