Start (multiple) parallel processes

6
Hi there,

How can i use os.popen or os.startfile to start a parallel running python script from within my running script?
i don't get the usage of these two -.-
with popen it seems as if the parent programm pauses and only the child programm is running, but i need both to run -.-

  1. run="python "+file_to_run
  2. os.popen(run)

Look at the thread module.

More details on the thread module can be found
here

Of course, the docs are also worth looking at.

As i understand it that's not exactly what I need...
Threats are parallel processes within a single file, aren't they?

What I want is the following:
I have the Files 'File1.py', 'File2.py', 'FileXY.py' ...
I start File1.py, and this File1 then starts File2.py, but it should go on to run (and not to wait for File2.py to finish). File2.py again starts File3.py and so on...
I don't need any result from these Files, I just need to start them.

Thx

Yeah. That's what threads are for! Start a thread and do the popen stuff. Then carry on with the rest of the file.
