Question 18
Level 3

Question:
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
'''

import re
X = input("Enter passwords:")
val = list()
for x in X.split(','):
    if re.search("[0-9]+",x) and re.search("[a-z]+",x) and str(re.search("[a-z]+",x)).upper() and len(x)>=6 and len(x)<=12 and re.search("[$#@]",x):
        val.append(x)
        print(val)
