???  They are: 

>>> [x for x in dir('') if x[:1]=='r']
['replace', 'rfind', 'rindex', 'rjust', 'rstrip']

'replace' is clearly distinct from the other (it's not an 'eplace' from the 
right:-).  All others can be read as "from the right" (reading them as
"reverse" is very obviously strained).  Find and Index the rightmost
occurrence, right-justify, strip characters from the right of the string.
