As always, the standard advice is to use the os.path module both
to construct and deconstruct pathnames, since this handles architectural
differences correctly in a platform-independent way!
I've had trouble fully understanding raw string literals. Since
can I assume
a) There is no way to write a string literal containing
only an apostrophe and a double-quote; and
b) A string literal containing only a single backslash
must be written as "\\"?
