Password.py

Where E is the entropy, R is the pool, and L is the length of the password.

The pool is determined by what type of characters are in the password. For example, there are 26 lowercase characters, so a password containing only lowercase letters would have a pool of 26. There are 26 uppercase characters, so a password containing lower and uppercase characters would have a pool of 52.

After determining the entropy, the password is classified under 5 categories:

• if E < 28, the password is Very Weak.

• if 28 < E < 35, the password is Weak.

• if 35 < E < 59, the password is Good.

• if 59 < E < 127, the password is Strong.

• if E > 127, the password is Very Strong.

Your task is to create a program that takes in a string of text and outputs the strength of the password.

The password should be able to contain upper and lowercase characters, digits, and these symbols:

> symbols = ['!', '@', '#', '$', '%', '&', '(', ')', '-', '_', '[', ']', '{', '}', ';', ':', '"', '.', '/', '<', '>', '?']

You may also have to use import math to gain access to the log function. 

Example:

> Password: abc123

> Weak

Since the password contains only lowercase characters and digits, the pool will be 26 + 10 = 36. The password is 6 characters long. Inputting that into the formula outputs around 31.01 bits of entropy, making this password Weak.
