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 /^/, $string;
But I can't figure out how to do the same thing with Python. E.g.:
import re
re.split('^', 'spam\nham\neggs\n')
['spam\nham\neggs\n']
re.split('(?m)^', 'spam\nham\neggs\n')
['spam\nham\neggs\n']
bol_re = re.compile('^', re.M)
bol_re.split('spam\nham\neggs\n')
['spam\nham\neggs\n']
Am I doing something wrong?
Just split on the EOL character: the "\n":
re.split('\n', 'spam\nham\neggs\n')
['spam', 'ham', 'eggs', '']
The "^" and "$" characters do not match END-OF-LINE, but rather the
END-OF-STRING, which was doing you no good.
With the MULTLINE flag "^" matches START-OF-LINE and "$" matches
END-OF-LINE or END-OF-STRING.
The current re module won't split on a zero-width match.
