To strip empty spaces in a string in Python, use the following built-in functions:

Method

Description

Removes all trailing spaces (i.e. spaces on the right).

rstrip()

Removes all leading spaces (i.e. spaces on the left).

lstrip()

Removes all trailing and leading spaces.

strip()

Replace all " " (single space) characters with "".

replace()

Examples

Trailing spaces

To strip all trailing spaces:

x = " Hello World "
x.rstrip()
' Hello World'

Leading spaces

To strip all leading spaces:

y = " Hello World "
y.lstrip()
'Hello World '

Trailing and Leading spaces

To strip all trailing and leading spaces:

z = " Hello World "
z.strip()
'Hello World'

Note that in all these examples the original string is left intact and we return a new string with the spaces stripped.

All spaces

To replace all " " (single space) characters with "":

a = " Hello World "
a.replace(" ", "")
'HelloWorld'
NOTE

Using this method will only remove the normal ASCII space character and not other whitespace characters such as tabs.

Duplicated spaces

To remove duplicated space characters:

b = " Hello World "
" ".join(b.split())
'Hello World'

Here we first split the string " Hello World " into fragments using the space character as a separator. Then we rejoin these fragments using the join method using " " as the separator ensuring we only have single spaces.
