+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)
