Question

Write some code that counts the number of times the value associated with student_id appears in the list associated with incompletes and assigns this value to number_of_incompletes. You may use, if you wish, an additional variable, k.

Answer 1

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.
