this question has answer here: how change variable after defined in python 5 answers what doing wrong here? counter = 0 def increment(): counter += 1 increment() the above code throws unboundlocalerror . python doesn't have variable declarations, has figure out scope of variables itself. simple rule: if there assignment variable inside function, variable considered local. [1] thus, line counter += 1 implicitly makes counter local increment() . trying execute line, though, try read value of local variable counter before assigned, resulting in unboundlocalerror . [2] if counter global variable, global keyword help. if increment() local function , counter local variable, can use nonlocal in python 3.x.
