Solution Exercise 78: Python algorithm that returns the firts index of the average that is less than 10

Exercise 78

Given a list made up of the students' averages avg_list, write a python algorithm that determines the first index of the average which is less than 10. Example if

avg_list = [12, 17, 10, 7, 11, 14, 15, 9]

, the algorithm returns index 3.

Solution

def avgInf10 (L):
     # initialization of the index of average which is less than 10
     avg_index = 0
     for i in range (0, len (L)):
          if L[i] < 10:
               avg_index = i
               break
     return avg_index
 
# Example
avg_list = [12, 17, 10, 7, 11, 14, 15, 9]
print (avgInf10 (avg_list))
#The output of the program is: 3
