[GRASS-dev] another grass python library question

Here is another issue with an infurating problem of parameter pairs.

I have input map names saved to a set of variables.
I want to do the following:

grass.run_command('g.copy ', raster=[variable],[mapname])

The output [mapname] can be a string for a mapname or a previously defined variable containing the mapname.

I’ve looked at the docs for the scripting and python libraries and nothing there helps. I consistently get a file not found error or a syntax error if I try to use string substitution.

What about:

grass.run_command(‘g.copy ‘, raster=’{},{}’.format(variable, ‘mapname’)

Could try. I found another way, after trying several that didn't work.
