['aa', 'bb', 'cc', 'dd', 'ee', 'ff']
>>> test[-1]               ## 逆向输出
'ff'
>>> test[-2]
'ee'

002、

>>> test = ["aa", "bb", "cc", "dd", "ee", "ff"]
>>> test
['aa', 'bb', 'cc', 'dd', 'ee', 'ff']
>>> test[::1]
['aa', 'bb', 'cc', 'dd', 'ee', 'ff']
>>> test[::-1]                 ## 逆向输出列表
['ff', 'ee', 'dd', 'cc', 'bb', 'aa']
>>> test[::-2]                 ## 逆向间隔输出
