Sorting a NumPy array in descending order sorts the elements from largest to smallest value. You can use the syntaxarray[::-1]to reverse the array. # Sort array in descending orderarray=np.sort(array)[::-1]print("Sorted descending order:\n",array)# Output# Sorted descending order:# [...
按降序排列numpy列表的元素 你想要的是你的元素按降序排列的等级。 a = np.array([2,3,1,4,5])sorted_indices = np.argsort(-a)ranks = np.empty_like(sorted_indices)ranks[sorted_indices] = np.arange(len(a)) And result: >>> ranksarray([3, 2, 4, 1, 0]) 如何按降序排列字符串向量?
