Sometimes I find myself in need of this nice operator that I used back in
the days when I was programming in .NET, essentially an expression
>>> expr ?? instead
should return expr when it `is not None` and `instead` otherwise.
A piece of code that I just wrote, you can see a use case:
def _sizeof(self, context):
if self.totalsizeof is not None:
return self.totalsizeof
else:
raise SizeofError("cannot calculate size")
With the oprator it would just be
def _sizeof(self, context):
return self.totalsizeof ?? raise SizeofError("cannot calculate
size")
pozdrawiam,
