How can I use itertools with lambda functions?

You can use itertools to create iterators for efficient looping, and lambda functions can be used to define small anonymous functions. For example, you can use itertools.map with a lambda to apply a function to each item in an iterable.

Can you give me a code example?

Sure! Here's a simple example:

import itertools

numbers = [1, 2, 3, 4]
result = itertools.map(lambda x: x * 2, numbers)
print(list(result))  # Output: [2, 4, 6, 8]

What other itertools functions can I use with lambda?

You can use itertools.filter to filter items, itertools.starmap for multiple arguments, and itertools.reduce for cumulative operations. Each can work well with lambda functions!

Are there any performance benefits to using itertools?

Yes, itertools is designed for efficient looping and can handle large datasets without loading everything into memory at once, which can significantly improve performance.
