Python实现数组逆向输出

#!/usr/bin/pythonarr = [1, 2, 3, 4, 5]def Reverse(arr):    n = len(arr)    print(arr)    for i in range(n):        for j in range(n-i-1):            tmp = arr[j+1]            arr[j+1] = arr[j]            arr[j] = tmp        print(arr)def Reverse2(arr):    n = len(arr)    print(arr)    for i in range(n / 2):        arr[i],arr[n-i-1] = arr[n-i-1],arr[i]        print(arr)
