As part of this assignment, the program that you will be writing will store current grades in a dictionary using course codes as keys and with values consisting of percent grades in lists. The main functions of this program are to print a student's gradebook, to drop the lowest grade in each course, print the student's gradebook again, drop the course with lowest average, and finally printing the student's gradebook again. This program requires a main function and a custom value-returning function. In the main function, code these basic steps in this sequence (intermediate steps may be missing): start with an empty dictionary that represents a gradebook and then use a while loop to allow the input of course codes from the keyboard. End the while loop when the user presses enter without entering data.within the while loop:for each course entered, use a list comprehension to generate five random integers in the range of 70 through 100. These random integers in a list represent the…
