3x Faster: Ditch `map()`

Quick Tip: List comprehensions are faster than map() in most cases

When it comes to transforming iterables in Python, two popular options are list comprehensions and the map() function. While both can achieve the same result, they differ in terms of performance. In most cases, list comprehensions are faster than map().

Let's take a quick look at a simple example using the timeit module to benchmark the performance of both approaches:

python
import timeit

# Define a simple function to square a number
def square(x):
    return x ** 2

# Create a list of numbers
numbers = list(range(1000))

# List comprehension
list_comp = timeit.timeit(lambda:
