numpy.copyto¶
- numpy.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
whereis provided, it selects which elements to copy.New in version 1.7.0.
- 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.
