Explanation:
incompletes = [1,2,1,5,3,4,5,6,5,1,7]
student_id = 5
number_of_incompletes = 0
for k in incompletes:
if(k == student_id):
number_of_incompletes += 1
print("No. of incompletes = ",number_of_incompletes)
In this program, "incompletes" is a variable where set of values are associated. "student_id" holds the value to be searched in the list. So the counter "number_of_incompletes" is set to 0 and it will be incremented in the for loop if the student id matches. Finally the number of incomplete gets printed.
Here the student_id is "hard-coded". If you want you get the input from the user too.
