Python Generators are used to create values one at a time instead of generating all values at once. In this chapter, you will learn about Python generators, how they work, and how they help in saving memory. What is Python Generator? A Python generator is a special type of function that returns an iterator. Instead of using return, it uses the yield keyword to produce values one by one. Each time yield is used, the f...

A Regular expression, abbreviated as RegEx, is a sequence of unique characters that forms a search pattern. We can use RegEx in order to check if a string contains the specified search pattern. By matching a given pattern for a text, it can find the presence and absence of that text and also break the pattern into small parts.

Trainer Coding Prep
HackerRank Coding Prep
Trainer Coding PrepPython is the world’s easiest-to-read yet most powerful programming language. Whenever Netflix recommends movies, banks automate fraud checks, or companies build AI chatbots and backend APIs, Python is the core engine running behind the scenes.
100% Beginner-Friendly: Even if you come from a non-technical degree (B.Com, BA, BBA, B.Sc) and have never written a single line of code, Day 1 starts from installing Python and writing plain-English logic step by step — progressing all the way to enterprise automation, OOP, testing, and production scripts for technical learners.
Key Engineering Capabilities You Will Build:
Purpose: Automate repetitive calculations, business rules, and data validation without manual human errors.
Purpose: Organize and filter thousands of customer, order, or sensor records in milliseconds in memory.
Purpose: Structure large enterprise codebases cleanly so teams of 20+ developers can collaborate safely.
Purpose: Read/write business reports, parse API payloads, and prevent software crashes on bad inputs.

Our mission at MockAttempt Academy is to make job-ready Python engineering, 17,000+ MCQ practice, and Voice AI Interview coaching accessible to every student in India.
Across all 52 syllabus topics in 16 modules, this course includes 376 Timed Topic Mock Tests (17,360 curated MCQs with detailed explanations) and 376 Spoken Voice + MockAttempt AI Technical Interview rounds — ensuring 100% of topics are assessed.
The AI Interviewer speaks each question aloud, listens to your spoken explanation via microphone, converts speech to text live, and sends it to the MockAttempt AI verification agent for scoring and follow-up probing.
All MockAttempt Tech Academy fees are 100% fixed and non-negotiable (₹3,499 (Incl. 18% GST)). We never inflate fake MRPs only to bargain discounts because we refuse to compromise on Senior Industry Expert trainers, small interactive live batches, real cloud/repository labs, daily assessments, or placement mentorship.
Regular Skill Courses offer both Weekday Live Batches (Monday–Friday, 1 Hour/Day between 7:00 AM and 8:00 PM IST) and Weekend Live Batches (Saturday–Sunday, 2 Hours/Day between 7:00 AM and 8:00 PM IST) taught 100% by active Working IT Professionals — students can choose any convenient slot based on trainer availability.
Yes! Because this curriculum includes Python 3.12, your trainer provides guided problem-solving support to break down patterns, edge cases, and optimal complexity so you can confidently crack LeetCode and HackerRank problems.
