Question

Use Python

Write a function with no parameters, even_or_odd()

Specifications:

 

  • read an integer from standard input
  • return 0 if the integer is even, 1 if the integer is odd
  • do not use a conditional ("if") statement, just use modular arithmetic (such as // or %)
  • do not print the result, return it

 

HINT: What is the remainder when you divide an even number by 2?  What is the remainder when you divide an odd number by 2?

REMINDER: DO NOT use prompts in your input statements for this problem.

 

For example:

Test Input Result
ans = even_or_odd() print(ans) 5 1
ans = even_or_odd() print(ans) -14 0
ans = even_or_odd() print(ans) 0 0
ans = even_or_odd() print(ans) 99

Step 1

Source code :-


def even_or_odd(num):
    # here we can made an array with value 0 , 1;
    arr = [0 , 1]
    # here i apply some logic which gives required result.
    return arr[num % 2]
    
    
num = int(input("Enter the number : "))
result = even_or_odd(num)
print(result)
