- qupulse.utils.checked_int_cast(x: Union[float, int, numpy.ndarray], epsilon: float = 1e-06) int [source]¶
- qupulse.utils.forced_hash(obj) int [source]¶
Try to produce a hash from obj by nested conversions to hashable types.
Mapping -> frozendict AbstractSet -> frozenset ndarray -> bytes or nested tuples Sequence -> tuple
- qupulse.utils.is_integer(x: numbers.Real, epsilon: float = 1e-06) bool [source]¶
- qupulse.utils.isclose(a, b, *, rel_tol=1e-09, abs_tol=0.0)¶
Determine whether two floating point numbers are close in value.
- rel_tol
maximum difference for being considered “close”, relative to the magnitude of the input values
- abs_tol
maximum difference for being considered “close”, regardless of the magnitude of the input values
Return True if a is close in value to b, and False otherwise.
For the values to be considered close, the difference between them must be smaller than at least one of the tolerances.
-inf, inf and NaN behave similarly to the IEEE 754 Standard. That is, NaN is not close to anything, even itself. inf and -inf are only close to themselves.
- qupulse.utils.pairwise(iterable: Iterable[qupulse.utils._T]) Iterator[Tuple[qupulse.utils._T, qupulse.utils._T]] ¶
s -> (s0,s1), (s1,s2), (s2, s3), …
- Parameters
iterable – Iterable to iterate over pairwise
- Returns
An iterable that yields neighbouring elements
- qupulse.utils.replace_multiple(s: str, replacements: Mapping[str, str]) str [source]¶
Replace multiple strings at once. If multiple replacements overlap the precedence is given by the order in replacements.
For pyver >= 3.6 (otherwise use OrderedDict) >>> assert replace_multiple(‘asdf’, {‘asd’: ‘1’, ‘asdf’, ‘2’}) == ‘asd1’ >>> assert replace_multiple(‘asdf’, {‘asdf’: ‘2’, ‘asd’, ‘1’}) == ‘2’
