How to Remove Spaces From a String in Python?

When working with words and sentences in Python, managing extra spaces in your text can be a common task that significantly impacts how you handle data. In this guide, we'll go through various methods for removing those spaces from text using Python. We'll cover real-life situations and explain each method in simple terms.

Why Removing Spaces Matters:

Spaces within strings can delay tasks such as data analysis, input validation, and text formatting. Whether we are handling user inputs, cleaning up data, or preparing text for display, knowing how to remove spaces systematically is the basic need of any developer. To make this task easy, we have implemented the following methods:

Method 1: Using str.replace() for Basic Removal:

The str. replace() method is straightforward to remove spaces from a string. It replaces a specified substring with another substring, effectively removing all instances of spaces:

Python code

original_string = "Hello there, Python is amazing!"
no_spaces = original_string.replace(" ", "")
print(no_spaces)  # Output: "Hellothere,Pythonisamazing!"

This method uses str.replace() to replace spaces with an empty string, effectively removing them.

Method 2: Splitting and Joining with str.split() and str.join():

This method involves splitting the string into a list of words and then joining them back together without spaces:

Python code

original_string = "Python is fun and versatile"
no_spaces = "".join(original_string.split())
print(no_spaces)  # Output: "Pythonisfunandversatile"

It splits the string into words using spaces as separators and joins them back together without spaces.

Method 3: Using List Comprehension for Custom Removal:

With list comprehension, you can iterate through characters in the string and construct a new string without spaces:

Python code

original_string = "Coding is so much fun!"
no_spaces = "".join([char for char in original_string if char != " "])
print(no_spaces)  # Output: "Codingissomuchfun!"

This method iterates through characters in the string, creating a new string without spaces using list comprehension.

Method 4: Utilizing str.translate() for Versatile Removal:

For a more versatile approach, str. translate() combined with a translation table can help remove spaces and other whitespace characters:

Python code

import string
original_string = "Spa ces, spa ces, everywhere!"
translator = str.maketrans("", "", string.whitespace)
no_spaces = original_string.translate(translator)
print(no_spaces)  # Output: "Spaces,spaces,everywhere!"

It employs str.translate() and a table to remove spaces and other whitespace characters.

Method 5: Advanced Removal with Regular Expressions (Regex):

Regular expressions provide a robust solution for handling complex whitespace scenarios:

Python code

import re
original_string = "Regex can be tricky at times"
no_spaces = re.sub(r"\s+", "", original_string)
print(no_spaces)  # Output: "Regexcanbetrickyatimes"

Regular expressions are used for complex whitespace removal, offering a robust solution.

Real-World Use Cases:

User Input Cleanup: Removing spaces from user inputs ensures consistent and valid data entry.

Text Analysis: Cleaned-up text is crucial for accurate text analysis and processing.

URL Generation: Removing spaces from text aids in generating clean and functional URLs.

Data Transformation: For transforming data, spaces might need to be eliminated.

Output Formatting: Cleaned text enhances the readability of the generated output.


Handling spaces within strings is a foundational skill in Python programming. With these methods at your disposal, you're equipped to tackle a range of scenarios where removing spaces is necessary. From basic replacements to advanced regular expressions, the techniques covered here empower you to work with text more effectively, resulting in cleaner and more reliable code.
