Write a program to check the validity of password input by users In Python

A website requires the users to input username and password to register. Write a program to check the validity of password input by users.

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.

Example

If the following passwords are given as input to the program:

ABd1234@1,a F1#,2w3E*,2We3345

Then, the output of the program should be:

ABd1234@1

Hints:

In case of input data being supplied to the question, it should be assumed to be a console input.

Solution:

import re

value = []

items=[x for x in raw_input().split(',')]

for p in items:

    if len(p)<6 or len(p)>12:

        continue

    else:

        pass

    if not re.search("[a-z]",p):

        continue

    elif not re.search("[0-9]",p):

        continue

    elif not re.search("[A-Z]",p):

        continue

    elif not re.search("[$#@]",p):

        continue

    elif re.search("\s",p):

        continue

    else:

        pass

    value.append(p)

print ",".join(value)
