it's like a raw string (prefixed with a r) so there is escaped 
char:

r"\": correct token for a string, terminal " is not escaped
`\`: correct token for a string, terminal ` is not escaped
"\": invalid token for a string, " is escaped

so it's usefull on Windows for example, if a litteral string 
contains a path, instead of

"C:\\folder\\file"

you can type

`C:\folder\file`
