Typing: Compatibility

Since typing still significantly changes across different Python versions, all the special cases are handled here.

class tad_libcint.typing.compat.Callable

Bases: object

class tad_libcint.typing.compat.Sequence

Bases: Reversible, Collection

All the operations on a read-only sequence.

Concrete subclasses must override __new__ or __init__, __getitem__, and __len__.

count(value) → integer -- return number of occurrences of value

index(value[, start[, stop]]) → integer -- return first index of value.

Raises ValueError if the value is not present.

Supporting start and stop arguments is optional, but recommended.
