As Laurent posted, it's simply a literal double-quote character,
enclosed in single quotes. But for making a quoted string, this isn't
reliable (what if there's a double quote in the string itself?), so
you may want to try repr() which makes a theoretically evalable
string:

>>> x="foo"
>>> print repr(x)
'foo'

>>> x=raw_input()
"Ha ha! 'Tis mine!", he said.
>>> print repr(x)
'"Ha ha! \'Tis mine!", he said.'

In this instance, repr chose to use single quotes, but the same applies.
