I need to remove whitespaces after the word in the string. Can this be done in one line of code?
Example:
string = " xyz "
desired result : " xyz"

>>> " xyz ".rstrip[]
' xyz'
There is more about rstrip in the documentation.

You can use strip[] or split[] to control the spaces values as the following, and here is some test functions:
words = " test words "
# Remove end spaces
def remove_end_spaces[string]:
return "".join[string.rstrip[]]
# Remove first and end spaces
def remove_first_end_spaces[string]:
return "".join[string.rstrip[].lstrip[]]
# Remove all spaces
def remove_all_spaces[string]:
return "".join[string.split[]]
# Remove all extra spaces
def remove_all_extra_spaces[string]:
return " ".join[string.split[]]
# Show results
print[f'"{words}"']
print[f'"{remove_end_spaces[words]}"']
print[f'"{remove_first_end_spaces[words]}"']
print[f'"{remove_all_spaces[words]}"']
print[f'"{remove_all_extra_spaces[words]}"']
output:
" test words "
" test words"
"test words"
"testwords"
"test words"
i hope this helpful .

There are various ways to remove spaces from a string in Python. This tutorial is aimed to provide a short example of various functions we can use to remove whitespaces from a string.
Python Remove Spaces from String
Python String is immutable, so we can’t change its value. Any function that manipulates string value returns a new string, and we have to explicitly assign it to the string. Otherwise, the string value won’t change. Let’s say we have an example string defined as:
s = ' Hello World From Pankaj \t\n\r\tHi There '
This string has different types of whitespaces as well as newline characters. Let’s have a look at different functions to remove spaces.
strip[]
Python String strip[] function will remove leading and trailing whitespaces.
>>> s.strip[]
'Hello World From Pankaj \t\n\r\tHi There'
If you want to remove only leading or trailing spaces, use lstrip[] or rstrip[] function instead.
replace[]
We can use replace[] to remove all the whitespaces from the string. This function will remove whitespaces between words too.
>>> s.replace[" ", ""]
'HelloWorldFromPankaj\t\n\r\tHiThere'
join[] with split[]
If you want to get rid of all the duplicate whitespaces and newline characters, then you can use join[] function with string split[]
function.
>>> " ".join[s.split[]]
'Hello World From Pankaj Hi There'
translate[]
If you want to get rid of all the whitespaces as well as newline characters, you can use string translate[] function.
>>> import string
>>> s.translate[{ord[c]: None for c in string.whitespace}]
'HelloWorldFromPankajHiThere'
Python Remove Whitespaces from String using Regex
We can also use a regular expression to match
whitespace and remove them using re.sub[] function.
import re
s = ' Hello World From Pankaj \t\n\r\tHi There '
print['Remove all spaces using RegEx:\n', re.sub[r"\s+", "", s], sep=''] # \s matches all white spaces
print['Remove leading spaces using RegEx:\n', re.sub[r"^\s+", "", s], sep=''] # ^ matches start
print['Remove trailing spaces using RegEx:\n', re.sub[r"\s+$", "", s], sep=''] # $ matches end
print['Remove leading and trailing spaces using RegEx:\n', re.sub[r"^\s+|\s+$", "", s], sep=''] # | for OR condition
Output:
Remove all spaces using RegEx:
HelloWorldFromPankajHiThere
Remove leading spaces using RegEx:
Hello World From Pankaj
Hi There
Remove trailing spaces using RegEx:
Hello World From Pankaj
Hi There
Remove leading and trailing spaces using RegEx:
Hello World From Pankaj
Hi There
