Calling def from inside of another def

Question

I want to call a def that is inside of another def Example:

def 1(a,b):
      Print(a,b)

      Def 2 (c,d):
         Print(c,d)

The thing i want to do is like we call a function from a class like

class().def(variables)

Iwant to do something like the above code Something like

def1().def2(variables)

Thanks :D

Ihave this code

I need to call the printer Function but i cant

I tried to make q text object global but i get error The print hi command doesnt work because printer fumc is on another func

Functions defined inside another function cannot be accessed from the outside, unless a reference to that function is returned or assigned to another variable by the outer function. — quamrana, May 26 '21 at 17:31

I'm sorry but the inner function is protected, you need to put it outside. If you want to still group your functions just use a class. — Hemi03, May 26 '21 at 17:34

You cannot call a function inside another function, unless you return it.

What this means, that you cannot do this:

def func1(a,b):
      print(a,b)

      def func2 (c,d):
         print(c,d)

func1().func2()

What you can do however, is this:

def func1(a,b):
    print(a,b)

    def func2 (c,d):
       print(c,d)
    return func2

func2 = func1()
func2()

As to why you would do this is not clear to me, but if you must, this will let you do that.

If possible, I would recommend putting both in a class.
