What's the best way to do the inverse operation of the .join
function?
Use the str.split method?
split is perfect except for what happens with an empty string.
I see what you mean.
This is consistent:
>>> ','.join([''])
''
>>> ''.split(',')
['']
but this isn't:
>>> ','.join([])
''
>>> ''.split(',')
['']
An empty string could be the result of .join(['']) or .join([]).
Should .split grow an addition keyword argument to specify the desired
behaviour? (Although it's simple enough to define your own function.)
