Core Python Programming

9.8. File Execution

Whether we want to simply run an operating system command, invoke a binary executable, or another type of script (perhaps a shell script, Perl, or Tcl/Tk), this involves executing another file somewhere else on the system. Even running other Python code may call for starting up another Python interpreter, although that may not always be the case. In any regard, we will defer this subject to Chapter 14. Please proceed there if you are interested in how to start other programs, perhaps even communicating with them, and for general information regarding Python's execution environment.
