The way to use urllib.encode is like this:

>>> urllib.urlencode({"key":"value"})
'key=value'
>>> urllib.urlencode({"key":"value","key2":"value2"})
'key2=value2&key=value'

For your purpses, you need to construct the dict this way:

>>> urllib.urlencode({"FHI":'128,128',"FHO":'1,1'})
'FHO=1%2C1&FHI=128%2C128'
>>> 


And if you are to use variables, one way to do it would be:

>>> x1,y1,x2,y2 = 1,1,128,128
>>> fhi = str(x2) + ',' + str(y2)
>>> fho = str(x1) + ',' + str(y1)
>>> urllib.urlencode({"FHI":fhi,"FHO":fho})
'FHO=1%2C1&FHI=128%2C128'
