Python Calling a function in another function

I am reading the book Python Programming for the Absolute Beginner by Mike Dawson and I was struck by a question that I had regarding functions.

Observing the code below

def func_1():
    name = input('What is your name?')
def func_2():
    print(name)

func_2()

I know that I cannot call the variable name in function 2 as it is local to function 1.

However, why can I call a function inside another function and then find the value of the user's input as such below?

def func_1():
    name = input('What is your name?')
    return name
def func_2():
    user_input = func_1()
    print(user_input)

func_2()
