copyto
(dst, src, casting='same_kind', where=True)¶ Copies values from one array to another, broadcasting as necessary.
Raises a TypeError if the casting rule is violated, and if
where
is provided, it selects which elements to copy.New in version 1.7.0.
Parameters: dst : ndarray
The array into which values are copied.
src : array_like
The array from which values are copied.
casting : {‘no’, ‘equiv’, ‘safe’, ‘same_kind’, ‘unsafe’}, optional
Controls what kind of data casting may occur when copying.
- ‘no’ means the data types should not be cast at all.
- ‘equiv’ means only byte-order changes are allowed.
- ‘safe’ means only casts which can preserve values are allowed.
- ‘same_kind’ means only safe casts or casts within a kind, like float64 to float32, are allowed.
- ‘unsafe’ means any data conversions may be done.
where : array_like of bool, optional
A boolean array which is broadcasted to match the dimensions of dst, and selects elements to copy from src to dst wherever it contains the value True.
