List from string of digits question
<p>I'm getting a string from input() wich consists of digits separated by spaces (1 5 6 3). First i'm trying to check that the input only consists of digits with the isdigit() function but because of the spaces i cant get it to work. Then i convert the string to a list using the split() function.</p>

<p>What i need is to make a list from input and make shure it only consists of digits, else send a message and ask for a new input. Is it maby possible to add a parameter to isdigit() that makes an exeption for spaces?</p>

<p>Thank you</p>
