numpy.divmod#
- numpy.divmod(x1,x2,[out1,out2,]/,[out=(None,None),]*,where=True,casting='same_kind',order='K',dtype=None,subok=True[,signature])=<ufunc'divmod'>#
Return element-wise quotient and remainder simultaneously.
np.divmod(x,y)is equivalent to(x//y,x%y), but fasterbecause it avoids redundant work. It is used to implement the Pythonbuilt-in functiondivmodon NumPy arrays.- Parameters:
- x1array_like
Dividend array.
- x2array_like
Divisor array.If
x1.shape!=x2.shape, they must be broadcastable to a commonshape (which becomes the shape of the output).- outndarray, None, or tuple of ndarray and None, optional
A location into which the result is stored. If provided, it must havea shape that the inputs broadcast to. If not provided or None,a freshly-allocated array is returned. A tuple (possible only as akeyword argument) must have length equal to the number of outputs.
- wherearray_like, optional
This condition is broadcast over the input. At locations where thecondition is True, theout array will be set to the ufunc result.Elsewhere, theout array will retain its original value.Note that if an uninitializedout array is created via the default
out=None, locations within it where the condition is False willremain uninitialized.- **kwargs
For other keyword-only arguments, see theufunc docs.
- Returns:
- out1ndarray
Element-wise quotient resulting from floor division.This is a scalar if bothx1 andx2 are scalars.
- out2ndarray
Element-wise remainder from floor division.This is a scalar if bothx1 andx2 are scalars.

The
divmodfunction can be used as a shorthand fornp.divmodonndarrays.>>>x=np.arange(5)>>>divmod(x,3)(array([0, 0, 0, 1, 1]), array([0, 1, 2, 0, 1]))
