I try to sort values in an array in descending order. If I try it in ascending order it works, but when i do it descending I get an error. e = np.array([[5.,3.,8.],[6.,7.,1.],[4.,8.,2.]]) e.sort() result: e = array([[3.,5.,8.],[1...
You could also revert on any other axis, if the array has more than one. To sort in reverse order: >>> arr = np.random.random((1000,1500)) >>> brr = np.reshape(arr, arr.shape[0]*arr.shape[1]) >>> brr.sort() >>> brr = brr[::-1] >>> brr array([ 9.99999960e-01, ...

You can sort a list of strings in reverse order using the sorted() function. For instance, the sorted() function is used to create a new sorted list of strings in reverse order, and the reverse=True parameter is passed to indicate that the sorting should be done in descending order. #...
双调排序(bitonic sort)属于排序网络(Sorting Network)的一种,是一个可并行计算的排序算法。 Bitonic Sort是一个叫Batcher的数学家在1968年提出的。基础是关于双调序列的Batcher定理。 这个排序算法其实实现起来比较简单(当然我说的是递归实现),但是隐藏在其背后的数学原理就不是那么简单就能说明白的了。在参考了维基百...

The sort is in-place (i.e. the list itself is modified) and stable (i.e. the order of two equal elements is maintained). If a key function is given, apply it once to each list item and sort them, ascending or descending, according to their function values. ...
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,表示沿最后一个轴排序。 kind:{'quicksort','mergesort','heapsort','stable'},可选—排序算法。默认为'quicksort'。详细信息如下。
