columns—— (默认)将列名映射为列中的值的列表; records—— 行的列表。每行是一个字典,一行映射到一个值; split—— columns映射到列名,index映射到行索引值,data映射到每行数据组成的列表; index—— 将索引映射到行,每行是一个列映射到值的字典; values—— 数据行构成的列表(每行也是列表)。不包含列...
Combining the results into a data structure. Out of these, the split step is the most straightforward. In fact, in many situations we may wish to split the data set into groups and do something with those groups. In the apply step, we might wish to do one of the following: ...
