#Random Password Generator

This program generates a strong random password based on user preferences for length and character types.

Concepts covered:

• Using Python's 'random' and 'string' modules
• Loops, conditionals, and user input handling
• Building and joining strings dynamically

# Importing the required modules
import random   # For generating random selections
import string   # For accessing predefined character sets (letters, digits, symbols)


def generate_password(length, use_uppercase, use_digits, use_symbols):
    """
    Generates a random password based on user choices.
    
    Parameters:
        length (int): Desired password length
        use_uppercase (bool): Include uppercase letters if True
        use_digits (bool): Include numbers if True
        use_symbols (bool): Include punctuation/symbols if True
    
    Returns:
        str: The generated password
