You can use "global" keyword to define a global variable inside the function to access it across the function Here's how 👇 https://code.sololearn.com/czPAkBDJSYT0/?ref=app

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.

Is vice versa possible? Like in: def func(): a = 8 print(a) can we change "a" outside the function?

Carlos, you can do this: def func(): a = 8 return a a = func() # a=8 a += 2 print(a) # a=10

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

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
