<s>[INST] How can I remove (chomp) a newline in Python? What is the Python equivalent of Perl's chomp function, which removes the last character of a value?
 [/INST] Try the rstrip method.
>>> 'test string\n'.rstrip()
'test string'

Note that Python's rstrip method strips all kinds of trailing whitespace by default, not just one newline as Perl does with chomp. To strip only newlines:
>>> 'test string \n\n'.rstrip('\n')
'test string '

There is also the lstrip and strip methods.
>>> s = " \n  abc   def   "
>>> s.strip()
'abc   def'
>>> s.rstrip()
' \n  abc   def'
>>> s.lstrip()
'abc   def   '
>>>
