Finally on python. Import all Libraries Load your dataset Carry out exploratory data analysis and Check for null values (drop colums or replace them) Visualize your data and check correlations (depending on the algorithm you adopt) Declare X and Y values Split x and y into training or test set Train our data and fit them Make your predictions Test how accurate your prediction is Then Display your report If you are using Decision tree : Visualize your decision tree Create a list of feature and class names for better readability Plot your tree. Fun working with python. Full practise starts now Kaggle, here i come.

Python Daily Tip #1 Python uses indentation to define code blocks, not braces {}. This will raise an error: if x > 0: print("Positive") This works: if x > 0: print("Positive") Why? Indentation is part of Python’s syntax, not just a formatting convention. If you’re coming from Java or Kotlin, think of indentation as mandatory braces.

🐍📰 Custom Python Dictionaries: Inheriting From dict vs UserDict In this tutorial, you'll learn to create custom dictionary-like classes in Python by inheriting from the built-in dict class or by subclassing UserDict from the collections module #python

🚀 Python OOPS – Day 7 🔧 __init__() Method (Constructor in Python) The __init__() method is Python’s constructor, automatically executed when an object of a class is created. Its main purpose is to initialize instance attributes and prepare the object for use. In simple terms: ➡ Class = Blueprint ➡ Object = Actual instance ➡ Constructor = Sets initial values inside the object The method takes self as its first parameter, representing the specific instance being created. 📝 Key Highlights ✔ Called automatically during object creation ✔ Initializes attributes with default or custom values ✔ Makes objects ready for immediate use Example use cases: 🎯 student registration, 🎯 user account creation, 🎯 order processing—all require initialization at the moment of creation.

Hey fellow Python devs! Hit the Python 3.14+ PicklingError with multiprocessing lambdas? I made a one-line fix: ```python import mp_compat ``` That's it! Auto-detects version, applies the fix, zero refactoring needed. https://lnkd.in/d8ea62hB Hope this saves someone a few hours of debugging! #Python #Python314 #Multiprocessing #PicklingError

🐍 The Zen of Python: a set of guiding principles for writing good Python code. What happens when you run `import this` in Python shell? You will see the Zen of Python, a set of simple but powerful principles that guide how good Python code should be written. It is not about syntax. It is about clarity, simplicity, and thoughtful design. If you believe, code should be easy to read and understand, then the Zen of Python is for you! #Python #ZenOfPython #CodeQuality #CleanCode #ProgrammingPrinciples #DeveloperTips

Hate me for saying this, but most Python developers don’t actually know what 𝗶𝗳 __𝗻𝗮𝗺𝗲__ == "__𝗺𝗮𝗶𝗻__" does in their codebase. In simple words, it tells Python "run this code only when this file is executed directly as a single script, not when it’s imported somewhere else." So if you run the file with python file.py it will assign __name__ variable with __main__ keyword and which runs the code inside it. But if you are importing it as a module it will assign __name__ variable as the file's name which make the if condition false. #python #main #fastapi
