Python creating username and password program
提问by Polly the Programmer
I am just a beginner programmer as of right now, and I am trying to create a username/password program. Here is my code below:
我现在只是一个初学者程序员，我正在尝试创建一个用户名/密码程序。这是我的代码如下：
username = 'Polly1220'
password = 'Bob'
userInput = input("What is your username?\n")
if userInput == username:
a=input("Password?\n")
if a == password:
print("Welcome!")
else:
print("That is the wrong password.")
else:
print("That is the wrong username.")
Whenever I run my program and input the correct password as shown, it always says that the password is incorrect.
每当我运行我的程序并输入正确的密码时，它总是说密码不正确。

You need to assign the second input statement to userInput:
您需要将第二个输入语句分配给 userInput：
if userInput == username:
userInput = input("Password?\n")
if userInput == password:
print("Welcome!")
else:
print("That is the wrong password.")
else:
print("That is the wrong username.")

You forget asign the variable:
您忘记分配变量：
if userInput == username
userinput = input("Password?\n")
if userInput == password:
print("Welcome!")
else:
print("That is the wrong password.")
else:
print("That is the wrong username.")
