#Imagine you're writing some code for an exercise tracker. #The tracker measures heart rate, and should display the #average heart rate from an exercise session. # #However, the tracker doesn't automatically know when the #exercise session began. It assumes the session starts the #first time it sees a heart rate of 100 or more, and ends #the first time it sees one under 100. # #Write a function called average_heart_rate. #average_heart_rate should have one parameter, a list of #integers. These integers represent heart rate measurements #taken 30 seconds apart. average_heart_rate should return #the average of all heart rates between the first 100+ #heart rate and the last one. Return this as an integer #(use floor division when calculating the average). # #You may assume that the list will only cross the 100 beats #per minute threshold once: once it goes above 100 and below #again, it will not go back above.

Following are the code to this question:

def average_heart_rate(beats):#defining a method average_heart_rate that accepts list beats  

   total=0 #defining integer variable total,that adds list values  

   count_list=0#defining a count_list integer variable, that counts list numbers  

   for i in beats:#defining for loop to add list values  

       if i>= 100:#defining if block to check value is greater then 100

           total += i#add list values

           count_list += 1# count list number  

   return total//count_list #return average_heart_rate value  

beats=[72,77,79,95,102,105,112,115,120,121,121,125, 125, 123, 119, 115, 105, 101, 96, 92, 90, 85]#defining a list

print("The average heart rate value:",average_heart_rate(beats)) # call the mnethod by passing value

Output:

The average heart rate value: 114
