Question

You have more flexibility to implement your own function names and logic in these programs.
The data files you need for this assignment can obtained from:

Right-click and "Save Link As..."
- HUGO_genes.txt (Links to an external site.)
- chr21_genes.txt (Links to an external site.)
Create an output directory inside your assignment4 directory called "OUTPUT" for result files, so that they will not mix with your programs. Output from your programs will be here!
Your program must implement command line options for the infiles it must open, but for testing purposes it should run by default, so if no command line option is passed at the command line, the program will still run. This will help in the grading of your program.
Create a Python Module called called my_io.py - You can use the same code from assignment 3's solution. Put this my_io.py Module in a subdirectory named assignment4 inside your assignment4 top-level directory (see the tree below, and see Lecture 7 on how to implement a Python module and a package). Anytime a file needs to be opened (read or write) in your programs in this assignment, the program should call on this module's function get_fh. You can then use my_io.get_fh by doing this at the top of your programs:

from assignment4 import my_io

# I can then use the module's get_fh() function by:
fh_in = my_io.get_fh(infile1, "r") # note the function call "myio.get_fh()"

from assignment4.my_io import get_fh

# I can then use the module's get_fh() function by:
fh_in = get_fh(infile1, "r") # note the function call "get_fh()"
