How do I convert the str to int without an error

def grading(): if student_score <40: print("Grade: F") elif student_score <46: print("Grade: E") elif student_score <50: print("Grade: D") elif student_score <60: print("Grade: C") elif student_score <70: print("Grade: B") elif student_score >70: print("Grade: A") student_score=int(input("Enter the student score or enter to exist")) total_score=0 number_of_students=0 grading() while student_score != "": total_score+= student_score number_of_students+=1 student_score=int(input("Enter the student_score or enter to exist")) grading () print("number of students =",number_of_students) average= total_score / number_of_students print("Average=",average)

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..

Use type casting property Example:- Store="58" restore=int(store) print(restore)
