     How This Course Helps You Prepare

If you’re aiming for a career in AI Engineering, where Python is the backbone of machine learning frameworks like TensorFlow and PyTorch, having strong fundamentals is non-negotiable. This course ensures you can confidently answer coding round questions, theory-based OOP queries, data structure challenges, and system design-related Python problems.

You'll learn how to:

• Interpret tricky syntax and identify common pitfalls

• Understand memory management, scope, and execution flow

• Apply functional and object-oriented programming effectively

• Work with files, modules, APIs, and databases using Python

• Solve complex problems using generators, decorators, concurrency, and more

     Sample Question & Answer (From Real Practice Tests)

Question:
What is the output of the following code?

python

1

2

3

4

5

6

⌄

def func(x, lst=[]):

lst.append(x)

return lst

print(func(1))

print(func(2))

A) [1] then [2]
B) [1] then [1, 2]
C) [1, 2] then [1, 2]
D) [1] then [2, 1]

Correct Answer: B) [1] then [1, 2]

Explanation:
In Python, default arguments are evaluated only once when the function is defined, not each time the function is called. The list lst is a mutable default argument and persists across function calls. On the first call, 1 is appended to the default list, returning [1]. On the second call, the same list (now containing [1]) is used, so 2 is appended, resulting in [1, 2]. This is a classic Python gotcha often tested in interviews. To avoid this behavior, use None as the default and initialize inside the function.

Another Sample Question:

Question:
Which of the following statements about Python’s Global Interpreter Lock (GIL) is true?

A) It allows multiple threads to execute Python code simultaneously
B) It prevents race conditions by enabling thread-safe garbage collection
C) It ensures that only one thread executes Python bytecode at a time
D) It improves performance in multi-core systems for CPU-intensive tasks

Correct Answer: C) It ensures that only one thread executes Python bytecode at a time

Explanation:
The GIL is a mutex in CPython that protects access to Python objects, preventing multiple threads from running Python bytecode concurrently. While threading can still be useful for I/O-bound operations, the GIL limits true parallelism in CPU-intensive multithreaded programs. For such cases, multiprocessing is preferred. Understanding the GIL is crucial for system design and performance optimization interviews, especially for AI engineers dealing with large-scale model training.

Full Coverage: 6 Comprehensive Sections

To ensure complete mastery, this course is divided into six well-structured sections, each focusing on a key area of Python development:

Section 1: Python Fundamentals

Master the building blocks of Python including variables, data types, operators, control flow, loops, strings, and basic error handling. Build a rock-solid foundation essential for writing correct and efficient code.

Section 2: Data Structures

Deep dive into lists, tuples, dictionaries, sets, list comprehensions, nested structures, shallow vs deep copy, and working with JSON. Learn how to choose the right data structure for optimal performance.

Section 3: Functions and Scope

Explore function definitions, argument types, lambda functions, recursion, closures, generators, iterators, and scoping rules (LEGB). Understand higher-order functions and functional programming patterns widely used in modern Python.

Section 4: Object-Oriented Programming (OOP)

Learn classes, objects, inheritance, polymorphism, encapsulation, method overriding, abstract classes, magic methods, and class/static methods. These concepts are critical for designing scalable applications and are frequently asked in senior-level interviews.

Section 5: Files, Modules & Packages

Work with file I/O, context managers, CSV/JSON handling, OS and sys modules, package creation, virtual environments, and standard libraries. Gain practical knowledge needed for scripting, automation, and backend services.

Section 6: Advanced Python Concepts

Tackle advanced topics like regular expressions, threading and multiprocessing, datetime handling, SQLite integration, API requests, web scraping, type hints, dataclasses, descriptors, and metaprogramming. These are commonly seen in AI, DevOps, and full-stack engineering roles.
