Password Strength Checker with Keyword Rules

Medium ⏱ 12 min 47% acceptance ★★★★☆ 4.4
Write a function password_strength(password) that returns "Strong" if the password is at least 8 characters long AND contains at least one digit AND at least one uppercase letter; returns "Medium" if it is at least 8 characters but is missing a digit or an uppercase letter (but not both missing); and returns "Weak" otherwise.

Examples

Example 1
Input
password_strength("Abcdef12")
Output
Strong
Explanation

Length >= 8, has a digit (1,2) and an uppercase letter (A).

Example 2
Input
password_strength("abcdefgh")
Output
Weak
Explanation

Length is fine but both digit and uppercase are missing, so it does not qualify as Medium.

Example 3
Input
password_strength("Abcdefgh")
Output
Medium
Explanation

Length >= 8 and has uppercase, but no digit -- exactly one requirement missing.

  • password is a non-empty string.

Hints

Hint 1

Use any(ch.isdigit() for ch in password) and any(ch.isupper() for ch in password).

Hint 2

Count how many of the two extra conditions (digit, uppercase) are satisfied, then branch on length and that count.
