对 Numpy 数组的每 N 个元素求平均值
在本文中，我们将学习如何找到 NumPy 数组中每 n 个元素的平均值。为了完成我们的任务，我们将使用 NumPy 模块提供的一些内置方法，如下所示:
- numpy. average () Calculate the average value, that is, the sum of all numbers divided by the number of elements.
- numpy. rescale () Take n elements at a time to reshape the array without changing the original data.
- NumPy。 意思是()

Python 3
T8****T10】
```py import numpy as np
converting list to numpy array
givenArray = np.array([6, 5, 4, 3, 2, 1, 9, 8, 7, 12, 11, 10, 15, 14, 13])
here we took 3 as our input
n = 3
calculates the average
avgResult = np.average(givenArray.reshape(-1, n), axis=1)
print("Given array:") print(givenArray)
print("Averaging over every ", n, " elements of a numpy array:") print(avgResult) ```**
