Error or Bug??

1. Write a program to get two integer inputs, assign them to variables, perform Addition, Multiplication, and Division on the two inputs, and print the results on each line.

   Input:

   Two integers num1 and num2 (-10^9 ≤ num1, num2 ≤ 10^9).

   Output:

   Print the results of Addition, Multiplication, and Division on each line.

   Sample Input:

   10
   20

   Sample Output:

   30
   200
   0.5

My Code:

a= int(input())

b= int(input())

print(a+b)

print(a-b)

print(a/b)

PROBLEM: in other Compilers it was running successfully . but here , it not! why?

Output:

>>> Traceback (most recent call last):
  File "script-3.6.0.py", line 1, in 
    a= int(input())
EOFError: EOF when reading a line
