How to Remove Spaces from String in Python Easily

To remove all spaces from a string in Python, use str.replace(' ', ''). To remove spaces only at the start and end, use str.strip().

Syntax

Here are common ways to remove spaces from strings in Python:

• str.replace(' ', ''): Removes all spaces inside the string.
• str.strip(): Removes spaces only at the start and end of the string.
• str.lstrip(): Removes spaces only at the start (left side).
• str.rstrip(): Removes spaces only at the end (right side).

python

string.replace(' ', '')
string.strip()
string.lstrip()
string.rstrip()

Example

This example shows how to remove all spaces and how to remove only leading and trailing spaces.

python

text = '  Hello World  '

# Remove all spaces
no_spaces = text.replace(' ', '')

# Remove spaces only at start and end
trimmed = text.strip()

print('Original:', repr(text))
print('No spaces:', repr(no_spaces))
print('Trimmed:', repr(trimmed))

Output

Original: '  Hello World  '
No spaces: 'HelloWorld'
Trimmed: 'Hello World'

Common Pitfalls

One common mistake is using strip() when you want to remove all spaces inside the string. strip() only removes spaces at the start and end, not in the middle.

Another mistake is forgetting that replace() is case-sensitive and only replaces exact matches.

python

text = '  Hello World  '

# Wrong: strip() does not remove spaces inside
wrong = text.strip()

# Right: replace() removes all spaces
right = text.replace(' ', '')

print('Wrong:', repr(wrong))
print('Right:', repr(right))

Output

Wrong: 'Hello World'
Right: 'HelloWorld'

Quick Reference

Use this quick guide to choose the right method:

Method	What it does	Example
str.replace(' ', '')	Removes all spaces anywhere in the string	'Hello World' → 'HelloWorld'
str.strip()	Removes spaces only at start and end	' Hello ' → 'Hello'
str.lstrip()	Removes spaces only at the start	' Hello ' → 'Hello '
str.rstrip()	Removes spaces only at the end	' Hello ' → ' Hello'

Key Takeaways

Use str.replace(' ', '') to remove all spaces inside a string.

Use str.strip() to remove spaces only at the start and end.

strip() does not remove spaces inside the string.

Remember lstrip() and rstrip() remove spaces only on one side.

Always check which spaces you want to remove before choosing a method.
