Power of Two

Why use the (True, False)[n%2==0] format, this structure in Python is much easier on the eye, at least in my opinion.

Code
Diff
  • power_of_two = lambda n: False if n%2 else True
    • power_of_two = lambda n: (False, True)[n % 2 == 0]
    • power_of_two = lambda n: False if n%2 else True

Function that adds the digits of an integer

Code
Diff
  • def digit_sum(number: int) -> int:
    return sum([int(num) for num in str(number) if num.isdigit()])
    • def digit_sum(number: int) -> int:
    • return sum(map(int,list(str(abs(number)))))
    • return sum([int(num) for num in str(number) if num.isdigit()])
