Question

I like Python for it’s expressiveness. I can’t express everything as compact as I’d like to, though. For example this one I write quite often:

  def is_everything_okay(some_array):
    for s in some_array:
      if not is_okay(s):
        return False
    return True

But that’s more Java then Python. How to improve the expressiveness (and probably execution speed) of that code snippet?

Answer 1

Use the built-in function all():

all(is_okay(s) for s in some_array)
