how to send nested functions data to another function in python

Question

I want to display the value of a variable in world function.

def base():
    
    print("Hello World")
    
    def child():
        a = 10
        return a
    
def world():
    num = base.child() # error -------
    print(num)
    
world()```

What does base represent in the expressions base.child()? A scalar value, an object, a class, a method, or what? — Nicholas Hunter

I suggest calling child in base.

def base():
    
    print("Hello World")
    def child():
        a = 10
        return a
    return child()
def world():
    num = base()
    print(num)
    
world()

Now it's working, but I want another way (Don't return the child function from base function)

I don't think there's any way to access the inner function from outside. That's kind of the point. The best you can hope for is to access the results of the inner function, exactly as @BuddyBob suggests. You might find this informative. Python Inner Functions: What Are They Good For?
