how to call a shell script from python code?
+6
A:
The subprocess module will help you out.
Here is a decent tutorial.
Blatantly trivial example:
>>> import subprocess
>>> subprocess.call(['./test.sh']) # Thanks @Jim Dennis for suggesting the []
0
>>>
Where test.sh is a simple shell script and 0 is its return value for this run.

Note: it's preferable to pass subprocess.call() a list rather than a string (see command to Hugo24 below for the example and reasons).

A:
There is some ways using os.popen() (deprecated) or whole subprocess module, but os.system(command) is one of the easiest.

A:
Use the subprocess module as mentioned above.
I use it like this:
subprocess.call(["notepad"])

Note: calling subprocess with a list is safer since it doesn't necessitate passing the (potentially unsanitized) string through a shell for parsing/interpretation. The first item in the list will be the executable and all other items will be passed as arguments.
