Question 4:
Textbook P.80, Q4:
The U.S. Cencus provides information on its web page (http://www.census.gov) about the current U.S. population as well as approximate rates of change. Three rates of change are provided:
-‐ There is a birth every 7 seconds.
-‐ There is a death every 13 seconds.
-‐ There is a new immigrant every 35 seconds.
These are obviously approximations of birth, death, and immigration rates, but they can assist in providing population estimates in the near term.
Write a program that takes years as input (as a integer) and prints out an estimated population (as an integer). Assume that the current population is 307,357,870, and assume that there are exactly 365 days in a year. Hint: Note that the rate units are in seconds.
Submission instructions:
You should submit your homework in the NYU Classes system.
For this assignment you should turn in 3 files:
A ‘.pdf‘ file with the base conversions (For questions 1 and 2). Make sure to include the conversion calculations, not just the final answer.
Two ‘.py’ files, one containing a script for question 3 and the other for question4. Name your files ‘q3.py’ and ‘q4.py’ respectively.
