Please don't use 'DOS box' for Windows Command Prompt or other Windows 
consoles for running Windows programs from a command line.  DOSBox is 
program for running (old) DOS programs written for the IBM PC.  One use 
is running old games, such as some distributed by GOG.  Note that 
interactive command line interpreters existed long before MS/PC DOS.

For reasons explained especially well by Eryk Sun, you should probably 
use one python program as a master program to run others in succession.
