Password Generator in Python

This is a simple password generator script written in Python. It generates secure passwords of varying lengths, combining lowercase letters, uppercase letters, and numbers to ensure password strength.

Features

• Random Password Generation: Generates random passwords using lowercase letters.
• Uppercase and Number Replacement: Automatically replaces some characters with uppercase letters and digits.
• Customizable Length: Users can input the number of passwords and the length of each password.
• Ensures Minimum Length: Passwords shorter than 3 characters are automatically adjusted to the minimum length.

How It Works

The script generates passwords based on user input. For each password:

1. It selects random lowercase letters.
2. It replaces some characters with uppercase letters.
3. It replaces a few characters with numbers.
4. It returns a list of generated passwords, which are displayed to the user.

How to Use

1. Clone the Repository:

   git clone https://github.com/yourusername/password-generator-python.git
   cd password-generator-python

2. Run the Script: Run the script using Python:

   python password_generator.py

3. Input the Number of Passwords: The script will ask you how many passwords you'd like to generate.

4. Input the Length of Each Password: You can specify the desired length for each password. Passwords shorter than 3 characters will be automatically adjusted to the minimum length.

Example

How many passwords do you want to generate? 2
Generating 2 passwords
Minimum length of password should be 3
Enter the length of Password #1 8
Enter the length of Password #2 5
Password #1 = a9cTdefg
Password #2 = jklMn

Code Breakdown

• generatePassword(pwlength): This function generates a list of passwords based on the input lengths. It builds a password by selecting random letters and replacing some with uppercase letters and numbers.

• replaceWithNumber(pword): Replaces random characters in the first half of the password with digits.

• replaceWithUppercaseLetter(pword): Replaces random characters in the second half of the password with uppercase letters.

• main(): The main function prompts the user for input (number of passwords and lengths), calls the generatePassword function, and displays the generated passwords.

Requirements

• Python 3.x
