Python Sets are heavily used in Data Science, Data Cleaning, NLP, Feature Engineering, and real-world analytics problems. If you’re still using lists everywhere, this video will change how you write Python code. 🔥 What You Will Learn in This Video (Day 14 – Sets in Python) ✅ What is a Set? Unique elements Unordered structure Why sets are faster for membership checks ✅ Creating Sets (Different Ways) Using {} Using set() Converting lists and strings to sets ✅ Key Characteristics of Sets Unique values Mutable structure No indexing (and why that’s important) ✅ Adding & Removing Elements add() update() remove() vs discard() pop() and clear() ✅ Membership Testing Using in and not in (VERY fast operations) ✅ Set Operations (Very Important) Union Intersection Difference Symmetric Difference ✅ Advanced Set Concepts Subset & Superset Disjoint sets Copying sets Frozen sets (immutable sets) ✅ Real Data Science Use Cases Removing duplicates from data Comparing features between datasets Unique tokens in NLP Feature overlap analysis JSON-style data handling 🔗 Resources & Links 📘 Notebook / Code Files: https://drive.google.com/drive/folder... 🎯 Why Sets Are Important for Data Science? Sets help you: Clean data efficiently Remove duplicates instantly Perform fast comparisons Handle large datasets better Simplify NLP and feature engineering logic Mastering sets makes your Python code cleaner, faster, and more professional. ▶️ Watch Previous Days (Full Playlist) 📌 Day 1 – VS Code Installation 📌 Day 2 – Python Basics [   • How to Install VS Code for Python (Step-by...  ] 📌 Day 3 – Data Structures + Libraries [    • Day 2: Python Basics for Data Science (Beg...   ] 📌 Day 4 – If–Elif–Else Conditions [    • Day 3: Python Data Structures, NumPy & Pan...   ] 📌 Day 5 – For Loop [    • Day 4: Python If–Elif–Else Explained for D...   ] 📌 Day 6 – For Loop Advance [    • Day 6 : Python For Loop SECRET You Need to...   ] 📌 Day 7 – Full While Loop Masterclass [    • Day 7: While Loop Mastery for Data Science...   ] 📌 Day 8 – Functions 📌 Day 9 – List Basics 📌 Day 10 – Advanced Lists 📌 Day 11 – Tuples 📌 Day 12 – Dictionaries (Basics) 📌 Day 13 – Advanced Dictionaries 📌 Day 14 – Python Sets 🎥 Full Playlist: [    • 120 Day Data Science Series   ] 🔗 Follow Me on Socials 📸 Instagram:   / datascientistafzal.ai   💼 LinkedIn:   / afzal-mansury   📢 WhatsApp Channel: https://whatsapp.com/channel/0029VaCL... 🌐 TopMate (Ask me Anything): https://topmate.io/dashboard/home 🎥 Gear & Products I Use (Affiliate Links) 🎙️ Hollyland Lark M2 Combo : https://amzn.to/4nqWpst 💡 Digitek Ring Light : https://amzn.to/4oLDauW 📷 Digitek Tripod : https://amzn.to/43BjscY 💻 My Laptop Lenovo LOQ 2025 AMD Ryzen 7 250| NVIDIA RTX 5050 8GB : https://amzn.to/4ocqbCp 🎬 My Gaming Chair: https://amzn.to/4qAYrsI python dictionary basics, python dictionary tutorial, nested dictionary python, python for data science, python data structures, dictionary methods python, 120 day data science series, python beginner to advanced, python key value pairs, python interview preparation, Other Title “Day 2: Essential Python for Data Science | Variables, Loops, Functions | 120-Day Series, “Day 3: Python Data Structures, NumPy & Pandas Basics | 120-Day Data Science Series”, “Python Data Structures for Data Science (Lists, Tuples, Dicts) | Day 3 of 120-Day DS Series”, “Day 3: Python Data Structures + NumPy, Pandas & EDA Basics | Data Science Series (120 Days)”, “Learn Python Data Structures for Data Science | Day 3: NumPy, Pandas, NLP Basics”, “Python for Data Science – Day 3: Data Structures, NumPy, Pandas, Matplotlib (120-Day Series)”, “Day 3: Essential Python Data Structures for Data Science | NumPy & Pandas Explained”, “Python Data Structures & NumPy/Pandas Basics | Day 3 of Data Science Series”, “Day 5: Python For Loop Explained for Data Science | 120-Day Data Science Series”, “Python For Loop Tutorial for Beginners | Day 5 of 120-Day Data Science Series”, “Python For Loop: Range, Enumerate, Nested Loops & More | Day 5 Data Science Series”, “Learn Python For Loop Step-by-Step | Day 5: Data Science for Beginners”, “Python For Loop Basics to Advanced (Range, Break, Continue, Nested) | Day 5”, “Python Loops for Data Science – For Loop Explained | Day 5 of 120 Days", “Day 5: Python For Loop Made Easy | Data Science Series”
