pandas 在表中读取而没有标题 [英] Pandas read in table without headers

问题描述

我如何使用熊猫读取.csv文件(没有标题)，并且只需要一部分列(例如总共20列中的第4和第7)，如何读取?我似乎无法执行usecols

How can I read in a .csv file (with no headers) and when I only want a subset of the columns (say 4th and 7th out of a total of 20 columns), using pandas? I cannot seem to be able to do usecols

推荐答案

为了读取没有头的csv，仅对于某些列，您需要将参数header=None和usecols=[3,6]传递给第4列和第7列:

In order to read a csv in that doesn't have a header and for only certain columns you need to pass params header=None and usecols=[3,6] for the 4th and 7th columns:

df = pd.read_csv(file_path, header=None, usecols=[3,6])
