string split in python

Question

I want to split string between a tab. Let's say I have some text in a file.txt

Kern_County_Museum  1,000,000+
Fairplex_railway_exhibit    Depot and rolling stock

So I want to remove redundancy from left side and keep right side as it is.

import re
import string
import urllib

for line in open('file.txt', 'r').readlines():
left, right = string.split(line, maxsplit=1)
relation = string.split(line, maxsplit=1)

le = relation[0]
ri = relation[1]

le = urllib.unquote(relation[0])
le = le.replace('_', ' ')


print le, '\t', ri

You should not use string.split(). Each string object provide the split() method directly. — user2665694

Restrain your split.

left, right = line.split(None, 1)

By default split method splits string by any whitespace. To split string by a tab, pass extra parameter to this method:

left, right = line.split('\t', 1)

I thought they split by whitespace, rather than " "

@samb8s well, yes, by any white-space.

@Blue it looks like you are still using your original version of split.

@Blue Ice, if you're using Python older than 2.5, it's a good idea to mention it in the question/tags
