Run a python script with arguments

Question

I want to call a Python script from C, passing some arguments that are needed in the script.

The script I want to use is mrsync, or multicast remote sync. I got this

Answer 1

You have two options.

1. Call

   system("python mrsync.py -m /tmp/targets.list -s /tmp/sourcedata -t /tmp/targetdata")
   

   in your C code.

2. Actually use the API that mrsync (hopefully) defines. This is more flexible, but much more complicated. The first step would be to work out how you would perform the above operation as a Python function call. If mrsync has been written nicely, there will be a function mrsync.sync (say) that you call as

   mrsync.sync("/tmp/targets.list", "/tmp/sourcedata", "/tmp/targetdata")
   

   Once you've worked out how to do that, you can call the function directly from the C code using the Python API.
