1)删除一维数组中的元素 importnumpyasnp arr = np.array([0,1,2,3,4,5])# 删除索引2的元素new_arr = np.delete(arr,2) print(new_arr)# [0 1 3 4 5] 2)删除多个元素 importnumpyasnp arr = np.array([0,1,2,3,4,5])# 删除索引1,3,4的元素new_arr = np.delete(arr, [1,3,4]...
np.delete(a,1, axis=1) array([[4], [6]]) 删除多列 考虑以下二维数组: a = np.array([[1,2,3],[4,5,6],[7,8,9]]) a array([[1,2,3], [4,5,6], [7,8,9]]) 要删除索引 0 和 2 处的列: np.delete(a, [0,2], axis=1) array([[2], [5], [8]]) 注:本文由...
The np.delete() function takes three main arguments: the input array, the index of the element or column to be deleted, and the axis along which to delete. The axis parameter is crucial in this case since we want to delete the column, not just an element. By setting axis=1, we are...
The array is:Array([0] => Rose[2] => Jasmine[3] => Hibiscus[4] => Tulip[5] => Sun Flower[6] => Daffodil[7] => Daisy) As you could see, the index1is missing after we apply theunsetfunction. Usearray_splice()Function to Delete an Element From an Array in PHP ...
code. Allocation like this returns a pointer to the first element, which can be dereferenced to access different members. Finally, when the array is not needed, it should be freed with a specialdeletenotation containing empty square brackets, which guarantees that every element has been ...

选单元就可以实现对单元的删除,同样的,记录一下rpy里的python语句: # delete elemente=p.elements elements=e.getSequenceFromMask(mask=('[#1 ]', ), )part.deleteElement(elements=elements) 乍一看比较乱,但是看多了就习惯了,练习多了,你就知道里面哪些语句是你需要的。这里主要用的函数是deleteElement(),注意...
Python numpy delete用法及代码示例本文简要介绍 python 语言中 numpy.delete 的用法。 用法: numpy.delete(arr, obj, axis=None)返回一个新数组,其中删除了沿轴的子数组。对于一维数组,这将返回那些未返回的条目arr[对象].参数: arr: array_like 输入数组。 obj: 切片、int 或整数数组 指示要沿指定轴删除的...
