What is the difference between list comprehension and for loops in Python?

List comprehension is a concise way to create lists in Python, while for loops are more verbose. List comprehensions can be faster and more readable for simple tasks.

Can you give me an example of both?

Sure! For a list of squares:

Using a for loop:

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

Using list comprehension:

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

When should I use one over the other?

Use list comprehension for simple transformations and when you want cleaner code. Use for loops when the logic is more complex or involves multiple steps.

Are there any performance differences?

Yes, list comprehensions are generally faster than for loops because they are optimized for performance in Python.
