Variable scope in Python?

Question

I want to change a variable using a function, but I get the error: local variable referenced before assignment. How can I use global variables inside functions?

Answer 1

thing=0

def funky():
global thing
print(thing)

funky()
# you can do multiple globals by using commas

Answer 2

ok thx

Answer 3

@Tobi what do you mean with implementing a class?

I am building something using the cmd module, and I didnt find a different way to do this

Answer 4

I dont think that would work with the cmd module, or at least it would be unnecessary complicated

Answer 5

In many cases I'd categorize what you want to do there as a code smell. Is there a reason you don't want to implement a class here?

Answer 6

You can define a class, which has your function as a method. This method will then be able to change attributes of an instance of that class.
