why didn't you say this in the first place?
def coord2tuple(coord):
row, col = '', ''
alpha = 'abcdefghijklmnopqrstuvwxyz'.upper()
pairs = [''.join((x,y)) for x in alpha for y in [''] + [z for z in alpha]]
pairs = sorted(pairs, key=len)
coord = coord.upper()
for c in coord:
if c in alpha:
row += c
else:
col += c
return (int(col)-1, pairs.index(row))
>>> coord2tuple('B14')
(13, 1)
>>> coord2tuple('ZZ14')
(13, 701)
>>> coord2tuple('ZZ175')
(174, 701)
>>> coord2tuple('A2')
(1, 0)
Are there cols greater than ZZ? I seem to remember that there are not,
but I could be wrong.
Hope this helps.
Peace
