How can I combine itertools and map in Python?

You can use itertools to create iterators and then apply the map function to transform the data. Would you like an example?

Yes, please provide an example.

Sure! Here's a simple example:

import itertools

# Create an iterator using itertools
numbers = itertools.count(1)

# Use map to square the first 5 numbers
squared_numbers = list(map(lambda x: x**2, itertools.islice(numbers, 5)))
print(squared_numbers)  # Output: [1, 4, 9, 16, 25]

What does itertools.islice do in this example?

itertools.islice allows you to slice an iterator, so in this case, it takes the first 5 numbers from the infinite count iterator.
