| 2 | + |
| 3 | +> This code is a simple password strength checker. |
| 4 | +It evaluates the strength of a user's password based on the presence of |
| 5 | +uppercase letters, lowercase letters, digits, spaces, and special characters. |
| 6 | + |
| 7 | +### About the code: |
| 8 | + |
| 9 | +- The codebase is break down in two file `password_strength_checker.py` and `main.py`. |
| 10 | + |
| 11 | +`password_strength_checker.py` The function evaluates password strength based on character types (uppercase, lowercase, digits, spaces, special characters) and provides feedback on its security. |
| 12 | +and `main.py` contains basic code. |
| 13 | + |
