Use Next¶
Sourcery refactoring id: use-next
¶
Description¶
Use the built-in function
next
instead of a
for-loop.
Before¶
def get_first_even_number(numbers):
for number in numbers:
if number % 2 == 0:
return number
return None
After¶
def get_first_even_number(numbers):
return next((number for number in numbers if number % 2 == 0), None)
Explanation¶
When choosing the first item from an iterable that passes a condition, we can
use the next
built-in function instead of a for-loop to make our code and our
intent clearer.
