How to pass parameters to functions inside of fuctions

October 27, 2022

There is something in Python that has been bugging me for a long time. I can’t figure out how to pass parameters from one function to the functions that are defined inside of that function.

def func1(arg1):
    def func2(arg1):
        print(arg1)
    func2()
var1 = 123
func1(var1)

Here func1 and func2 should have the same parameters but don’t.

>Solution :

Can’t you use it like this?

def func1(arg1):
    def func2(): <-- Removed parameter 
        print(arg1)
    func2()
var1 = 123
func1(var1)

Because when you are calling func2 inside func1, the arg1 in func2 is undefined since you passed no parameters; you should read about global and local variables in programming.
