tr() is not a standard part of Python. My guess is that it is a
wrapper function that helps with localization.
Raw strings are a syntactic construct, i.e. they exist only in source
code as an instruction to the parser. There is no such thing as a raw
string at runtime, so there is no function to create one.

You have to find where tr() is being imported. From PyShell type
that should print the name of the module containing tr().
