How to Remove Spaces from String in Python

To remove spaces from a string in Python, use the str.replace() method.

This method takes two arguments:

• The first argument is the string to be replaced.
• The second argument is the string that replaces the string.

string = "This is a test" nospaces = string.replace(" ", "") print(nospaces)

In this guide, we take a look at other common situations related to removing spaces from a string.

Howt to Remove White Spaces in Python String

In Python, a string is an immutable type. This means it cannot be directly modified. This means any method that manipulates strings actually creates a new string.

In Python, there are many ways you can replace blank spaces:

Let’s go through each of these options and when you should use them.

1. str.strip()—Remove Leading and Trailing Spaces

The str.strip() method removes the leading and trailing whitespace from a string.

string = " This is a test " modified = string.strip() print(modified)

2. str.replace()—Remove All White Spaces

To wipe out all the white spaces from a string, you can use the str.replace() method.

This method takes two mandatory arguments:

1. The target strings you want to get rid of.
2. The string that replaces all the target strings.

In other words, to remove the white spaces, replace each white space with an empty string.

string = "This is a test" modified = string.replace(" ", "") print(modified)

3. str.join() and str.split()—Remove Duplicate White Spaces

To get rid of tabs, newlines, or any other duplicate whitespaces use str.join() method with str.split().

• The str.split() method splits the string into a list of words without spaces.
• The str.join() takes a list of words and joins them using the str as a separator.

For example, let’s remove the duplicate white spaces but leave single white spaces:

before = "This \t is a \n test \n\n \t let's modify this" after = " ".join(before.split()) print(before) print(after)

This is a test let's modify this This is a test let's modify this

4. str.translate()—Remove Tabs, Newlines, and Other White Spaces

To get rid of all the white spaces, tabs, newlines, you can use the str.translate() method with str.maketrans() method.

The str.translate() method replaces strings according to a translation table created by str.maketrans() method. In short, the str.maketrans() method works such that it takes three arguments:

1. A string to be replaced.
2. A string that specifies the characters to be replaced in the first argument.
3. A list of characters to be removed from the original string. To remove white spaces, use string.whitespaces, which is a list of the types of blank spaces.

import string before = "This \t is a \n test \n\n \t let's modify this" after = before.translate(str.maketrans("", "", string.whitespace)) print(before) print(after)

Thisisatestlet'smodifythis

5. re.sub()—Replace White Spaces with Empty Strings

RegEx or Regular Expression is like a Ctrl+F on steroids.

You can use it to match patterns in a string. You can for example use regex to find phone numbers or email addresses from a text document.

I am not going to go into more details about regex, but here is a great article you can check.

To use Regular Expressions in Python to remove white spaces from a string:

1. Import the regex module, re, to your project.
2. Define a regex pattern that matches white spaces.
3. Substitute each white space with a blank space using re.sub() method.

import re string = "This is a test" # Regular expression that matches each white space whitespace = r"\s+" # Replace all mathces with an empty string nospaces = re.sub(whitespace, "", string) print(nospaces)

Conclusion

Today you learned five ways to remove white spaces and duplicate white spaces from Python strings in different situations. Feel free to use the one that best fits your needs!

Thanks for reading. I hope you found an answer to your question.

How To Remove Spaces from a String In Python

This tutorial provides examples of various methods you can use to remove whitespace from a string in Python.

A Python String is immutable, so you can’t change its value. Any method that manipulates a string value returns a new string.

The examples in this tutorial use the Python interactive console in the command line to demonstrate different methods that remove spaces. The examples use the following string:

s = ' Hello World From DigitalOcean \t\n\r\tHi There ' 

Output
 Hello World From DigitalOcean Hi There 

This string has different types of whitespace and newline characters, such as space ( ), tab ( \t ), newline ( \n ), and carriage return ( \r ).

Remove Leading and Trailing Spaces Using the strip() Method

The Python String strip() method removes leading and trailing characters from a string. The default character to remove is space.

Declare the string variable:

Use the strip() method to remove the leading and trailing whitespace:

Output
'Hello World From DigitalOcean \t\n\r\tHi There' 

If you want to remove only the leading spaces or trailing spaces, then you can use the lstrip() and rstrip() methods.

Remove All Spaces Using the replace() Method

You can use the replace() method to remove all the whitespace characters from the string, including from between words.

Declare the string variable:

Use the replace() method to replace spaces with an empty string:

Output
'HelloWorldFromDigitalOcean\t\n\r\tHiThere' 

Remove Duplicate Spaces and Newline Characters Using the join() and split() Methods

You can remove all of the duplicate whitespace and newline characters by using the join() method with the split() method. In this example, the split() method breaks up the string into a list, using the default separator of any whitespace character. Then, the join() method joins the list back into one string with a single space ( » » ) between each word.

Declare the string variable:

Use the join() and split() methods together to remove duplicate spaces and newline characters:

Output
'Hello World From DigitalOcean Hi There' 

Remove All Spaces and Newline Characters Using the translate() Method

You can remove all of the whitespace and newline characters using the translate() method. The translate() method replaces specified characters with characters defined in a dictionary or mapping table. The following example uses a custom dictionary with the string.whitespace string constant, which contains all the whitespace characters. The custom dictionary replaces all the characters in string.whitespace with None .

Import the string module so that you can use string.whitespace :

Declare the string variable:

Use the translate() method to remove all whitespace characters:

Output
'HelloWorldFromDigitalOceanHiThere' 

Remove Whitespace Characters Using Regex

You can also use a regular expression to match whitespace characters and remove them using the re.sub() function.

This example uses the following file, regexspaces.py , to show some ways you can use regex to remove whitespace characters:

import re s = ' Hello World From DigitalOcean \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 

Run the file from the command line:

You get the following output:

Remove all spaces using regex: HelloWorldFromDigitalOceanHiThere Remove leading spaces using regex: Hello World From DigitalOcean Hi There Remove trailing spaces using regex: Hello World From DigitalOcean Hi There Remove leading and trailing spaces using regex: Hello World From DigitalOcean Hi There
