Day 9 of DSA Journey: Python Arrays and Algorithms

𝐃𝐚𝐲 𝟗 𝐨𝐟 𝐦𝐲 𝐃𝐒𝐀 𝐢𝐧 𝐏𝐲𝐭𝐡𝐨𝐧 𝐣𝐨𝐮𝐫𝐧𝐞𝐲 — 𝐭𝐨𝐝𝐚𝐲 𝐰𝐚𝐬 𝐥𝐞𝐬𝐬 𝐜𝐨𝐝𝐢𝐧𝐠, 𝐦𝐨𝐫𝐞 𝐮𝐧𝐝𝐞𝐫𝐬𝐭𝐚𝐧𝐝𝐢𝐧𝐠 🧩 Not every day is about solving problems. Today was about building clarity. I focused on Python arrays and understanding them properly before jumping into heavy problem solving. Here’s what I covered: • How arrays are implemented in Python • Basic operations — add, remove, update elements • Key properties of arrays and how they behave Then I moved to the fundamentals of: • Searching algorithms • Sorting algorithms Today was mostly theory + understanding the “why” behind things — and honestly, this step feels underrated. Because better understanding today = faster problem solving tomorrow. 📌 Plan for Day 10: Applying all of this through problem solving on arrays Slowly shifting from learning → applying. #DSA #Python #DataStructures #Algorithms #CodingJourney #LearnInPublic #Programming #SoftwareDevelopment #ComputerScience #TechLearning #CodeNewbie #100DaysOfCode #Developers #CodingLife

Still confused about Modules, Packages, and Libraries? You’re not alone, but here’s the simplest way to understand it 👇 🌱 Module = A single Python file 🌳 Package = A collection of modules (organized in folders) 🌲 Library = A collection of packages built for specific tasks 💡 Think of it like this: Module = Seed | Package = Tree | Library = Forest Once you understand this structure, reading and building Python projects becomes much easier 🚀 Keep learning.

“𝑺𝒐𝒎𝒆 𝒐𝒇 𝒕𝒉𝒆 𝒔𝒊𝒎𝒑𝒍𝒆𝒔𝒕 𝒄𝒐𝒏𝒄𝒆𝒑𝒕𝒔 𝒊𝒏 𝑷𝒚𝒕𝒉𝒐𝒏 𝒉𝒂𝒗𝒆 𝒕𝒉𝒆 𝒃𝒊𝒈𝒈𝒆𝒔𝒕 𝒊𝒎𝒑𝒂𝒄𝒕.” Today I explored an important concept in Python that clarified many doubts for me: 𝐌𝐮𝐭𝐚𝐛𝐥𝐞 𝐯𝐬 𝐈𝐦𝐦𝐮𝐭𝐚𝐛𝐥𝐞 𝐝𝐚𝐭𝐚𝐭𝐲𝐩𝐞𝐬 At a basic level: 🔹 𝐈𝐦𝐦𝐮𝐭𝐚𝐛𝐥𝐞 𝐭𝐲𝐩𝐞𝐬 (cannot be changed after creation) Examples: int, float, string, tuple → Any modification creates a new object 🔹 𝐌𝐮𝐭𝐚𝐛𝐥𝐞 𝐭𝐲𝐩𝐞𝐬 (can be modified in place) Examples: list, dictionary, set → Changes happen within the same object --- One key insight I found interesting: Multiple variables can reference the same object in memory (for mutable types). So modifying one reference can impact others as well. --- Day 3 of my journey into Python and Machine Learning 🚀 What core programming concept helped you the most early in your journey? #Python #MachineLearning #Programming #Learning #AI

Today’s Class: Mastering Lists in Python In today’s session, I explored important concepts of Python lists that are essential for efficient programming 💡 🔹 id() Function Returns the unique memory address of an object 👉 Useful to check object identity 🔹 Aliasing Two variables refer to the same list (same memory) 👉 Any change reflects in both 🔹 Cloning Creates a separate copy (different memory) 👉 Changes do NOT affect the original list 💡 Ways to Clone a List ✔️ Using copy() ✔️ Using slicing [:] ✔️ Using concatenation + ✔️ Using multiplication * ✔️ Using list comprehension ⚡ Additional Concepts 🔸 Concatenation (+) → Combine lists 🔸 Multiplication (*) → Repeat elements 🔸 List Comprehension → Efficient & readable way to create lists Global Quest Technologies #Python #DataStructures #Programming #LearnPython #Coding #PythonDeveloper #TechLearning

📘 Python Learning – Day 3 Highlights 🐍 Today’s class was all about Strings & Conditional Logic — very practical and fun! 🔹 String Methods: Used functions like lower(), upper(), strip(), replace(), find(), count(), and split() 🔹 String Formatting: Learned modern and clean way using f-strings 🔹 Conditional Statements: if, elif, else to make decisions in programs 🔹 Ternary Operator: Short and smart way to write conditions in one line 🔹 Practice Programs: ✔ Grade calculation system ✔ Palindrome checker ✔ Vowel counter 💡 Example: text == text[::-1] → checks palindrome Learning how to think logically with code step by step 🚀 #Python #Programming #Coding #LearningJourney #Beginner #TechSkills

🚀 30 𝐃𝐚𝐲𝐬 𝐨𝐟 𝐏𝐲𝐭𝐡𝐨𝐧 — 𝐃𝐚𝐲 #20 | 𝐃𝐞𝐞𝐩 𝐃𝐢𝐯𝐞 𝐢𝐧𝐭𝐨 𝐒𝐭𝐫𝐢𝐧𝐠𝐬 & 𝐌𝐞𝐭𝐡𝐨𝐝𝐬 Day 20 was all about going deeper into strings and string methods to build a stronger conceptual understanding. Instead of practicing questions, I focused on understanding how strings work internally and how different methods can be used to manipulate text efficiently. 📌 𝐖𝐡𝐚𝐭 𝐈 𝐂𝐨𝐯𝐞𝐫𝐞𝐝: 🔹 Strengthened my understanding of strings 🔹 𝐬𝐩𝐥𝐢𝐭() — breaking strings into parts 🔹 𝐣𝐨𝐢𝐧() — combining elements into a string 🔹 𝐟𝐢𝐧𝐝() — locating substrings 🔹 𝐫𝐞𝐩𝐥𝐚𝐜𝐞() — modifying text 🔹 Explored multiple other useful 𝐬𝐭𝐫𝐢𝐧𝐠 𝐦𝐞𝐭𝐡𝐨𝐝𝐬 This deeper dive helped me understand how Python handles text data and how these methods are used in real-world scenarios. 💡 𝑲𝒆𝒚 𝑻𝒂𝒌𝒆𝒂𝒘𝒂𝒚 Going deep into concepts builds clarity. When the foundation is strong, applying it becomes much easier and more effective.

DAY-12 PYTHON SERIES What is Polymorphism? Polymorphism means “many forms.” In Python, it allows the same function or method to behave differently depending on the object or context. 🔹 Why is it useful? ✔ Makes code flexible and reusable. ✔ Improves readability. ✔ Allows different classes to use the same method name. 🔹 Example in Python: class Dog: def sound(self): print("Dog barks") class Cat: def sound(self): print("Cat meows") for animal in (Dog(), Cat()): animal.sound() 🔹 Real-world example: A person can be a student, employee, or teacher — same person, different roles. 💡 Key Idea: Same method name, different implementations. #Python #OOP #Polymorphism #Coding #Programming #LearnPython #Developer #SoftwareEngineering #100DaysOfCode #Tech

From basic math ➕ to smart logic 🧠, Python operators are the building blocks of every program. ✔ Arithmetic → Perform calculations ✔ Relational → Compare values ✔ Logical → Make decisions ✔ Assignment → Store & update data ✔ Membership → Check presence ✔ Identity → Compare objects ✔ Bitwise → Work at binary level Learn these, and you’re already thinking like a programmer 🚀 #Python #Coding #Programming #LearnPython #DataAnalytics

🚀 Day 14 – Sort a List Without Using sort() (Python) 💻 Today’s task: Sort a list without using the built-in sort() function. 🔍 Explored alternative approaches: • Using lambda functions 🧠 • Using slicing techniques 🔪 📌 This exercise helped me understand: • Custom sorting logic ⚙️ • How Python handles data manipulation internally 🔍 • Writing optimized and flexible code ✨ ✨ Challenging myself to go beyond built-in functions and strengthen problem-solving skills. 📈 Consistency is key — learning something new every day. #Python #100DaysOfCode #CodingJourney #Programming #ProblemSolving #Developer #LearnToCode #Tech #PythonTips
