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

Expert Solution

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)
