【解決方法】有効なパスワードを検索しています

A website requires the users to input username and password to register. Write a program to check the validity of password input by users (using tuples only) Following are the criteria for checking the password: 1. At least 1 letter between [a-z] 2. At least 1 number between [0-9] 1. At least 1 letter between [A-Z] 3. At least 1 character from [$#@] 4. Minimum length of transaction password: 6 5. Maximum length of transaction password: 12 Your program should accept a sequence of comma separated passwords and will check them according to the above criteria. Passwords that match the criteria are to be printed, each separated by a comma. If none of the password is valid, you should print "invalid"

            if k.isalpha() or k.isdigit() or (k in ["@","#","$"]):
                print(k,end="")
