# coding: utf-8def test():    var = 1     def print_var():        print var    <--- var is not in local scope, the var from outer scope gets used    print_var()    print vartest()# 1# 1def test1():    var = 2     def print_var():        print var     <---- var is in local scope, but not defined yet, ouch        var = 3     print_var()    print vartest1()# raise Exception
