How does list comprehension performance compare to traditional loops in Python?

List comprehensions are generally faster than traditional for loops in Python because they are optimized for performance.

Can you provide an example to illustrate the difference?

Sure! Here's a simple example:

Using a for loop:

result = []
for i in range(1000):
    result.append(i * 2)

Using list comprehension:

result = [i * 2 for i in range(1000)]

The list comprehension is more concise and often faster.

What factors affect the performance of list comprehensions?

Factors include the complexity of the operation inside the comprehension, the size of the input data, and Python's internal optimizations.

Are there any scenarios where traditional loops might be better?

Yes, if you need to perform complex operations that involve multiple steps or if readability is a priority, traditional loops might be better.
