Chapter 10, Problem 4P
The Social Security Administration maintains an actuarial life table that contains the probability that a person in the United States will die (http://www.ssa.gov/OACT/STATS/table4c6.html). The death probabilities from this table for 2009 are stored in the file LifeDeathProbability.txt that is included with the book’s source code. There are three values for each row the age, death probability for a male, and death probability for a female. For example, the first five lines are:
0 0.006990 0.005728
1 0.000447 0.000373
2 0.000301 0.000241
3 0.000233 0.000186
4 0.000177 0.000150
This says that a 3-year-old female has a 0 000186 chance of dying that year
Write a program that simulates how long you will live. The basic idea is to generate random numbers for each age until you “die”. For example, if you are a 1-year-old male, then if a random number is <−0.000447 then the simulation will say you live to age 1. Otherwise if the random number is > 0.000447 then go to the age 2 and generate another random number. If it is < 0.000301 then the simulation will say you will live to age 2, etc. The program should input your sex and age to determine which probabilities to use. The program should then simulate to what age you will live by starting with the death probability for the age and sex entered in the file. If the simulation reaches age 120 then stop and predict that the user will live to 120. This program is merely a simulation and will give different results each time it is run.

File names: color_square.py, chessboard.py, test_squares.py
Positions on a chess board are identified by a letter and a number. The letter identifies the column; the number identifies the row. See the image below.
You will provide the functions that allow us to determine:
if a chessboard square is either black or white, given its coordinates.
If the row/column is valid or not for the standard chessboard
For example, if we pass in “d” for the column and 4 for the row, your function that determines color should return the string: “BLACK”. If we pass in "k" for the column to your function that validates columns, that function should return the boolean False.
Requirements:
Your function for validating the column should be able to accept upper or lowercase strings as parameters.
Your functions for validating the row should be able to accept integers or strings as parameters.
Your function that determines black-or-white may assume that the input has been validated prior to us calling…

Binus’s Used Cars, Inc. employs several salespeople. Mr. Robert, the owner of the company, has provided a file that contains sales records for each salesperson for the past month. Each record in the file contains the following two fields:
The salesperson’s ID number, as an integer
The amount of a sale, as a real number
The records are already sorted by salesperson ID. Brewster wants you to design a program that prints a sales report. The report should show each salesperson’s sales and the total sales for that salesperson. The report should also show the total sales for all salespeople for the month. Here is an example of how the sales report should appear:

World Series Champions If you have downloaded this book’s source code (the companion Web site is available at www.pearsonhighered.com/gaddis), you will find a file named WorldSeriesWinners.txt. This file contains a chronological list of the winning teams in the World Series from 1903 through 2009. (The first line in the file is the name of the team that won in 1903, and the last line is the name of the team that won in 2009. Note that the World Series was not played in 1904 or 1994, so those years are skipped in the file.)

One common physical activity that most of these devices track is the number of steps you take each day. The steps.txt file contains the number of steps a person has taken each day for a year. There are 365 lines in the file, and each line contains the number of steps taken during a day.

Open and process that file, reporting the number of words in the file and the number of words containing each letter, and the length of that word. Assume that any word exceeding nine characters is counted as a ten character word. If the same letter appears more than once, it is counted only once. The result should be a matrix of 26 rows (one row for each letter) and ten columns (one column for each word length (1-10), and the contents of the matrix must be displayed. As an example, assume the file contains only two words - “rotten” and “egg”. When processing “rotten”, rows for r, o, t, e and n would have the contents of column 6 incremented because “rotten” is a six letter word. When processing “egg”, rows for e and g would have the contents of column 3 incremented because “egg” is a three letter word.arrow_forward
