Question

DIRECTIONS: Complete the following Programming Exercise in Python. Name the file Lastname_Firstname_E1.

You just started your summer internship with ImmunityPlus based in La Crosse, Wisconsin. You are working with the forecasting team to estimate how many doses of an immunization drug will be needed. For each drug estimation, you will be provided the following information:

corona.txt
39
20
31
10
42
49
54
21
70

- The size of the target population.
- The life expectancy, in years, of an individual in the population.
- A file containing ages, in years, of a sample of 12 people infected in the population.

To calculate the number of doses needed, proceed as follows:

- Calculate the average age of infection from the sample of 12 ages.
- Calculate the Base Reproduction Number (R0): ?0 = ???? ?????????? ??????? / ??? ?? ?????????
- Calculate the Herd Immunity Threshold (Q) ? = 1 − (1 / ?0)
- Calculate the estimated number of doses ????? = ? ∗ ?????????? ????

QUESTION: Construct a program that allows a user to enter the size of the target population, the life expectancy of an individual in the population, and the name of the sample file. Once this information is obtained, perform the above four calculations and output the result of each calculation, appropriately labeled.

Example: Enter population size: 329450000
Enter life expectancy: 78.87
Enter sample file name: corona.txt

Average Age of Infection: 40.25
Base Reproduction Number: 1.959503106
Herd Immunity Threshold: 0.48966654
Doses Required: 161320641.6

Answer 1

• Complete program is well commented for better understanding.
• Program follows all the instructions given in question.
• Snippets of program and corona.txt file are provided below the typed code.
• Output snippet is also attached below.

Program:

# Obtaining required input information
population_size = int(input("Enter population size: "))
life_expectancy = float(input("Enter life expectancy: "))
file_name = input("Enter sample file name: ")
# opening file with given filename
f = open(file_name)
# extracting file contents in int type by splitting file data and mapping into int
values_list = list(map(int, f.read().split('\n')))

# calculating average age of infection
average_age = sum(values_list)/len(values_list)
# Base reproduction number
R0 = life_expectancy/average_age
# herd immunity threshold
Q = 1 - (1/R0)
# estimate number of doses
e_num_doses = Q * population_size

# printing each calculation result using labels given in sample output
print("Average Age of Infection: ", average_age)
# rounding values accordingly to match with given sample output while printing
# these value rounding can be adjusted easily according to need
print("Base Reproduction Number: ", round(R0, 9))
print("Herd Immunity Threshold: ", round(Q, 8))
print("Doses Required: ", round(e_num_doses, 1))
