input: Write a function to determine whether a given number is even or odd. If the number is even, return "Even", otherwise return "Odd".
  assert even_or_odd(4) == "Even"
  assert even_or_odd(7) == "Odd"
  assert even_or_odd(0) == "Even"
  assert even_or_odd(-3) == "Odd"
  assert even_or_odd(-10) == "Even"
output: def even_or_odd(number):
      if number % 2 == 0:
          return "Even"
      else:
          return "Odd"
