PyInstaller/Py2exe - include os.system call with third party scripts in single file compilation
Question: I'm using tkinter and pyinstaller/py2exe (either one would be fine), to create
an executable as a single file from my python script. I can create the
executable, and it runs as desired when not using the bundle option with
py2exe or -F option with pyinstaller. I'm running third party python scripts
within my code with os.system(), and can simply place these scripts in the
'dist' dir after it is created in order for it to work. The command has
several parameters: input file, output file, number of threads..etc, so I'm
unsure how to add this into my code using import. Unfortunately, this is on
Windows, so some colleagues can use the GUI, and would like to have the single
executable to distribute.

**EDIT:**I can get it to bundle into a single executable, and provide the
scripts along with the exe. The issue still however, is with
`os.system("python script.py -1 inputfile -n numbthreads -o outputfile..")`
when running the third party scripts within my code. I had a colleague test
the executable with the scripts provided with it, however at this point they
need to have python installed, which is unacceptable since there will be
multiple users.


Answer: After a couple of days of some tests, I was able to figure out how to work
around this problem. Instead of `os.system`, I am using
`subprocess.call("script.py arg1 arg2 ..., shell=True)` for each script I need
to run. Also, I used `chmod +x` (in linux) before transferring the scripts to
windows to ensure they're an executable (someone can hopefully tell me if this
was really necessary). Then without having to install python a colleague was
able to run the program, after I compiled it as a single file with
pyInstaller. I was also able to do the same thing with blast executables
(where the user did not have to install blast locally - if the exe also
accompanied the distribution of the script). This avoided having to call
bipython ncbiblastncommandline and the install.
