Python Data Structures: Lists, Tuples, Dictionaries

🚀 Python Variables Explained (Beginner Friendly) Today I practiced Python variables and naming conventions 1. Basic Variable Declaration name = "Ankaj" age = 36 salary = 50000 print("Name:", name) print("Age:", age) print("Salary:", salary) 2. Variable Naming Rules user_name = "Ankaj" age1 = 25 _salary = 30000 print(user_name) print(age1) print(_salary) 3. Constants Convention (Uppercase) PI = 3.14 MAX_SPEED = 120 COMPANY_NAME = "ABC Pvt Ltd" print(PI) print(MAX_SPEED) print(COMPANY_NAME) Key Learnings: * Variables store data values * Naming rules matter in clean code * Constants are written in UPPERCASE by convention I’m building my Python skills step by step Follow Ankaj Python Hub for my daily learning journey #Python #Coding #LearnPython #100DaysOfCode #Programming

🐍 Python Tip 5: Use set() to remove duplicates from a list Sometimes while working with data, we may have duplicate values in a list. Instead of writing extra logic, Python provides a simple way: numbers = [1, 2, 2, 3, 4, 4, 5] unique_numbers = list(set(numbers)) print(unique_numbers) Output: [1, 2, 3, 4, 5] Why this is useful? • Quick way to remove duplicates • Very helpful in data preprocessing • Saves time and keeps code simple Small tricks like this make working with data much easier. Note: This does not preserve order. If order matters, a different approach is needed. #Python #PythonTips #DataScience #CodingTips #Programming #LearnPython

Let's now talk about Variables in Python. What is a variable? Think of it like a box, you give it a name and store a value inside it. Example: a = 10 name = 'Alice' price = 19.99 Here, a, name, price are all variables in which we have stored some value or data. Simple right? But here's where most beginners make mistakes- naming their variables wrong. There are 3 conventions you need to follow: 1️⃣ First letter should be lowercase (best practice as per PEP8) 2️⃣ Never start a variable name with a number 3️⃣ Never use spaces, use an underscore instead Break any of these and Python will throw an error before your code even runs. Get these right from day one and you'll save yourself a lot of frustration later. #Python #DataAnalytics #data #python #learnpython #dataanalyst #pythonforbeginners

🚀 Automated My Downloads Folder Using Python Today, I built a simple yet useful File Organizer script using Python that automatically sorts files into folders. We often download many files, and our Downloads folder becomes messy. So I created a script to organize it automatically 👇 ✨ What This Script Does • Scans all files in the Downloads folder • Moves .jpg files into an Images folder • Moves .pdf files into a PDFs folder • Helps keep files clean and organized ⚙️ Technologies Used • Python • os module (for file handling) • shutil module (for moving files) 🧠 What I Learned • Working with file systems in Python • Automating real-world tasks • Writing efficient and reusable scripts • Importance of automation in daily life 💡 Key Insight Even small automation scripts can save time and improve productivity. If you have suggestions to improve this script (like handling more file types), I’d love to hear them! 😊 #Python #Automation #Programming #LearningInPublic #DeveloperJourney #Productivity #10000Coders #BuildInPublic

Today I want to share what I learned about #Python3 #TypeAnnotations. Python 3 introduced the PEP 3107-style annotations by enabling type annotations. https://lnkd.in/eBvhxWsQ Python 2 lacks a way to annotate a function's parameters and return values. This also means that you can have expressions that have an assignable type to the annotated return type in the function. For a high level language like Python 3, this is great since you can easily enforce the type of data that travels through your code! Another neat thing is within the editor for auto complete, you can use methods for variables in your code! #Python #Py #TypeHints #OOP #ObjectOrientedProgramming #CS #ComputerScience #SWE #SoftwareEngineer #SDE #SoftwareDevloper

🔢 Python Program: Even/Odd Checker ```python numbers = [10, 15, 20, 25] for num in numbers: if num % 2 == 0: print(num, "Even") else: print(num, "Odd") ``` 💡 Use case: ✔ Data filtering ✔ Log classification #Python #Programming

📅 Day 4 – Python Sets 🐍 Today I learned one of the most useful concepts in Python – Sets and practiced different operations on them 👇 🧠 What is a Set? A set is a collection of unique elements stored in a single variable. It does not allow duplicates and does not follow any specific order. 📚 What I learned: • Sets are unordered and mutable • Duplicate values are automatically removed • Useful for storing unique data • Fast operations compared to lists 🔄 Operations I practiced: • Union → combine sets • Intersection → common elements • Difference → unique elements from one set • Symmetric Difference → uncommon elements 📸 I practiced these operations with small programs (screenshots attached 👇) Sets are very helpful when working with unique values and performing mathematical operations efficiently. Consistent daily practice is helping me improve step by step 💪 #Python #100DaysOfCode #CodingJourney #LearningPython #Developers

🔁 Python Program: Fibonacci Series ```python n = 6 a, b = 0, 1 for _ in range(n): print(a) a, b = b, a + b ``` 💡 Builds strong logic thinking #Python #Logic
