Answer 1

You can use "global" keyword to define a global variable inside the function to access it across the function

Here's how 👇

Answer 2

No, unlike global variables, local variables are meant to be used/accessed in a local scope only, meaning you can't access that "a" outside the function.

Answer 3

Is vice versa possible?
Like in:

def func():
a = 8
print(a)

can we change "a" outside the function?

Answer 4

Carlos, you can do this:

def func():
a = 8
return a

a = func() # a=8
a += 2
print(a) # a=10

Answer 5

Tomáš Konečný That doesn't change the variable inside the function though.

Answer 6

Carlos I just tried to demonstrate how to operate with variables outside of the function... That was your question in one of your previous posts here
