Udemy – Python Coding Interview Prep 2026: 70+ Real Problems

Preparing for a Python coding interview is not about memorizing a long list of solutions. It’s about learning how to recognize patterns, break down unfamiliar problems and choose an effective approach when the answer is not obvious. This course gives you structured, hands-on practice with 70+ coding interview problems designed to help you become a more confident and systematic problem solver.

You’ll work through a carefully structured progression covering:

• arrays and strings fundamentals
• hash maps, sets and frequency patterns
• two pointers and sliding window techniques
• stacks, queues and heaps
• binary search, sorting and intervals
• linked lists
• binary trees and binary search trees
• graphs and graph algorithms
• backtracking
• dynamic programming

You’ll also tackle practical Python interview patterns involving custom iterators, generators, decorators and an LRU cache.
