Python 3- Assign grade

Question

I am trying to write a program that reads a list of scores and then assigns a letter grade based on the score. Define a function to prompt user to enter valid scores until they

Answer 1

In this piece of code, you're not adding the value entered by the user to the list grade; you're re-defining grade so it's no longer a list but instead an integer:

def getScore():
   grade = []
   while grade != -999:
      grade = int(input("Enter grades (-999 ends): "))
   return grade

This wouldn't fly in strict, type-safe languages but, hey, it's python :)

To fix it, rename the list (grades would be an intuitive name) and use append() to add the value of grade to it. Then, return grades, not grade to get a list back.
