# Why ‘yield’ can make your Python code faster — And this problem gets worse the more data we deal with. What if there are 1000 people in the line? The ‘return’ keyword def add10(x): return x + 10 x = add10(4) # x = 14 def get_takoballs(orders): output = [] for order in orders: output.append(f'{order} takoballs')…

# Stuff I wish I learnt earlier as a beginner — There are lots of concepts we need to grasp in Python. And everyone learns them differently, in different sequences. Here are some things I wish I learnt much earlier when I was still a Python beginner. 1) Tuple Unpacking + Tuple Unpacking With * person = ['bob', 30, 'male'] name, age, gender = person # name='bob, age=30, gender='male' …

# this list keeps getting longer — 1) We can set variables dynamically using globals() a = 4 b = 5 ^ this is the same as: globals()['a'] = 4 globals()['b'] = 5 globals() is a dictionary containing all global variables, and we can set variables by add key-value pairs into globals(). (don’t do this in production code tho) 2) re.sub can take in functions # replacing vowels with - import re x…

In simple terms, web scraping refers to extracting data from websites automatically. It’s like going to a website, and copying down the data — just that we use Python (or whatever language) to make this automatic. What is Beautiful Soup? Beautiful Soup is a Python library that is commonly used for web scraping. It…

# A Short Introduction To Concurrency In Python — Asynchronous programming is a programming paradigm that allows for non-blocking I/O operations, resulting in more efficient and faster code execution. In Python, the asyncio module provides a framework for asynchronous programming. Here, we will discuss what asyncio is, how it works, and how to use it in Python. What is AsyncIO? AsyncIO is…

1) Basic List Comprehension lis = [1, 2, 3, 4, 5] new = [n**2 for n in lis] # new = [1, 4, 9, 16, 25] Here, our list comprehension generates a new list containing the squares of each number in the original list lis. 2) List Comprehension With A Condition lis = [1, 2, 3, 4, 5] new = [n**2…

When working with Python functions, you may come across the terms global and nonlocal. These two keywords are used to define the scope of variables in Python. Here, we will explore the differences between global and nonlocal variables, how they are used, and when to use them. Global Variables A global variable…

# I Love Python, But… — Python is probably my favourite language. As people say: There are only 2 kinds of programming languages — the ones people complain about and the ones nobody uses. Python is not perfect, and there are still stuff about it that I would do away with in a heartbeat if I…

# Don’t Use This To Blame Your Teammates — One of the less-known but incredibly useful features of Git is the git blame command. Here, we will take a deep dive into the world of git blame, exploring its functionality, use cases, and tips for using it effectively. What Is Git Blame? git blame is a command that helps developers trace the history…
