Random Password Generator

The "Random Password Generator" is a Python program that allows users to generate random passwords based on their preferences. This project is designed to help you practice Python programming and gain experience in working with strings, randomization, and user interaction.

Key Features:

1. Generate Password: Users can create random passwords of specified lengths with options for uppercase letters, lowercase letters, digits, and symbols.
2. Save Password: The program offers the option to save generated passwords to a file for later use.
3. User-Friendly Interface: The user interacts with the program through a command-line interface, making it easy to use.

How to Use:

1. Run the Python program.
2. Specify the desired password length.
3. Choose whether to include uppercase letters, lowercase letters, digits, and symbols in the password.
4. The program generates a random password based on your preferences.
5. You can choose to save the password to a file.

Suggested Enhancements:

To further expand and enhance this project, you can consider adding features like:

• Password Strength Evaluation: Implement a feature that evaluates the strength of the generated passwords.
• Password History: Allow users to store and manage a history of generated passwords.
• Custom Character Sets: Enable users to define their custom character sets for password generation.

Feel free to explore and customize this project to suit your learning goals and interests. Happy coding!

Random Password Generator

Password Length: 12
Use Uppercase Letters? (Y/N): Y
Use Lowercase Letters? (Y/N): Y
Use Digits? (Y/N): Y
Use Symbols? (Y/N): N

Generated Password: AbCdeFgH1234

Save the password to a file? (Y/N): Y
Enter the filename: my_password.txt
Password saved to my_password.txt

Before running the program, make sure you have Python installed on your system. Enjoy generating random passwords!
