编写一个程序来接收密码，该程序会告诉用户它的长度，以及它是太大、太小还是太强

Question

#This program prompts the user to enter a password using the input function
#The program assigns the input to a variable named passWord
# The len function is used to get the length of the data in the passWord variable
#the len function puts this value in the variable passwordLength
#The length of the passwordLength variable is printed.

#This is the start of the program

minLength = 6       #this is the minimum password length
maxLength = 12      #this is the maximum password length
passWord = input("please enter a new password – ")

passwordLength = len(passWord)
if passwordLength minLength: #this is the line with the syntax error
    print("your password is " + str(passwordLength) + " characters long")
    print("your password is too short")
    print("your password must be greater than minLength characters")
if passwordLength maxLength:
    print("your password is " + str(passwordLength) + " characters long")
    print("your password is too long")
    print("your password must be less than maxLength characters")
if (passwordLength  minLength) and (passwordLength  maxLength):
    print("Thank you for creating a strong password!")

这是显示的错误信息

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/bin/pythonanywhere_runner.py", line 26, in _pa_run
    code = compile(f.read(), filename.encode("utf8"), "exec")
  File "/home/rocegueda/password.py", line 14
    if passwordLength  minLength:
                       ^
SyntaxError: invalid syntax

如何修复第 14 行的语法错误？不知道该怎么做，因为我是新手。非常感谢所有帮助。

您只需按照概述添加比较运算符 here。对于您的特定代码，这里是必需的运算符：

#This program prompts the user to enter a password using the input function
#The program assigns the input to a variable named passWord
# The len function is used to get the length of the data in the passWord variable
#the len function puts this value in the variable passwordLength
#The length of the passwordLength variable is printed.

#This is the start of the program

minLength = 6       #this is the minimum password length
maxLength = 12      #this is the maximum password length
passWord = input("please enter a new password – ")

passwordLength = len(passWord)
if passwordLength < minLength: #this is the line with the syntax error
    print("your password is " + str(passwordLength) + " characters long")
    print("your password is too short")
    print("your password must be greater than minLength characters")
if passwordLength > maxLength:
    print("your password is " + str(passwordLength) + " characters long")
    print("your password is too long")
    print("your password must be less than maxLength characters")
if (passwordLength >= minLength) and (passwordLength <= maxLength):
    print("Thank you for creating a strong password!")

请注意最后一种情况，您需要将最小和最大密码长度包含为 True。
