The code that read two numbers from user input, then, print the sum of those numbers are as follows:
x = int(input("write a number: "))
y = int(input("write another number: "))
print(x + y)

- The second line of code ask the user for another number input . The integer input is stored in a variable y.
- Finally, we print the sum of the user's input.
