Question

Think I’m going nuts here.

url_request = 0

def somefunction():
    url_request+=1

if __name__ =='__main__':
    somefunction()

Gives me the UnboundLocalError. What important concept am I missing here?

Answer 1

You are assigning to a global variable, which means you need to mark it as a global:

def somefunction():
    global url_request
    url_request+=1

When you assign to a variable in a local scope, it is assumed to be a local variable unless you use a global statement to tell python otherwise first.
