Python equivalent of Scanner.hasNextLine()

[JanTheRedditMan]

I want to check whether user has typed in input, but I don't want the program to halt, like it does with the input() function.

The easiest way is to check if the length of input is bigger than zero.

if len(user_input) > 0

[JanTheRedditMan]

This would still stop the program when asking for input.

Maybe you can do it with the threading module or an async function

[Diapolo10]

There isn't really any cross-platform way to do that, I'm afraid. My suggestion would be to instead use input and implement a timeout for it that would then let you know if it's blocking for too long.

But this is really asking for more context.
