Sometimes I want to split a string into lines, preserving the
end-of-line markers. In Perl this is really easy to do, by splitting
on the beginning-of-line anchor:
@lines = split /^/, $string;
But I can't figure out how to do the same thing with Python. E.g.:
import re
re.split('^', 'spam\nham\neggs\n')
['spam\nham\neggs\n']
re.split('(?m)^', 'spam\nham\neggs\n')
['spam\nham\neggs\n']
bol_re = re.compile('^', re.M)
bol_re.split('spam\nham\neggs\n')
['spam\nham\neggs\n']
Am I doing something wrong?

As you probably noticed from the other responses: No, you can't split
on _and_ keep the splitby text.
Looks like you'll have to roll your own.
def splitat(text, sep):
result = [line + sep for line in text.split(sep)]
if result[-1] == sep: # either remove extra element
result.pop()
else: # or extra sep from last element
result[-1] = result[-1][:-len(sep)]
return result
