#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

Explanation:

In the given question some data is missing so, program description can be defined as follows:

In the given python code, the method "average_heart_rate" defined that accepts list "beats" as the parameter, inside the method two-variable "total and count_list " is defined that holds a value that is 0.In the next line, a for loop is that uses the list and if block is defined that checks list value is greater then 100. Inside the loop, it calculates the addition and its count value and stores its values in total and count_list  variable, and returns its average value.
