pandas.DataFrame 可以有列表类型列吗? [英] Can pandas.DataFrame have list type column?

问题描述

是否可以创建包含列表类型字段的pandas.DataFrame?

Is it possible to create pandas.DataFrame which includes list type field?

例如，我想将以下 csv 加载到 pandas.DataFrame:

For example, I'd like to load the following csv to pandas.DataFrame:

id,scores
1,"[1,2,3,4]"
2,"[1,2]"
3,"[0,2,4]"

推荐答案

去掉双引号:

id,scores
1, [1,2,3,4]
2, [1,2]
3, [0,2,4]

你应该能够做到这一点:

And you should be able to do this:

query = [[1, [1,2,3,4]], [2, [1,2]], [3, [0,2,4]]]
df = pandas.DataFrame(query, columns=['id', 'scores'])
print df
