`<object>` is the same as repr(<object>). I'm pretty sure the backtick
operator has been removed from 3.0.

In the context of the code sample you posted, it appears to be used to
convert the result of x*x into a string for the join method, but I
personally think it's a misuse of repr() and think a call to str()
would be more appropriate:

>>> ' '.join((str(x * x) for x in range(1,6)))
'1 4 9 16 25'
