将列名称分配给csv数据集 [英] Assign columns names to a csv dataset

问题描述

我目前正在处理由以下数据组成的数据集:

I'm currently working on a dataset that consists of the following data:

paper_id, word_attributes, class_label

现在总共有3700个word_attributes列表示一个二进制值. python中是否有一种方法可以用来分配列标题?谢谢.

Now there are a total of 3700 word_attributes columns representing a binary value. Is there a method in python using which I could assign the column headers? Thanks.

推荐答案

您也许可以使用以下命令读取csv文件:

You can perhaps read the csv file using:

a = np.genfromtxt(filename, delimiter=',', dtype=None, names=True)

它将创建一个numpy.recarray，其中每个列都可以通过键(例如a['paper_id'])来调用.当dtype=None时，"dtypes将由每个 列".

it will create a numpy.recarray where each column can be called by a key, like a['paper_id']. When dtype=None, "the dtypes will be determined by the contents of each column, individually".

如@askewchan所建议，您必须传递names=True来保留csv列的原始名称.

as suggested by @askewchan, you have to pass names=True to keep the original names for the csv columns.
