Really good article. Looking forward to reading the rest of the series :) And thanks for the book recommendation, will check it out.

Just can't wait for top level await to land, really looking forward to that one

Great article. This technique is really nice for writing functional programming style code

Ooh, thats really nice

Nice. Here is another approach using functions from itertools. I really like the functions in itertools for these kinds of problems from itertools import count, takewhile def is_palindromic(num): return num == int(str(num)[::-1]) def palindromic(max_num): all_numbers = count() nums_palindrome = (num for num in all_numbers if is_palindromic(num)) return takewhile(lambda x: x < max_num, nums_palindrome) output = list(palindromic(500)) print(output) print(len(output))
