[GRASS-user] using mapcalc in a python script

[Ned Horning]

I am working on converting a shell script to python and ran into a 
problem I haven't been able to figure out using the r.mapcalc command. 
Can someone let me know how to write the following command using python. 
The command creates a GRASS MASK layer:

r.mapcalc "MASK=if(($cloudResampName < 0.01000),1,null())"

I'm trying to run the python script using GRASS 6.40RC6 (2010).

All the best,

Ned
