In [3]: help(np.sort) Help on function sortinmodule numpy.core.fromnumeric: sort(a, axis=-1, kind='quicksort', order=None) Return a sorted copy of an array. Parameters----------a : array_like Array to be sorted.
print("Original numpy array:") print(data) 3. 按某一列排序 使用numpy库的sort函数可以实现按某一列排序。以下是按“Age”列排序的示例: #按Age列排序 sorted_data = np.sort(data, order='Age') print("\nNumpy array sorted by Age:") print(sorted_data) 四、总结 在Python中,按某一列排序有多...

Numpy是用于科学计算的Python基础库。与vanilla Python一样,有两种执行方式,一种是变异数组,另一种是数据的复制。 my_array.sort()改变有序数组并返回已排序数组。 np.sort(my_array)返回已排序数组的副本,因此原始数组不会改变。 以下是可选参数。 axis:int,可选—要排序的轴。默认值为-1,表示沿最后一个轴...
