You're closing the while loop when the input is "" (nothing), but you try and cast the input to int before checking that there is anything in the string. score = input() while score != "": score = int(score) # do_stuff score = input()

I think you might have done this. Still, you can see the following code:- s=int(input()) print(s)

You get invalid literal error, when the input isn't an integer. In your while loop, you are comparing student_score with a string and it isn't a string...

Adeniran not sure but I think this may be due sololearn input problem as your program needs more than 1 input and it requires all input to be given in starting at time of running, if you are not giving proper input then it will cause error..
