Integer Python Program

Question

I want to write a program which does: If the input number is positive, just print it out; If the input number is negative, print the abs number; if not a number, print "Error"

I don't know how to do the last step.

What do you have so far? Have you tried the "try:" method that shows up on Google? — Mateen Ulhaq, Nov 12 '19 at 01:58

This should work as you said:

num = input( 'need a number:' )
try :
    num = int(num)
    print( abs(num) )
except ValueError :
    print( 'not a number' )

You need to move `print( abs(num) )` into the `try` block, otherwise you'll get a second error trying to call `abs` on a string. – kaya3 Nov 12 '19 at 02:30
