When running this code in phyton, I received the following error. Can you help me, please? code:
num1 = int(input())

num2 = int(input())

if num2 < num1:

print("Second integer can't be less than the first.")

else:

for i in range(num1,num2+1,5):

print(i, end=" ")

error:

Traceback (most recent call last):
File "main. py", line 1, in
num1 = int(input())
ValueError: invalid literal for int() with base 10: '-15 30'
