В Pycharm есть какой-нибудь ярлык для добавления '>>>' из строк в строке документации для doctest? - PullRequest

После того, как мы скопируем несколько строк кода в строку документации для теста do c, есть ли ярлык для автоматического добавления «>>>» перед кодом?

Например, в следующем docstring, код doctest длинный, очень утомительно вручную добавлять '>>>' для каждой строки .

def iter_leaves_with_another(tree: Mapping, iter_with: Mapping, default: Callable = dict):
    """
    Iterates through the leaves of the tree (represented by nested mappings), together with another mapping.
    This method can be applied to construct a dictionary with the same structure as the `tree`, with some transformations on the values.

    For example,
    >>> import utilx.dict_ext as dx
    >>> reconstruct = {}
    >>> for d, k, v in dx.iter_leaves_with_another({
    >>>     'a': 1,
    >>>     'b': {'b1': 2,
    >>>           'b2': {'b21': 3,
    >>>                  'b22': 4,
    >>>                  'b23': {'b231': 5}}},
    >>>     'c': 6,
    >>>     'd': {'d1': 7,
    >>>           'd2': 8,
    >>>           'd3': {},
    >>>           'd4': {'d41': 9,
    >>>                  'd42': 10}}
    >>> }, iter_with=reconstruct, default=dict):
    >>>     d[k] = v + 1
    >>>
    >>> # the following prints out the same tree structure, with all values being added by 1.
    >>> # i.e. {'a': 2, 'b': {'b1': 3, 'b2': {'b21': 4, 'b22': 5, 'b23': {'b231': 6}}}, 'c': 7, 'd': {'d1': 8, 'd2': 9, 'd3': {}, 'd4': {'d41': 10, 'd42': 11}}}
    >>> print(reconstruct)

    :param iter_with: iterate through the leaves of the `tree` together with this mapping.
    :param default: a callable that returns an object assigned to a key when it is not found in the `iter_with`.
    :return: an iterator; yields a three-tuple at a time: 1) a sub-mapping in `iter_with` that corresponds to the current level in the `tree` being iterated through; 2) the key; 3) the value.
