List Comprehensions: For Loops' Glow-Up 💫

#python#coding#softwaredevelopment#tutorial

For loops? They're giving... 2016. List comprehensions are the glow-up we needed. They're shorter, faster, and honestly, just more main character energy. 😎

Turn this whole saga:

squares = []
for x in range(10):
    squares.append(x**2)

Into this iconic one-liner:

squares = [x**2 for x in range(10)]  # Clean. Elegant. Powerful. 😮💨

But wait, there's more! You can add filters. Only even squares? No sweat.

even_squares = [x**2 for x in range(10) if x % 2 == 0]  # She's beautiful 😍

It's like a for loop and an if statement had a baby and it was perfect. You can even do nested loops (but keep it readable, no cap 🧢).

Use them. Live them. Your code will thank you. Periodt. ✨
