使用最后2个空格分割字符串

Question

用于单词拆分

value = "HELLO HOW ARE YOU WHAT ARE YOU DOING"
result = value.split(" ",2)

>> output will be:['HELLO','HOW', 'ARE YOU WHAT ARE YOU DOING']

但是如果我想要这样的结果

output: ['HELLO HOW ARE YOU WHAT ARE' ,'YOU' ,'DOING']

Answer 1

使用rsplit

value = "HELLO HOW ARE YOU WHAT ARE YOU DOING"
result = value.rsplit(" ", 2)
print(result) # ['HELLO HOW ARE YOU WHAT ARE', 'YOU', 'DOING']

Answer 2

只需使用rsplit代替split。

In[7]: s.rsplit(" ", 2)
Out[7]: ['HELLO HOW ARE YOU WHAT ARE', 'YOU', 'DOING']
