#A student took four courses in Fall 2017 semester. Write a program that 
#asks user to enter final grade for each course in Fall 2017 and finds the 
#average grade for Fall 2017 semester. 

#Discussion
#Input: 4 inputs, we will assume that grades are integers, stored in variables
#grade1, grade2, grade3, grade4
#Output: average, integer
#Calculations: average(grade1+grade2+grade3+grade4)//4 - pay attention, we need to 
#use integer division to get an integer result for average.

#Input
grade1=int(input("enter grade 1 "))
grade2=int(input("enter grade 2 "))
grade3=int(input("enter grade 3 "))
grade4=int(input("enter grade 4 "))

#Calculations
average=(grade1+grade2+grade3+grade4)//4

#Output
print("The average grade is", average)

#Test:
#grade1=67 grade2=90 grade3=78 grade4=100 then average is 83
