How do I get python to recognize that there has been no input

Question

I would like to create a program in which if the user presses the enter key without typing in anything, python would recognize the lack of input and relocate it to the appropriate actions. For example:

some = int(input("Enter a number"))

if not some:
    print("You didn't enter a number")

else:
    print("Good job")

What I would like to happen is if the user pressed the enter key without typing a value, they would receive the first statement. However, currently I only receive an error. Thank you.

Edit: I've had various responses about putting a try catch statement. Actually, in my original code I had a error handling statement for a ValueError. However I would like to distinguish between the user entering words instead of numbers and the user not entering anything. Is this possible?

Answer 1

I think this is what you're looking for

try:
    some = int(input("Enter a number"))
    print("Good job")
except (SyntaxError, ValueError):
    print("You didn't enter a number")
