  • This class is similar to cirq.Zip but repeats the last value if the combined sweeps are not the same length.

Can this go into cirq.study? Seems generally useful and not specific to cirq_google

As it is, both sweep3 == sweep4 and hash(sweep3) == hash(sweep4) evaluate to True.
Perhaps we need to use a strict type(other) is Zip in the Zip.__eq__ function

Cirq/cirq-core/cirq/study/sweeps.py

Lines 294 to 297 in 58d0205

def __eq__(self, other):
if not isinstance(other, Zip):
return NotImplemented
return self.sweeps == other.sweeps

and insert ZipLongest or a similar type-marker to the hashed tuple at

Cirq/cirq-core/cirq/study/sweeps.py

Lines 364 to 365 in 58d0205

def __hash__(self) -> int:
return hash(tuple(self.sweeps))

Changed to use 'is not Zip' and also changed the test to use Cirq's equality tester.

Looks good, but I noticed yet another corner case we should clean up.
