Ever notice how websites tell you if your password is “weak,” “medium,” or “strong”? In this project, you will write a program that analyzes passwords and rates their strength based on multiple criteria.

Your program must meet the following specifications:

• Create a function called check_password_strength that takes a password as input and returns a strength rating
• Check for the following criteria:
  • Length: Password must be at least 8 characters long
  • Uppercase letters: Password contains at least one uppercase letter (A-Z)
  • Lowercase letters: Password contains at least one lowercase letter (a-z)
  • Digits: Password contains at least one number (0-9)
  • Special characters: Password contains at least one special character (!@#$%^&*)
• Assign a score based on how many criteria are met:
  • 0-1 criteria met: “Very Weak”
  • 2 criteria met: “Weak”
  • 3 criteria met: “Medium”
  • 4 criteria met: “Strong”
  • 5 criteria met: “Very Strong”
• Ask the user to enter one password
• Print the strength rating
• Print which criteria were met and which were not

For example:

Checking for Character Types

You can check if a string contains uppercase, lowercase, digits, or other characters by looping through each character:

password = "MyPassword123!"

# Check if string contains uppercase
has_upper = False
for char in password:
    if char.isupper():
        has_upper = True

print(has_upper)  # True

The isupper(), islower(), and isdigit() methods check a single character.

Example Code

def check_password_strength(password):
    """Analyze password strength and return a rating."""
    # TODO: Check each criterion and count how many are met
    # TODO: Determine strength rating based on count
    # TODO: Return the rating

password = input("Enter a password: ")
# TODO: Call check_password_strength()
# TODO: Print the rating and which criteria were met/not met
