How can I remove a trailing newline in Python?

Question

How can I remove the last character of a string in a newline, In perl I used chomp function what's equivalent to that in Python?

Answer 1

There are several methods to do this I am discussing a few with you:

• Use rstrip

 >>> 'test string\n'.rstrip()

'test string'

   To use this for newlines:

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

'test string \n \r\n\n\r '

• You can also use lstrip() and strip() 

 >>> s = " \n\r\n \n abc def \n\r\n \n "

>>> s.strip()
'qwe   rty'
>>> s.lstrip()
'qwe   rty \n\r\n  \n  '
>>> s.rstrip()
'   \n\r\n  \n  qwe   rty'
