Your task
Write a programm that takes number as an input, and returns "Even" if number is even; "Odd" if number is odd and "Zero" if number is zero.
Note: numbers can be negative. You will need to treat negativer numbers like positive: -2 is even; -1 or -5 is odd
def even_or_odd(n): if n == 0: # If number is zero, return zero return "Zero" elif n % 2 == 0: # If remainder of division by 2 is 0, number is even return "Even" else: # Else the number is odd return "Odd"- def even_or_odd(n):
return 'Even' if n % 2 == 0 else 'Odd'- if n == 0: # If number is zero, return zero
- return "Zero"
- elif n % 2 == 0: # If remainder of division by 2 is 0, number is even
- return "Even"
- else: # Else the number is odd
- return "Odd"
