Question

You want to write a Python program to compute the average of three integer quiz grades for a single student. Decide what variables your program needs, and create them with appropriate initial values

Answer 1

Here is code in python.

#define three variables to store grades

grade_1 = 0

grade_2 = 0

grade_3 = 0

//define variable to store average of all three quiz

avg_grade=0

// read score of 1st quiz as integer

grade_1 = int (input ("please enter score of first quiz: "))

// read score of 2nd quiz as integer

grade_2 = int (input ("please enter score of second quiz: "))

// read score of 3rd quiz as integer

grade_3 = int (input ("please enter score of third quiz: "))

//calculate average of three grades

avg_grade = (grade_1 + grade_2 + grade_3)/3

// print the average

print ("Average of three quizs is {}".format(avg_grade))

Step-by-step explanation:

Declare three variables "grade_1","grade_2" and "grade_3" to store the score of 3 quiz. And variable "avg_grade" to store the average of all quiz.Read score of quiz as integer and then calculate their average and assign it "avg_grade".

Output:

please enter score of first quiz: 23

please enter score of second quiz: 33

please enter score of third quiz: 45

Average of three quiz is 33.6666
