Password Generator

This command-line Python tool allows users to generate a random password based on their desired criteria, including lowercase letters, uppercase letters, digits, and special characters.

Features

Customizable Character Sets:

• Users can choose which character types (lowercase, uppercase, digits, punctuation) are included in the generated password.

Dynamic Length Input:

• Users are prompted to specify the password length, ensuring that the password fits their requirements.

Error Handling & Validation:

• The script validates the user’s input for password length, requiring a valid integer before proceeding. It also checks that at least one character type is selected.

Installation

1. Ensure you have Python 3 installed.
2. Clone this repository or download the script file.
3. Install any necessary dependencies (though this tool only uses the standard library, so no additional installations should be needed).

Usage

Run the script:

python password_generator.py

Follow the prompts in the terminal:

• Password Length: Enter the desired number of characters (must be a valid integer).
• Include Lowercase? (y/n)
• Include Uppercase? (y/n)
• Include Digits? (y/n)
• Include Special Characters? (y/n)

Once all inputs are provided, the script generates and displays a random password that meets the specified criteria.

Example

• How many characters would you like your password to be? 12
• Would you like lower case letters? (y/n) y
• Would you like upper case letters? (y/n) y
• Would you like digits? (y/n) y
• Would you like special characters? (y/n) n
• Example Output:
  • aBc9dE3fGhX2

Code Overview

• Input Validation:
  • The script uses a while True: loop to repeatedly prompt the user for a password length until a valid integer is received.
• Character Type Verification:
  • It checks whether the user selected at least one character type. If not, the script notifies the user and exits.
• Random Selection:
  • Each character in the password is chosen randomly from the selected character sets.
