splitting a string based on tab in the file

You can use regexp to do this:

import re
patt = re.compile("[^\t]+")


s = "a\t\tbcde\t\tef"
patt.findall(s)
['a', 'bcde', 'ef']

You can use regex here:

>>> import re
>>> strs = "foo\tbar\t\tspam"
>>> re.split(r'\t+', strs)
['foo', 'bar', 'spam']

update:

You can use str.rstrip to get rid of trailing '\t' and then apply regex.

>>> yas = "yas\t\tbs\tcda\t\t"
>>> re.split(r'\t+', yas.rstrip('\t'))
['yas', 'bs', 'cda']

Split on tab, but then remove all blank matches.

text = "hi\tthere\t\t\tmy main man"
print [splits for splits in text.split("\t") if splits is not ""]

Outputs:

['hi', 'there', 'my main man']
