📌 1. Key Python Topics to Cover

SI	Section	Topics	Done
1	Core Python	Data types (int, float, str, bool), lists, tuples, sets, dictionaries, type casting, basic operators, comparison operators, and logical operators
2	Control Flow	if-else statements, for loops, while loops, break, continue, pass
3	Comprehensions	List, set, and dictionary comprehensions, filtering elements, nested comprehensions
4	Functions	Defining functions, return values, *args, **kwargs, lambda functions, recursion, default and keyword arguments
5	OOP Concepts	Classes, inheritance, encapsulation, polymorphism, class attributes vs instance attributes, init method, @staticmethod, @classmethod, super(), method resolution order (MRO)
6	Exception Handling	try-except-finally, raising exceptions (raise), custom exceptions, assertions
7	Working with Files	with open() for file handling, file modes ('r', 'w', 'a', etc.), reading large files efficiently (line by line), file reading techniques, context managers
8	Data Structures	Lists, tuples, sets, dictionaries, Stacks (using lists), Queues (using collections.deque), namedtuple, Counter (from collections), DefaultDict (from collections)
9	Pythonic Code	One-liners, list comprehensions, use of any(), all(), sorted() with lambda, ternary operators, zip(), efficient looping with zip() and enumerate()
10	Performance Tips	Generator vs list (using yield), time and space complexity, memory profiling (memory_profiler module), using functools.lru_cache for caching
11	Scripting Skills	Writing command-line interface (CLI) scripts, using argparse for argument parsing, os module for file and directory manipulation, subprocess for running shell commands
12	Concurrency	Basic threading, the Global Interpreter Lock (GIL), multiprocessing basics, asynchronous programming with asyncio
13	Decorators	Function decorators (@decorator_name), class decorators, built-in decorators (e.g., @staticmethod, @classmethod), creating custom decorators, chaining decorators
14	Imp-Standard Libraries	math, collections, itertools, and String Manipulation, Other useful libraries.
15	Iterables vs. Iterators vs. Generators	Iterables vs. Iterators vs. Generators
