如何制作所有可能的序列，但像 n-grams 这样的方法

Question

新手问。 我想做一个这样的程序：

example: text = 'I playing basketball today'

2 gram > 'I playing', 'I basketball', 'I today',
         'playing I', 'playing basketball', 'playing today',
         'basketball I', 'basketball playing', 'basketball today',
         'today I', 'today playing', 'today basketball'
3 gram > 'I playing basketball', 'I basketball today', 'I playing today',
         'playing I basketball', 'playing I today', 'playing basketball today',
         'basketball I playing', 'basketball I today', 'basketball playing today', etc.
etc gram.

我使用 n-gram 得到这样的结果

2 gram > 'I play', 'play basketball', 'basketball today'
3 gram > 'I play basketball', 'play basketball today'

如何操作像一个例子？ 或者这有可能吗？

我不知道它是什么方法名，所以我在谷歌上找不到

抱歉这个令人困惑的问题，感谢您的帮助。
