🪜 Generators vs Iterators While learning Python, I came across two interesting concepts: Iterators and Generators. These concepts are very useful when working with large data. 🔹 Iterator An iterator is an object that allows you to go through elements one by one. It follows two methods: • "__iter__()" – returns the iterator object • "__next__()" – returns the next element Example: numbers = [10, 20, 30] it = iter(numbers) print(next(it)) print(next(it)) print(next(it)) 🔹 Generator A generator is a simpler way to create an iterator using the yield keyword. It produces values one at a time, which helps save memory. Example: def numbers(n): for i in range(n): yield i for value in numbers(5): print(value) 💡 Key Differences ✔ Iterators require a class with "__iter__()" and "__next__()" methods ✔ Generators use the "yield" keyword ✔ Generators are more memory efficient Why are Generators important? They are useful when working with: • Large datasets • File processing • Streaming data #Python #PythonProgramming #LearningPython #Generators #Iterators #SoftwareDevelopment #CodingJourney

I’ve just published my first blog post on Medium, diving into a Python concept I recently explored: 👉 Mutable vs Immutable Objects Before this, I used to think variables simply “store values.” But in Python, they actually reference objects in memory. Having learned C previously really helped me grasp this concept more quickly, especially when it comes to understanding how memory and references work. In this post, I break down: • The difference between == and is • Mutable vs immutable objects (with clear examples) • Why l1 = l1 + [4] and l1 += [4] behave differently • How Python passes arguments to functions Writing about what I learn pushes me to go deeper and truly understand the concepts. If you’re learning Python or preparing for technical interviews, this is definitely a topic worth mastering. 📖 Read here: https://lnkd.in/guVnYN3Q #Python #SoftwareEngineering #Programming #LearningJourney #Tech

There are multiple data types in Python, and it's pivotal to understand them so that you can build Python skills from the ground up. Here is a cheat sheet that lists the most commonly used types, what they are, and an example of what their output would look like: - String: Text data that is wrapped in quotes (e.g. "Hello World" or 'Hello World') - Integer: Positive or negative whole numbers (e.g. 15, -15) - Float: Positive or negative decimal numbers (e.g. 3.14, -1.5) - Boolean: Used for true or false evaluation (e.g. True or False) - List: Ordered, mutable collection of values held within []. Allows duplicates (e.g. [1,2,2,3]) - Tuple: Ordered, immutable collection of values held within () that cannot be changed after creation. Allows duplicates (e.g. (1,2,2,3)) - Set: Unordered, mutable collection of values held within {}. Values are unique and immutable within the set itself (e.g. {1,2,3}) - Dictionary: Key-value pairs where the key is a unique identifier for the value, held within {} (e.g. {"name":"John","age":25}) The application for the different data types is endless, such as converting a list to a set in order to remove duplicates and store a unique set of values from the original list. For example: og_list = [1,2,2,3,4,4,5] new_set = set(og_list) print(new_set) # Output: {1, 2, 3, 4, 5} Once you are familiar with the different data types, you have a foundation that helps you move on to creating more advanced scripts! #Python #PythonTips #LearnPython #Programming #DataEngineering #DataScience #AnalyticsEngineering

🧠 Python Concept: set() for Removing Duplicates ✨ Sometimes lists contain repeated values. ✨ Python provides a simple way to remove them. Example numbers = [1, 2, 2, 3, 4, 4, 5] unique_numbers = list(set(numbers)) print(unique_numbers) Output [1, 2, 3, 4, 5] 🧠 What Happens? set() stores only unique values, so duplicates automatically disappear. 🧒 Simple Explanation 🍎 Imagine a basket of fruits 🍎 If you put two apples in a set basket, only one apple remains. ⚠️ Important Note set() does not preserve order. If order matters: numbers = [1, 2, 2, 3, 4, 4, 5] unique_numbers = list(dict.fromkeys(numbers)) print(unique_numbers) Output [1, 2, 3, 4, 5] 💡 Why This Matters ✔ Removes duplicates easily ✔ Cleaner data processing ✔ Very common in data handling ✔ Simple and Pythonic 🐍 Python often gives you simple tools for common problems 🐍 set() is one of the easiest ways to remove duplicates from a list. #Python #PythonTips #PythonTricks #AdvancedPython #CleanCode #LearnPython #Programming #DeveloperLife #DailyCoding #100DaysOfCode

Day 9: Python Functions as First-Class Citizens ⚙️ Mastering neat, organized code is critical for Machine Learning pipelines. Today, I did a deep dive into Python Functions, focusing on how to organize code and how Python uses computer memory: Functional Programming: Functions behave like regular data (numbers or strings). I practiced storing them in variables, giving them as inputs to other functions, and having functions create new functions. This makes processing data in steps much easier. Decomposition & Abstraction: Moving past one giant block of code to build separate "boxes" for specific tasks (like separate sections for loading data, cleaning it, and training the AI model). I focused on writing clear instructions (docstrings) inside each one. Scoping & Frame Stack: Learned exactly how Python keeps track of where variables "live." A variable created inside a function is kept separate from variables outside, preventing accidental mistakes and data mix-ups. ⚡ Arbitrary Arguments (*args): Used *args to create super flexible functions that can accept any amount of inputs. This is crucial when you don't know exactly how much data you will get, ensuring the script doesn't crash. Moving from code that "works" to code that is neat, well-documented, and ready for production. 📈 #Python #LearningInPublic #ArtificialIntelligence #SoftwareEngineering #DataPipelines #Modularity #100DaysOfCode

Most people still debate Python vs R. In real projects, that’s the wrong question. At Sankhya, we don’t choose one we use both 👇 • Python→ data pipelines, ML models, APIs, deployment • R→ statistical modeling, deep analysis, dashboards, reporting And today, they integrate seamlessly: • reticulate → run Python inside R • rpy2 → run R inside Python Here’s what this looks like in practice: Clean data in Python → Model & analyze in R → Deploy back in Python No friction. Just flow. So the mindset shifts: Not Python vs R But Python + R 👉 Right tool for the right stage 👉 Focus on the problem, not the language Because the real edge isn’t the language you pick it’s how well you combine them. #DataScience #Python #RStats #Analytics #MachineLearning #Sankhya

Day 2 of learning Pandas for Data Analysis 📊 Today I practiced how to read a CSV file using Pandas in Python. In most data analysis projects, datasets are usually stored in CSV (Comma Separated Values) format, so learning how to load them into Python is one of the first and most important steps. In Pandas, we use the read_csv() function to read a CSV file and convert it into a DataFrame. Simply put, read_csv() reads data from a CSV file and loads it into a table-like structure (DataFrame) so that we can easily explore and analyze it. While practicing this, I also learned: • head() – shows the first few rows of the dataset • tail() – shows the last few rows • shape – tells the number of rows and columns in the dataset • describe() – gives summary statistics like count, mean, min, max, etc. These functions help in quickly understanding the dataset before starting deeper analysis. Here’s the small example I tried: #Python #Pandas #DataAnalytics #LearningInPublic #DataAnalysis
