Functions#

sampo.utilities.collections_util.flatten(xs: collections.abc.Iterable[list[T] | T]) → collections.abc.Iterable[T]#

Returns a generator which should flatten any heterogeneous iterable

Parameters:

xs –

Returns:

sampo.utilities.collections_util.build_index(items: collections.abc.Iterable[T], key_getter: Callable[[T], K], value_getter: Callable[[T], V] = lambda x: ...) → dict[K, V]#
Parameters:

  • items – an iterable to index

  • key_getter – a function that should retrieve index key from item

  • value_getter – a function that should retrieve index value from item
