Python 如何使用wordnet拆分列名并查找字典含义？

我有下面的数据，我正试图得到字典的定义，但它只有在它是一个单词时才起作用。我怎样才能使它与多个单词一起工作

代码：

输出：

pd.DataFrame(tmp).T

                        0    1                               2      3
a plane figure bounded by       the specified day of the month  

Sector: a plane figure bounded by two radii and the included arc of a circle
Community: a group of people living in a particular local area, Name: a language unit by which a person or thing is known
Date: the specified day of the month
Community: a group of people living in a particular local area, Center: an area that is approximately central within some larger region, Point: a geometric element that has position but no extension

第1列和第3列为空，因为“社区名称”和“社区中心点”包含多个单词

期望输出：

                          0                                             1                                         2                                                                   3
Sector: [a plane figure...]   Community: [definition], Name: [definition]    Date: [the specified day of the month]  Community: [definition], Center: [definition], Point: [definition]

输出：

pd.DataFrame(tmp).T

                        0    1                               2      3
