How to call a script from another?

[Christian]

From a not even newbie:

Without knowing much about Python (yet) I'm trying to install the CMS
Zope via FTP (with the well documented changes to make it work on an
Apache server).
By birth Zope is started from a shell script. And not having the
permissions to execute such ones I'll try writing a .py script (with the
shebang that I allready knows will do the job) to call another .py
script like the original shell script does.

So my question is:
How do I call a .py script from another .py script?
(Writing the rest - I hope - is piece of cake ;-) ).

(And yes, I know that there are a lot of other problems but for starters
I just would like to try to call a .py script from another .py script.)


Thanks

Chris

Re: How to call a script from another?

I think this is the simplest way to do that:

import sys
sys.path.append ('/path/to/directory/containg/script')

import zopescript
zopescript.main ()

The code above assumes:
o that the path you use to append contains an __init__.py in it...
o zopescript is the module you want to `run'
o main is the method in zopescript that cranks up zope.

I'm not sure of how to do it the hard way...

I don't think this is necessary. The __init__.py is necessary
if you do something like:
import sys
sys.path.append ('/path/to/directory/containing')
from script import zopescript
zopescript.main ()
# or import zopescript.scri pt; script.zopescri pt.main()
That is, if the directory ".../containing" needs to be interpreted as
a package.

If the script you want to call is in the same directory as the script
calling it (or any directory on the path), you can simply use:
import zopescript
zopescript.main ()

Pardon? If you can't execute "shell scripts", how do you intend to
execute the python script to execute the other python script?

Well... an overly simplified explanation... You create a command
shell and pass the name of the script to it (back to problem #1)

import os
os.system("pyth on myOtherPython.p y")

{If you have a new enough Python release, there is a subprocess module
that has a bit more capability}

OTOH, if the script is designed as an importable module, you could

import myOtherPython
myOtherPython.m OP_main_entry_p oint()
