A quick demonstration of why sometimes using yield is better and can make your code run faster (especially when dealing with lots of data). — When we started learning Python, we were probably taught to use the return keyword in functions rather than yield. In this article, I’ll quickly demonstrate why sometimes using yield is better and can make your code run faster (especially when dealing with lots of data).

A guide on creating a class in Python without using the ‘class’ keyword. — Disclaimer — You probably won’t ever see this in real code. But messing around with code is fun, so let’s explore how we can define a class without using the class keyword. A Normal Dog Class class Dog: def __init__(self, name, age): self.name = name self.age = age def bark(self): print(f"Dog(name={self.name}, age={self.age}): woof")

A guide on how to replace outliers in Python. — When performing data processing, we need to do something to outliers to protect our model from being completely screwed up. Here’s a simple Python code snippet that allows you to do just that. Our Dummy Dataset data = pd.DataFrame([ [87, 82, 85], [81, 89, 75]…

Being able to write code in one line probably won’t guarantee you a high-paying tech job, but it sure does feel satisfying. Here are thus 5 Python questions that can usually be easily solved under normal circumstances. The catch — you need to solve it in one line of code. 1. Checking If A Number Is Prime …
