8.2.2. Task 2
Task Instructions
Part A:
Please answer the following questions:
How would you open a file name test.txt to read only? To write only? To read and
write?
What is the general command structure for writing to a file?
How do you output a string to a file? An integer? A real number with three decimal
points?
Save your answers in a PDF named:
py4_team_teamnumber.pdf
Part B:
Your task is to write a program that prompts the user to input their last name, first
name, an integer representing their age in years, and an integer representing the
number of days elapsed since their most recent birthday. Each of these inputs will be
followed by a return (i.e., should be done in separate lines).
Given this data, your program should calculate the user’s total present age in years
then use a user-defined function to calculate and return the user’s age in whole
seconds.
Your program should then output the user’s name (first then last name), a real number
representing their total present age in years, and the number of whole seconds that
have elapsed in this time to a file named
py4_team_2_teamnumber.txt. Assume that
there are 365.242199 days in a year.
Before creating the program, create a flowchart of the algorithm you will use for this program. Save your flowchart as a separate page in the previously created PDF file. Then, write a Python program that implements your algorithm. Name your main program: py4_team_2_teamnumber.py
Sample Output
Use the values in Table 8.3
below to test your program.
Ensure your program’s output matches the provided samples exactly.
This includes all characters, white space, and punctuation. In the
samples, user input is highlighted like
this for clarity, but your program should not highlight user
input in this way.
Case 1 Sample Output
$ python3 py4_team_2_teamnumber.py
Enter your last name:
Purdue
Enter your first name:
John
Enter your age in whole years:
218
Enter the days elapsed since your last birthday:
332
