Here is one way:

bbox = (1,5,1,3)
ga('set parea %d %d %d %d'%bbox)

and another

x1 = 1
x2 = 5
y1 = 1
y2 = 3
ga('set parea %d %d %d %d'%(x1,x2,y1,y2))

You just pass a string to the ga() instance with the command you want to
execute. In these examples I am using tuples and standard string formating
operations in Python. Take your time to read the Python Tutorial,

      http://docs.python.org/tut/

You can use pygrads from the command line without knowing much about Python,
but
you will need to learn the language if you would like to program in it.

     Good Luck,

           Arlindo
