python - 简单的密码程序

Question

我正在尝试制作一个简单的小程序，告诉用户密码错误。
但是，当我希望程序取回他们输入的密码并说这是错误的时，它不会让我这么做。有人帮助我..

username = raw_input("Please enter your username: ")
password = raw_input("Please enter your password: ")
fail1 = raw_input("Your password is very insecure, make a new one: ")
print "Your password [password] is too weak!"

Answer 1

Python 不会神奇地格式化字符串，您需要显式地这样做:

print "Your password {} is too weak!".format(password)

参见Format string syntax了解 .format() 方法如何工作的更多信息。

或者，使用以下任意一种:

print "Your password", password, "is too weak!"
print "Your password %s is too weak!" % password
import string
template = string.Template("Your password ${password} is too weak!")
print template.substitute(password=password)
