How do I trim whitespace?
For whitespace on both sides use str.strip
:
s = " \t a string example\t "s = s.strip()
For whitespace on the right side use rstrip
:
s = s.rstrip()
For whitespace on the left side lstrip
:
s = s.lstrip()
As thedz points out, you can provide an argument to strip arbitrary characters to any of these functions like this:
s = s.strip(' \t\n\r')
This will strip any space, \t
, \n
, or \r
characters from the left-hand side, right-hand side, or both sides of the string.
The examples above only remove strings from the left-hand and right-hand sides of strings. If you want to also remove characters from the middle of a string, try re.sub
:
import reprint(re.sub('[\s+]', '', s))
That should print out:

Python trim
method is called strip
:
str.strip() #trimstr.lstrip() #ltrimstr.rstrip() #rtrim
For leading and trailing whitespace:
s = ' foo \t 'print s.strip() # prints "foo"
Otherwise, a regular expression works:
import repat = re.compile(r'\s+')s = ' \t foo \t bar \t 'print pat.sub('', s) # prints "foobar"
