When should I use list comprehensions in Python?

List comprehensions are great for creating lists in a concise way. You should use them when you want to generate a new list by applying an expression to each item in an iterable.

Can you give me an example of a list comprehension?

Sure! For instance, if you want to create a list of squares for numbers 0 to 9, you can use: squares = [x**2 for x in range(10)].

Are there any situations where I shouldn't use them?

Yes, if the logic is too complex or if it makes the code less readable, it's better to use a regular for loop.

What about performance? Are list comprehensions faster?

Generally, yes! List comprehensions are often faster than using a for loop because they are optimized for performance in Python.
