nlcpy.copyto

nlcpy.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.

Parameters

dstndarray

The array into which values are copied.

srcarray_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.

wherearray_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.
