rstrip() removes whitespace, newline characters, tab characters, and carrige
return characters (\n \t \r respectively) on the tail of a string.
Or it can be used with an input parameter to remove all instances of that
parameter from the tail of a string.
ex:
stringy = "i am helpful \t\t\t\t\n\n "
stringy = stringy.rstrip()
print stringy
stdout: "i am helpful"
or:
stringy = "my favorite number is 8000000000000000000000"
stringy = stringy.rstrip('0')
print stringy
stdout: "my favorite number is 8"
pretty simple method, helpful for parsing out formatting characters from
scraped content from webpages.
