How To Pass Variables In Python

Question

i thought the return statement sort of allowed other functions to use a variable
But that doesnt seem to be the case
so if it doesn't, then what does it do?
And how can i make a variable accessible to other functions?

Answer 1

hmmm
now you asked the right question

thers 2 type of variable

local
global

locals r created in func only used by that function

globals r created globally
not in any func. body

any func can use them

as ur all result variables r in functions they r local ; thus cant be used by any other func

Answer 2

if var not declared in function :
var=global
elif var is in function :
if var has keyword global :
var= global
else :
var= local

why cant other functions use a variable that is 'returned' by a function

even after correcting that it still didnt work
because of 'result' not being passed to the 'finish()' function
