Learning Python: Custom Functions with Datacamp

🐍 Learning Python – Day 1 : Getting Back to the Basics Today I spent some time revisiting the fundamentals of Python, and honestly, it reminded me why this language is loved by beginners and professionals alike. The syntax is clean, the concepts are easy to grasp, and everything just feels… logical. Here’s what I explored today 👇 🔸 1. Introduction to Python I started with the basics — understanding what makes Python such a popular language. It’s versatile (used in web apps, automation, AI, data science), and the best part is that the code feels very close to English. That simplicity is what makes it powerful. 🔸 2. Input & Output I refreshed how Python interacts with users: ◾ input() helps you take data from someone using the program ◾print() displays information back to the user It seems simple, but this is the foundation of how any program communicates. 🔸 3. Variables I revisited how variables act like little boxes where we store information. What I like about Python is that you don’t need to mention the data type — just assign a value and Python understands it automatically. Example: name = "Riya" age = 21 🔸 4. Data Types I explored the main data types again: ◾ Integers → whole numbers ◾ Strings → text (my favourite to work with 😄) ◾ Float → decimal numbers ◾ Boolean → True/False values ◾ None → represents “nothing” or an empty state Understanding these helped me see how Python handles different kinds of real-world data. 🔸 5. Operators Then I went through Python operators — things like +, -, *, / for arithmetic, and even comparison operators like >, <, ==, which help make decisions in the code. These small building blocks are what eventually help us write logic that solves real problems. ✨ Overall, it felt good to slow down and strengthen my basics. Sometimes revisiting foundational topics gives so much clarity — especially when preparing for larger projects or interviews. If anyone else is learning Python or wants to, feel free to connect.

Introduction to Python: History and the Story Behind Its Name Python is a powerful, high-level programming language known for its simplicity, readability, and versatility. It is widely used in web development, data science, artificial intelligence, and automation. With a vast ecosystem of libraries and a strong community, Python enables developers to build efficient, scalable, and innovative solutions with ease. Python was created by Guido van Rossum in the late 1980s at CWI (Centrum Wiskunde & Informatica) in the Netherlands. The first version, Python 0.9.0, was released in 1991, featuring functions, exceptions, and core data types like lists and strings. Over time, major updates such as Python 2.0 (2000) and Python 3.0 (2008) introduced significant improvements, making the language more consistent and modern. Today, Python stands among the most popular languages worldwide, powering technologies across diverse domains. The Story Behind the Name: Interestingly, the name Python doesn’t come from the snake. Guido van Rossum named the language after the British comedy series “Monty Python’s Flying Circus.” While developing the language, he was reading the show’s scripts and wanted a name that was short, catchy, and a little fun — just like the show’s spirit. The name reflects Python’s friendly and approachable philosophy, which continues to attract both beginners and professionals alike. #machinelearning #deeplearning #webdevelopment #artificialintelligence #automation

Python is simple — until you forget the syntax. Python is everywhere in data science, automation, AI, analytics, and even web development. But when you’re learning (or switching from another language), it’s easy to forget the syntax or mix up concepts. That’s why I put together this free resource covering everything you need to write clean, efficient Python code. Here’s what’s inside: ✅ Basic syntax, comments, and type casting ✅ Lists, tuples, sets, and dictionaries ✅ Loops, conditionals, and functions (including lambdas) ✅ File handling, error handling, and list comprehensions ✅ Libraries like NumPy, Pandas, and Matplotlib ✅ Practical examples for real-world coding 👇 Download the full Python Cheatsheet PDF below

📦 Variables and Data Types in Python - A Beginner’s Guide When I first started learning Python, I kept hearing words like variables and data types - and honestly, they sounded more complicated than they really are 😅 But once I understood them, everything else in Python started to make sense. Here’s how I like to explain it 👇 🧠 What’s a Variable? Think of a variable as a box that stores information. You give it a name, and Python remembers what’s inside. name = "Blessing" age = 20 Now, anytime you use name or age, Python knows what you mean. 🧩 Common Data Types in Python Every variable holds a type of data. Some of the most common are: # Text name = "Blessing" # str # Numbers age = 21 # int height = 5.6 # float # True/False is_student = True # bool # Collections hobbies = ["coding", "reading"] # list Each data type behaves differently - and together, they form the foundation of Python programming. 🪄 Why It Matters Variables and data types are the building blocks of every Python project - from simple scripts to data science models. They make your code flexible, readable, and powerful. And here’s the cool part... Python automatically figures out the data type for you. x = 5 # int x = "Five" # now a string Dynamic, right? 💡 Quick Tips ✅ Use descriptive variable names total_score, user_age ❌ Avoid vague ones like x1 or thing Good naming = clean, understandable code. Learning variables and data types might seem basic, but it’s truly the first real step toward thinking like a programmer. Once you get this right, Python starts to feel a lot more natural, almost like writing in plain English. 💬 What was the first variable you ever created in Python? Mine was the classic: x = 10 😂 #Python #LearningJourney #DataScience #Programming #CodeNewbie #WomenInTech

🚀 Mastering Lists in Python 🧠 Today, I explored one of the most important data structures in Python — Lists! Lists are dynamic, mutable, and versatile — making them a go-to structure for storing and manipulating data efficiently. Here’s what I covered 👇 🔹 Definition & Characteristics – Lists are ordered, mutable, and can store elements of mixed data types. 🔹 Accessing Elements – Using positive and negative indexing. 🔹 Slicing – Extracting sublists efficiently using slice notation. 🔹 Commonly Used Methods – append(), extend(), insert(), remove(), pop(), sort(), reverse(), copy() 🔹 Built-in Functions – len(), sum(), max(), min(), list(), any(), all(), etc. 🔹 Basic Programs – Covered 20+ real examples like inserting, deleting, reversing, merging, finding average, removing duplicates, etc. 🧩 Lists are the foundation for solving many coding problems — from basic logic building to complex data processing! --- 💡 Key Takeaway: Learning Lists helps you understand data manipulation, iteration, and algorithmic thinking — essential for every Python developer and problem solver. --- LogicWhile #Python #LearnCoding #PythonLists #CodingJourney #100DaysOfCode #ProblemSolving #DataStructures #PythonForBeginners #CodeWithMe #DeveloperJourney #ProgrammingBasics #LogicBuilding #TechLearning #CodingCommunity

Week 1 of Python ✅ I just wrapped up Week 1 of my Python course — and so far it’s been a strong review. Python is one of the languages that originally got me excited about coding (right alongside SQL), so it feels good to be back in it again. This week’s review included: - coding syntax & Python conventions - IDE familiarity - variables, expressions & math functions - string functions & user input - basic data types: string, int, float, list Hands-on practice so far: - number games - Mad Libs - math operations - and the classic “Hello World!” Coming up next: - the rest of the core data types: tuples, sets, dictionaries - branching logic: if/else, equality checks, ranges, conditional expressions - small practice labs: simple statistics, list/set operations, evaluating golf scores Even though I learned Python years ago, I'm noticing syntax feels cleaner and simpler now — maybe because I have more perspective, maybe because I’ve used SQL for so long. Either way… I’m enjoying it more this time around. Community question — fun one: I learned that “tuple” has two common pronunciations (just like in SQL discussions): Do you say “tuh-ple” or “too-ple”? Curious which side people lean toward! — Here’s to week 2 — and staying consistent. Picture from Samuel Ferrara @samferrara https://lnkd.in/ehYSWKqy
