Python Dictionary Full Power! 🧠 | Loop, Methods, Comprehension & Nested Dict – Video #13

In this episode #13 of our Python Zero to Hero series, we're taking a deep dive into the world of dictionaries in Python! 🚀 Dictionaries are a fundamental data structure that allow you to store key-value pairs, making data retrieval and manipulation a breeze. We'll start by exploring the basics of dictionaries, including how to create and access them. Then, we'll move on to more advanced topics like looping through dictionaries, understanding and using built-in dictionary methods effectively, and even mastering dictionary comprehensions for concise and powerful code. Dictionary क्या होता है? 👉 Dictionary = Key-Value Pairs का Collection! जैसे: { "name": "Rahul", "score": 100, "level": 5 } यहाँ "name" → key, "Rahul" → value! और सबसे बढ़िया बात? Keys unique होती हैं, values repeat हो सकती हैं! इस वीडियो (#13) में आप सीखेंगे: ✅ Dictionary Basics: Create, access, add/update items ✅ Looping Through Dictionary:  - for key in dict:  - for key, value in dict.items(): ← ये सबसे useful है! ✅ Top Built-in Methods (IMPORTANT!):  - .keys(), .values(), .items()  - .get(key, default) ← Error नहीं देता!  - .pop(), .popitem(), .clear() ✅ Dictionary Comprehension:  - {key: value for ...} → Lists की तरह, लेकिन smarter! ✅ Nested Dictionary:  - Game में player data, student records — real examples! ✅ Common Errors & Fixes:  - ❌ KeyError: Key exist नहीं करती? → Use .get()!  - ❌ Mutable default argument mistake  - ❌ Shallow copy issue in nested dicts 🎯 Real Use Cases: Game inventory system User profile storage Config settings in apps ये video game development, data handling, और interview basics — तीनों के लिए must-watch है! 👉 खुद से try करो, error देखो, फिर solution समझो — यही coding सीखने का सही तरीका है! अगर आप Python Zero to Hero Journey में serious हैं, तो LIKE 👍, SHARE 🔄, SUBSCRIBE 🔔 ज़रूर करें!
