Day 2: Work with lists, tuples, dictionaries, and sets.
Day 3: Master OOP concepts – classes, inheritance, polymorphism, and encapsulation.
Day 4: Handle exceptions and logging in Python.
Day 5: Explore Python’s built-in modules and libraries (
collections,itertools,functools).Day 6: Solve LeetCode problems on arrays and strings.
Day 7: Review and practice coding exercises.
Tip: Be ready to explain the difference between deepcopy() and copy() in Python.
Week 2: Advanced Python & Algorithms
Focus: Multithreading, file handling, and algorithm optimization.
Daily Goals:
Day 1: Learn Python’s threading and multiprocessing.
Day 2: Work with file handling (
open(), reading/writing files).Day 3: Explore Python’s generators and iterators.
Day 4: Study recursion, searching, and sorting algorithms.
Day 5: Implement dynamic programming problems.
Day 6: Solve algorithm-based problems on LeetCode.
Day 7: Mock problem-solving session.
Tip: Expect questions on when to use recursion vs. iteration.
Week 3: Web Development, APIs & Databases
Focus: Django, Flask, REST APIs, and database interactions.
Daily Goals:
