This is nice and simple and has the invertible property that Patrick
mentioned above. Thanks much!

Wow, that makes this much clearer! I wonder if this behaviour
shouldn't be mentioned in some form in the python docs?

I'm trying to use re to split a string into (any number of) pieces of
these kinds:
1) contiguous runs of letters
2) contiguous runs of digits
3) single other characters
e.g. 555tHe-rain.in#=1234 should give: [555, 'tHe', '-', 'rain',
'.',

I'm trying to use re to split a string into (any number of) pieces of
these kinds:
1) contiguous runs of letters
2) contiguous runs of digits
3) single other characters
e.g. 555tHe-rain.in#=1234 should give: [555, 'tHe', '-', 'rain',
'.',
[ python3.1.1, re.__version__='2.2.1' ]
I'm trying to use re to split a string into (any number of) pieces of
these kinds:
