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...
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...

Usingarray_diff()function Useunset()Function to Delete an Element From an Array in PHP The built-in functionunset()is used to delete the value stored in a variable. It is only applicable to the local variables. It does not reflect its behavior on global variables. We can use this functio...
ids are optional N-size numpy array of integer labels for all elements in data. If index already has the elements with the same labels, their features will be updated. Note that update procedure is slower than insertion of a new element, but more memory- and query-efficient. replace_dele...
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 ...
