Assuming the following snippet:
a = None def set_a(): global a a = 10+2 print(a)
The result is expected to be
12, so why does it remain as
None and won’t update?
I’ve been looking for similar questions on stackoverflow but didn’t find a proper explanation/solution. How exactly can I access the modified value of a global variable which has been updated inside a function from outside of it?
Any help is appreciated in advance.
>>> a = None >>> >>> def set_a(): ... global a ... a = 10+2 ... >>> set_a() >>> >>> print(a) 12
