python 作用于的问题（超级有意思）

str_ok = 'jack'
def cs_first():
    try:
        print("111=", str_ok)
        print("222=", 4 / 0)
        # try:
        #     print("1212=", str_ok)
        #     pass
        # except:
        #     pass
        # finally:
        #     print("1414=", str_ok)
        #     pass
        # pass
    except:
        # str_ok = 'lucy'
        print("222=", str_ok)
    finally:
        # str_ok = 'uuuu'
        print("333=", str_ok)


cs_first()

总结：分步，打开finally，except里面的str_ok 变量，看看作用域 或 作用。
