How Can I Remove Trailing Newlines from a String in Python?

Removing Trailing Newlines with Python

To remove the trailing newline character from a string in Python, employ the rstrip() method.

Python's rstrip() conveniently removes trailing whitespace, including newlines.

>>> 'test string\n'.rstrip()
'test string'

If you specifically want to remove only newlines, specify it using the following syntax:

>>> 'test string \n \r\n\n\r \n\n'.rstrip('\n')
'test string \n \r\n\n\r '

In addition to rstrip(), Python provides the analogous methods strip() and lstrip(). These methods offer finer control over whitespace removal:

• strip(): Removes both leading and trailing whitespace from a string.
• lstrip(): Removes only leading whitespace.
• rstrip(): Removes only trailing whitespace.

An example showcasing their usage:

>>> s = "   \n\r\n  \n  abc   def \n\r\n  \n  "
>>> s.strip()
'abc   def'
>>> s.lstrip()
'abc   def \n\r\n  \n  '
>>> s.rstrip()
'   \n\r\n  \n  abc   def'
