+= HELP

[2.537]

Ok so Im quite ew to python and my code looks like this
 

Code:

counter = 1


def question():
     #some code here
     counter += 1

and I get an error saying that counter is not defined that vanishes when I do counetr = counter + 1 but I guess that counter += 1 is more efficient, any thoughts?

the difference is negligible , their speed is almost identical so doesn't matter which ever u choose
