qiskit.opflow.primitive_ops.PauliSumOp.from_list¶

classmethod PauliSumOp.from_list(pauli_list, coeff=1.0, dtype=<class 'complex'>)[source]¶

Construct from a pauli_list with the form [(pauli_str, coeffs)]

Parameters

pauli_list (List[Tuple[str, Union[complex, ParameterExpression]]]) – A list of Tuple of pauli_str and coefficient.
coeff (Union[complex, ParameterExpression]) – A coefficient multiplying the primitive.
dtype (type) – The dtype to use to construct the internal SparsePauliOp. Defaults to complex.

Return type

PauliSumOp

Returns

The PauliSumOp constructed from the pauli_list.
