In this article, you will learn how to remove spaces from string in Python.

Remove Spaces from String

In Python, you can remove spaces from a string using several methods. Here are some of them:

Using replace() method

The replace() method is used to replace a substring with another substring. You can use it to replace spaces with an empty string to remove spaces from the string.

string_with_spaces = "Hello World! How are you?"
string_without_spaces = string_with_spaces.replace(" ", "")
print(string_without_spaces)

# Output: HelloWorld!Howareyou?

Using join() method

The join() method is used to concatenate a list of strings into a single string. You can split the original string into a list of substrings using the split() method and then join them without spaces to remove spaces from the string.

string_with_spaces = "Hello World! How are you?"
string_list = string_with_spaces.split()
string_without_spaces = "".join(string_list)
print(string_without_spaces)

# Output: HelloWorld!Howareyou?

Using a loop

You can use a loop to iterate over each character in the string and append non-space characters to a new string.

string_with_spaces = "Hello World! How are you?"
string_without_spaces = ""
for char in string_with_spaces:
    if char != " ":
        string_without_spaces += char
print(string_without_spaces)

# Output: HelloWorld!Howareyou?

Using regular expressions

You can use the re module in Python to replace all whitespace characters (including spaces, tabs, and newlines) with an empty string.

import re

string_with_spaces = "Hello World! How are you?"
string_without_spaces = re.sub(r'\s+', '', string_with_spaces)
print(string_without_spaces)

# Output: HelloWorld!Howareyou?

Using list comprehension

You can remove spaces from a string in Python by using list comprehension.

string_with_spaces = "Hello World! How are you?"
string_without_spaces = ''.join([i for i in string_with_spaces if i != ' '])
print(string_without_spaces)

# Output: HelloWorld!Howareyou?

Using the filter() function and lambda expression

You can remove spaces from a string in Python using the filter() function and lambda expression.

string_with_spaces = "Hello World! How are you?"
string_without_spaces = ''.join(filter(lambda x: x != ' ', string_with_spaces))
print(string_without_spaces)

# Output: HelloWorld!Howareyou?

Using the translate() method and string.maketrans() function

You can remove spaces from a string in Python by using the translate() method and string.maketrans() function.

import string

string_with_spaces = "Hello World! How are you?"
table = string.maketrans("", "", " ")
string_without_spaces = string_with_spaces.translate(table)
print(string_without_spaces)

# Output: HelloWorld!Howareyou?
