How to Remove Whitespace from a String in Python

If you need to clean up text in Python, there are a few common ways to remove whitespace from a string.

This page shows you how to:

Remove spaces at the beginning and end
Remove all normal spaces
Remove tabs and newline characters too
Choose the right method for the result you want

Quick fix

text = "  hello world  "
print(text.strip())           # hello world
print(text.replace(" ", ""))  # helloworld

Use strip() to remove whitespace at the start and end.

Use replace() to remove normal space characters everywhere.

What this page helps you do

Remove spaces at the beginning and end of a string
Remove all normal spaces from a string
Remove tabs and newline characters when needed
Choose the right method for your goal

Use `strip()` to remove whitespace from both ends

The strip() method removes whitespace from the start and end of a string.

It does not remove spaces in the middle.

This is useful when you want to clean input from a user or text read from a file.

text = "  hello world  "
cleaned = text.strip()

print(cleaned)

Output:

hello world

Notice that the space between hello and world stays there.

You can also use:

lstrip() to remove whitespace from the left side only
rstrip() to remove whitespace from the right side only

Example:

text = "  hello world  "

print(text.lstrip())
print(text.rstrip())

Output:

hello world  
  hello world

If you want more detail, see the strip() string method.

Use `replace()` to remove all space characters

If you want to remove all normal spaces from a string, use replace(" ", "").

text = "h e l l o   w o r l d"
cleaned = text.replace(" ", "")

print(cleaned)

Output:

helloworld

This works well when you want to remove visible space characters everywhere in the text.

Important: this removes only the normal space character " ".

It does not remove:

tabs (\t)
newline characters (\n)

Example:

text = "hello\tworld\npython code"
cleaned = text.replace(" ", "")

print(repr(cleaned))

Output:

'hello\tworld\npythoncode'

The tab and newline are still there.

To learn more, see the replace() string method or this guide on how to replace text in a string in Python.

Use `split()` and `join()` to remove all kinds of whitespace

If your text may contain spaces, tabs, or newlines, a useful pattern is:

"".join(text.split())

Here is how it works:

split() with no argument splits the string on any whitespace
Whitespace includes spaces, tabs, and newlines
join() puts the pieces back together with no separator

Example:

text = "  hello\tworld \n python  "
cleaned = "".join(text.split())

print(repr(cleaned))

Output:

'helloworldpython'

This removes all whitespace characters, not just normal spaces.

Here is another example:

text = "one   two\tthree\nfour"
parts = text.split()
cleaned = "".join(parts)

print(parts)
print(cleaned)

Output:

['one', 'two', 'three', 'four']
onetwothreefour

This approach is helpful for messy text copied from forms, files, or multiple lines.

If you are new to these methods, see:

Pick the right approach

Use the method that matches your goal:

Use strip() when you only want to trim the start and end
Use replace(" ", "") when you want to remove normal spaces only
Use "".join(text.split()) when the text may contain tabs or line breaks too

Example comparison:

text = "  hello\tworld \n "

print(repr(text.strip()))
print(repr(text.replace(" ", "")))
print(repr("".join(text.split())))

Output:

'hello\tworld'
'hello\tworld\n'
'helloworld'

Each method gives a different result.

Things beginners often get wrong

A few common problems cause confusion here.

Strings are immutable

In Python, strings cannot be changed in place.

String methods return a new string.

This means:

text = "  hello  "
text.strip()

print(repr(text))

Output:

'  hello  '

The original value did not change.

You need to save the result:

text = "  hello  "
text = text.strip()

print(repr(text))

Output:

'hello'

`strip()` does not remove spaces in the middle

This code:

text = "  hello world  "
print(text.strip())

Output:

hello world

The middle space is still there, because strip() only affects the ends.

`replace(" ", "")` does not remove every kind of whitespace

If the string contains tabs or newlines, replace(" ", "") is not enough.

text = "hello\tworld\npython"
print(repr(text.replace(" ", "")))

Output:

'hello\tworld\npython'

Use split() and join() if you need to remove all whitespace types.

Common causes

If your code is not giving the result you expect, these are common reasons:

Using strip() and expecting middle spaces to disappear
Using replace(" ", "") when the string contains tabs or newlines
Forgetting to save the result in a new variable or back to the same variable
Not checking what kind of whitespace is actually in the string

Debugging tips

These quick checks help you see what is really in the string:

print(repr(text))
print(text.strip())
print(text.replace(" ", ""))
print("".join(text.split()))
print(len(text), len(text.strip()))

Why these help:

repr(text) shows hidden characters like \t and \n
strip() lets you test trimming the ends
replace(" ", "") shows what happens when only spaces are removed
"".join(text.split()) shows the result when all whitespace is removed
len() helps you compare before and after

FAQ

How do I remove spaces only from the start and end of a string?

Use strip(). It removes whitespace from both ends of the string.

How do I remove all spaces from a string in Python?

Use replace(" ", "") to remove normal spaces everywhere.

How do I remove tabs and newline characters too?

Use "" .join(text.split()) to remove all whitespace characters:

text = "a\tb\nc d"
cleaned = "".join(text.split())
print(cleaned)

Output:

abcd

Why did my original string not change?

String methods return a new string. Assign the result back to a variable.

text = "  hello  "
text = text.strip()
