In Python, how do I split a string and keep the separators?

python regex

>>> re.split('(\W)', 'foo/bar spam\neggs')['foo', '/', 'bar', ' ', 'spam', '\n', 'eggs']

python regex

If you are splitting on newline, use splitlines(True).

>>> 'line 1\nline 2\nline without newline'.splitlines(True)['line 1\n', 'line 2\n', 'line without newline']

(Not a general solution, but adding this here in case someone comes here not realizing this method existed.)

python regex

another example, split on non alpha-numeric and keep the separators

import rea = "foo,bar@candy*ice%cream"re.split('([^a-zA-Z0-9])',a)

output:

['foo', ',', 'bar', '@', 'candy', '*', 'ice', '%', 'cream']

explanation

re.split('([^a-zA-Z0-9])',a)() <- keep the separators[] <- match everything in between^a-zA-Z0-9 <-except alphabets, upper/lower and numbers.
