This will work if you actually enter two numbers. But it will error if you enter a non-integer like letters etc.

Answer 2

Usually I write a try except block to handle user input, make assertions or provide default values.
You can also use something like this:

from random import randint
number = int(input() or randint(1, 10))
print(number)

A short explanation for what? Please describe precisely what you want to know.

For example:
#i need 2 inputs
X=int(input())
Y=int(input())
If X=#invalid input:
#then X=random.choice(from my list)
#and Y=no inputs:
And same to (X)
#i want a program like this

What is valid input? An integer number? A positive number? A number in a certain range?

I do something like this in most of my sololearn python codes, try/except looking for ValueError and AssertionError.
