What

Its just a unicode string.
The string constants in Python can be prefixed with a u. Instead of
building a string object for that constant, the interpreter will build a
Unicode string object.

You can also prefix them with r, to make the interpreter ignore escape
codes.
For example:

a
b

And you can use the combined ur prefix.
