Write a program that asks the user to enter a password, and then checks it for a few different requirements before approving it as secure and repeating the final password to the user.

The program must re-prompt the user until they provide a password that satisfies all of the conditions. It must also tell the user each of the conditions they failed, and how to fix it. If there is more than one thing wrong (e.g., no lowercase, and longer than 15 characters), the program must print out all of the things that are wrong, and how to fix them.

The program follows these rules for passwords:

1. The password must contain at least one lowercase letter.

2. The password must contain at least one uppercase letter.

3. The password must be between 6 and 20 characters, inclusive.

   a. If the password is between 6 and 13 characters, inclusive, it must contain a 7 somewhere in the password.

   b. If the password is between 14 and 20 characters, inclusive, itmust contain a 2 somewhere in the password.

4. The password cannot contain the characters 0 and O (zero anduppercase o) at the same time. (It can contain a 0 or an O, just notboth at the same time. It may also contain neither.)

For this part of the homework, you must have an in-line comment at the top of each of your programs individual if, elif, and else statements, explaining what is being checked by that conditional.

(HINT: Think carefully about what your conditionals should look like. If necessary, draw a truth table to help figure out what different inputs will do. Using a Boolean flag will also likely make this easier.)

(See the next page for sample output.)

Here is some sample output for hw4_part3.py, with the user input in blue. (Yours does not have to match this word for word, but it should be similar.)
