__setitem__

array.__setitem__(key: int | slice | ellipsis | Tuple[int | slice | ellipsis, ...] | array, value: int | float | bool | array, /) → None

Sets self[key] to value.

Parameters:

• self (array) – array instance.

• key (Union[int, slice, ellipsis, Tuple[Union[int, slice, ellipsis], ...], array]) – index key.

• value (Union[int, float, bool, array]) – value(s) to set. Must be compatible with self[key] (see Broadcasting).

Note

Setting array values must not affect the data type of self.

When value is a Python scalar (i.e., int, float, bool), behavior must follow specification guidance on mixing arrays with Python scalars (see Type Promotion Rules).

When value is an array of a different data type than self, how values are cast to the data type of self is implementation defined.
