Question

好的，我正在编写一个简单的登录系统，这是代码

import time
for counter in range(5):
  username=str(raw_input("Please enter your username"))
  password=str(raw_input("Please enter your password"))
  if username =="bros10":
     print "",username,"entered"
     time.sleep(4)
     print "You got the username right"
     if password =="brosbros10":
        print "You got the password right"
        print "Welcome to the system"
        break

else:
    print "Try again"

当我运行它时会发生什么，它将打印此位打印＆＃34;＆＃34;，用户名，＆＃34;输入＆＃34;输入密码后任何帮助表示赞赏

Answer 1

移动它：

print "",username,"entered"

在此之前：

password=str(raw_input("Please enter your password"))

现在你的程序将要求输入用户名，重复输入的用户名（如果他们输入bros10，告诉用户他们说得对，）然后要求输入密码，然后睡4秒。

或者，您可以将password=行放在此前一行

if password =="brosbros10":

如果您希望在等待4秒并重复用户输入后要求输入密码。

Answer 2

如果我理解你是正确的，那么在输入密码之前你想要print "",username,"entered"。那应该是：

import time
for counter in range(5):
  username=str(raw_input("Please enter your username"))
  print "",username,"entered"
  if username == "bros10":
     print "You got the username right"
     password=str(raw_input("Please enter your password"))
     time.sleep(4)
     if password =="brosbros10":
        print "You got the password right"
        print "Welcome to the system"
        break

  print "Try again"

Python 2.7 for循环而没有打印正确的时间
