Well, if you want to have some fun with list comprehensions . . . :
>>> v = "64x43x12"
>>> [i[::-1] for i in v[::-1].split("x",1)[::-1]]
['64x43', '12']
On the other hand, if you're not as list comprehension happy as I am,
you could write a function to do the same thing:
>>> def rsplit(string, sep=" ", maxsplit=-1):
string = string[::-1]
stringlist = string.split(sep, maxsplit)
stringlist = stringlist[::-1]
for i in range(len(stringlist)):
stringlist[i] = stringlist[i][::-1]
return stringlist
>>> rsplit(v, "x", 1)
['64x43', '12']
