[GRASS-dev] how to represent an argument as a variable in a grass python command

[Michael Barton]

I'm trying to do a script that calls g.copy

I want the user to be able to select which type of data to copy. So instead of specifying:

grass.run_command('g.copy', rast='%s,%s' % (input, output))

I'd like to something equivalent to:

grass.run_command('g.copy', '%s=%s,%s' % (datatype, input, output))

where datatype is the form of grass data to copy (eg, rast, vect, etc)

The way I'd like to do this doesn't work. So what is the correct syntax here?

Thanks
Michael
