Python 3

Assume a Dictionary structure exists that associates letter grades (“A”, “B”, “C”, etc.) to their respective numeric range (expressed as a string, for example: “90,100”, “80,89”, “70,79”, etc.). The name of the structure is gradeConvert. Write a single Python statement to retrieve the point range for a letter grade of "B". Store the retrieved value in a variable named "ptRange".

Write a Python function that meets the following requirements:

Is named findRange
Accepts a single argument of type string
Uses the argument to retrieve the related point range value from the Dictionary named gradeConvert (DO NOT define the Dictionary here)
Returns the retrieved string (point range)
