How to return a variable of a local function to an outside variable?

Question

example
def hello():
x=input(hello, what is your name?)
return x
x= the value returned from hello

I want to assign the result of the function hello() to a global variable in this case the global x. is this possible or would I have to use a function other than return?

Answer 1

You can also use you global variable inside a function: it's just requiring to be declared as 'global' variable for write access:

var x = 42
def func():
print(x)
func()

will output 42 (global var is accessible for reading), but:

var x = 42
def func():
x = "spam"
print(x)
func()
print(x)

will output 'spam' and 42 on next line (x is considerated as local var as you assign a value to it)... however, doing:

var x = 42
def func():
global x
x = "spam"
print(x)
func()
print(x)

... will output 2 times 'spam' on 2 separated lines (x inside function is declared as global, so the assignment will write the global variable) ;)

Answer 2

In your example, you just have to do :
x=hello()
