Python 2下
count = 0
while count < 3:
user = input('>>>')
pwd = input('>>>')
if user == 'wy' and pwd == '123':
print "欢迎登陆"
break
else:
print "用户名或者密码错误"
count = count +1
造成以下输出错误:
/System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 "/Users/macmini-2/Desktop/AiGuXuan 2018-04-24 09-01-22/day1.py"
>>>f
Traceback (most recent call last):
File "/Users/macmini-2/Desktop/AiGuXuan 2018-04-24 09-01-22/day1.py", line 30, in <module>
user = input('>>>')
File "<string>", line 1, in <module>
NameError: name 'f' is not defined
Process finished with exit code 1
解决办法:
count = 0
while count < 3:
user = raw_input('>>>')
pwd = raw_input('>>>')
if user == 'wy' and pwd == '123':
print "欢迎登陆"
break
else:
print "用户名或者密码错误"
count = count +1
将input改成raw_input
