Tags

Numpy's ptp(~) method returns the range (i.e. maximum - minimum) along the specified axis. Note that ptp stands for "peak to peak".

Parameters

1. a | array-like

The input array.

2. axislink | None or int | optional

The axis along which to compute the range. For 2D arrays, the allowed values are as follows:

Axis

Meaning

0

Compute the range column-wise

1

Compute the range row-wise

None

Compute the range on a flattened array

By default, axis=None.

3. out | Numpy array | optional

Instead of creating a new array, you can place the computed result into the array specified by out.

Return value

If q is a scalar, then a scalar is returned. Otherwise, a Numpy array is returned.

Examples

Computing the range of a 1D array

To compute the range of a 1D array:

np.ptp([5,6,7,8,9])
4

Computing the range of a 2D array

Suppose we have the following 2D array:

a = np.array([[5,6],[7,8]])
a
array([[5, 6],
[7, 8]])

Flattened

To compute the range of the flattened version of a:

np.ptp(a)
3

Column-wise

To compute the range column-wise:

np.ptp(a, axis=0)
array([2, 2])

Row-wise

To compute the range row-wise:

np.ptp(a, axis=1)
array([1, 1])
