Thanks Paul,
I never used string module.
In fact, cellnames.split('') gives a syntax error w/ empty string.
That's why I use the intermediate replace() which accept that.

Hello,
I need a generator to create the cellname in a excell (using pyuno)
document to assign value to
the correct cell. The following code does this but do you have some
optimizations
on it, for instance to get the alphabetic chars instead of
hard-coding it.
you can use:
import string
cellnames = string.ascii_uppercase
not sure why you need the .replace().split() stuff...
def _xrange_cellnames(rows, cols):
cellnames = string.ascii_uppercase
for row in xrange(1, rows+1):
for char in cellnames[:rows]:
yield char + str(row)
cheers
