Applying NumPy to Real Data Simplifies Coding

Been learning Data Analytics for the past few months. One thing is clear: numbers aren’t optional — they are the core. Everything in analytics revolves around how efficiently you can process, manipulate, and extract meaning from data. That’s where NumPy comes in. Built on C, it’s significantly faster and more efficient than plain Python for numerical operations — often by huge margins. If you’re still relying only on Python loops, you’re doing it wrong. Sharing a quick NumPy cheat sheet I’ve been using to level up my workflow. Stop writing slow code. Start thinking in arrays. #DataAnalytics #DataScience #Python #NumPy #MachineLearning #AI #Programming #DataAnalysis #LearnDataScience #Upskilling #CareerGrowth #CodingLife #BuildInPublic

Day 5 Consistency is key! 🚀 I’ve been dedicating time to strengthening my Python fundamentals, specifically diving deep into how to work with data sequences. From understanding immutability to mastering indexing and slicing techniques, I’m building a solid foundation to handle data manipulation more effectively. It’s rewarding to see how these concepts translate into cleaner, more efficient. Today I’ve been practicing advanced sequence manipulation in Python. Key takeaways from my study session: Immutability: Understanding why certain data types (like strings) cannot be changed in place. Slicing Syntax: Mastering [start:stop] and how to omit indices for cleaner, faster code. Negative Indexing: Leveraging indexing from the end to make my code more dynamic. There is always something new to learn when it comes to optimizing data extraction! 💡 #PythonProgramming #SoftwareDevelopment #LearningToCode #DataManipulation #CodingTips #Python #CodingJourney #ContinuousLearning #DataHandling #SelfDevelopment #TechSkills

Let's Become ML Engineers Together — Phase 1: Foundation (Part-1) Python for Machine Learning There are many apps and environments where you can write and run Python code, But I would suggest Google Colab 1️⃣ Basics Variables & types— No type declarations needed. Python figures it out. Math & comparisons if / elif / else for loops 2️⃣ Data Structures List — ordered, changeable Dict — key → value pairs Tuple — immutable list Set — unique values List comprehension — compact loops 3️⃣ Functions & OOP 🌟 Defining functions Default arguments Lambda — one-line function Defining a class Inheritance 💭 You can learn from https://lnkd.in/gsYx6j8J #ML #Python #Basic

Python is more than just code; it’s a powerful calculator! 🧮 Today, while diving deeper into my Data Science journey, I spent some time mastering Python's mathematical operators. It’s not just about simple math; it's about understanding how the machine processes different operations to build solid business logic. From basic addition to Floor Division and Exponentiation, understanding these basics is crucial for building accurate data models later on at Data Hub. 📊 In this snippet: Handled different types of operations. Explored how Python handles float results vs integers. Question for the experts: What’s the most common mathematical error you faced when you first started coding? 🧐 #DataHub #Python #Coding #DataAnalysis #LearningJourney #TechCommunity

I decided to go all in on Python for data engineering. 🐍 Here's everything I've learned in just the first week: → Data types, variables & expressions → Lists, tuples, sets, and dictionaries → Conditionals, branching, and loops And in the coming week, I'll be starting the fun part — functions, classes, pandas, NumPy, and working with APIs. I used to think coding was for "technical" people. Turns out it's just logic + practice. What's one Python concept you wish you'd learned sooner? Drop it below — I'm taking notes. 👇 #Python #DataEngineering #LearningInPublic #TechCareer

My first ML project is live on GitHub. Built a Random Forest model trained on 1,460 real house sales that predicts sale prices with a Mean Absolute Error of ~$17,000. Used SHAP values to explain which features drive predictions — turns out overall quality and living area matter most. Tech used: Python, pandas, scikit-learn, SHAP https://lnkd.in/gC4DhQbg #DataScience #MachineLearning #Python #Portfolio

Day 1 — Revising Data Science fundamentals Today I revisited Python fundamentals from the very beginning: * Variables & data types * Input/Output * Type casting * Operators (arithmetic, logical, comparison) Applied these concepts by building a basic calculator program Revisiting the basics gave me more clarity than rushing ahead ever could. GitHub: https://lnkd.in/gqJkKJ36 Looking forward to staying consistent and improving every day. #DataScience #Python #LearningInPublic #Consistency

Building stronger fundamentals, one step at a time. Day-22 & Day-23 of my Data Analytics journey 🚀 Focused on reinforcing core Python concepts — • Revisiting Python basics & data types • Understanding functions and working fundamentals • Exploring how code executes in the background • Practical use cases of lists, tuples, and dictionaries Deep diving into fundamentals to write better, cleaner, and more efficient code. #DataAnalytics #Python #PythonBasics #LearningJourney #Consistency #Programming #SelfGrowth #DataAnalyst #CodingJourney #Upskilling

Most people use Pandas for EDA. 𝗩𝗲𝗿𝘆 𝗳𝗲𝘄 𝘂𝘀𝗲 𝗶𝘁 𝗲𝗳𝗳𝗶𝗰𝗶𝗲𝗻𝘁𝗹𝘆. That’s the difference between spending hours exploring data and getting insights in minutes. Over time, one thing has stood out to me: It’s not just about the insights - it’s about how efficiently you get there. I’ve put together a quick reference: 📊 10 Pandas EDA Tricks that help: • Write cleaner, more readable code • Speed up analysis • Build more reliable workflows 📌 Attached is a cheat sheet for easy reference.

Day 2 done. Today I sat down and learned about Variables and Data Types in Python. And okay... I get it now why people say "start with the basics." I used to skip this stuff. Thought it was too simple to matter. But here's what I realized today: Every single AI model, every dataset, every algorithm you see online it all starts with this. A variable is just a box where you store something. name = "Ali" age = 20 is_learning = True That's it. That's literally it. But when you understand WHAT you're storing - int, str, float, bool - suddenly your code starts making sense. I'm not where I want to be yet. But I'm not where I was yesterday either. Day 1 was print("Hello World") Day 2 is Variables & Data Types Day 3 let's see what happens. If you're also learning from scratch, just know - you're not alone. #Python #LearningInPublic #AIMLEngineering #Day2 #100DaysOfCode
