How Can I Efficiently Remove Whitespace from Strings in Python?

Eliminating Whitespace in Strings

When dealing with strings, it's often necessary to remove whitespace to improve readability and data consistency. In Python, several methods are available to achieve this.

Trimming Leading and Trailing Whitespace

If you only want to remove whitespace from the beginning and end of a string, use the strip() method:

>>> "  hello  apple  ".strip()
'hello  apple'

Removing All Whitespace Characters

To completely remove all space characters from a string (specifically the "normal" ASCII space character 'U 0020'), use replace():

>>> "  hello  apple  ".replace(" ", "")
'helloapple'

Stripping Whitespace and Leaving a Single Space Between Words

If you want to retain spacing between words while removing all other whitespace, use split() and join():

>>> " ".join("  hello  apple  ".split())
'hello apple'

Completely Removing Whitespace

To remove whitespace completely, change the leading " " in the above join statement to "":

>>> "".join("  hello  apple  ".split())
'helloapple'
