Arithmetic Operators | HackerRank

Goal

1. Read two integers from STDIN.

2. Solve tasks to use arithmetic operators. 

Solution

You can read values by using input() function. The important thing is to convert input() value into integer type because Input() function returns string value from input. 

After read two integer values, you can calculate vaules for each task.

# Arithmetic Operators

if __name__ == '__main__':
    a = int(input())
    b = int(input())
    
    sum = a + b
    difference = a - b
    product = a * b
    
    print(sum)
    print(difference)
    print(product)

Python If-Else | HackerRank

Goal

You need to print "Weird" if the number is weird in under condition. Otherweise, print "Not Weird". 

Solution

You can follow what conditions say, then it would be easy.

# Python If-Else

import math
import os
import random
import re
import sys


if __name__ == '__main__':
    n = int(input().strip())
    
    if (n % 2) !=0 : 
        print('Weird')
    else:
        if (n >=2 and n <=5):
            print('Not Weird')
        
        elif (n >=6 and n <=20):
            print('Weird')
            
        else:
            print('Not Weird')
