本文实例讲述了Python使用pickle模块报错EOFError Ran out of input的解决方法。分享给大家供大家参考,具体如下:
遇到了 EOFError:Ran out of input 不到为什么这样,最后用捕获异常的办法解决掉了,暂时对程序本身没有啥影响,代码如下:

def register():

open_date = usr_date() if usr_date() else {}
if usr_name in open_date.keys():
print ( '用户已存在,请登录' )
return False
usr_password = input ( '请输入你的密码:' )
usr_dic[usr_name] = usr_password
update_usr(usr_dic)
return print ( '注册成功' )
def Sign_in():
'登录'
pass
def login_index():
while True :
usr = input ( '1.注册 2.登录 0.退出' )
if usr = = '1' :
register()
elif usr = = '2' :
Sign_in()
else :
break

希望本文所述对大家Python程序设计有所帮助。
