使用索引从一个NumPy中删除多个元素传递一个包含所有元素的索引的数组,除了要删除的元素的索引,这将从数组中删除该元素。import numpy as np # numpy array arr = np.array([9, 8, 7, 6, 5, 4, 3, 2, 1]) # index array with index of all the elements, except index = 5. # so element at ...
new_x = np.delete(x, index): Use the np.delete() function to delete the elements from 'x' at the specified indices. The result is a new array 'new_x' with the specified elements removed. Python-Numpy Code Editor: Previous:Write a NumPy program to replace all elements of NumPy array...

我们可以用如下的代码实现这个功能。 importnumpyasnp arr=np.array([0,1,2,3,4,5,6,7,8,9])# 定义一维数组arrresult=np.delete(arr,np.arange(1,arr.size,2))# 删除每隔一个元素,即删除下标为1、3、5……的元素print(result) Python Copy 这段代码中,我们首先定义了一个长度为10的...

convenient way to perform element-wise operations, reshaping, slicing, and broadcasting. The NumPy library also integrates well with other libraries, such as pandas, scikit-learn, and matplotlib. With its rich set of functions, NumPy makes array manipulation and transformation tasks much easier and ...
