r is the way of making a string "raw". This means that escape characters will not be interpreted. Here is an example that should make it clear. >>> foo = "This is \t me" >>> print foo This is me >>> foo = r"This is \t me" >>> print foo This is \t me >>> Since slashes are used often for writing regexps, it's useful to make the strings raw.
