Python Day 18: Python Loop Challenges: Patterns, Prime Numbers & Sums Explained

πŸš€ Welcome to Day 18 of the Python 30-Day Series!
In this video, we tackle real coding challenges with loops. You’ll learn how to use for and while loops to solve problems like:

βœ… Pattern printing – stars, pyramids, and inverted triangles
βœ… Prime number check – detect whether a number is prime
βœ… Summations – natural numbers, even/odd sums, factorials

πŸ‘‰ These are classic coding exercises often asked in interviews, exams, and competitive programming. By practicing them, you’ll sharpen your logic-building skills and gain more confidence in loops.

πŸ“‚ What you’ll learn today:

Pyramid & inverted pyramid patterns
Prime number check using loops
Sum of numbers, even/odd sums, factorial
Nested loop challenges
