如何使用Python检查CSV是否具有标头? [英] How to check if a CSV has a header using Python?

问题描述

我有一个CSV文件，我想检查第一行中是否只有字符串(即标题).我试图避免使用任何其他功能，例如pandas等.我想我将使用if语句，例如row [0]是字符串打印，这是CSV，但我真的不知道该怎么做: -S有什么建议吗?

I have a CSV file and I want to check if the first row has only strings in it (ie a header). I'm trying to avoid using any extras like pandas etc. I'm thinking I'll use an if statement like if row[0] is a string print this is a CSV but I don't really know how to do that :-S any suggestions?

推荐答案

Python具有内置的 CSV模块可能会有所帮助.例如

Python has a built in CSV module that could help. E.g.

import csv
with open('example.csv', 'rb') as csvfile:
    sniffer = csv.Sniffer()
    has_header = sniffer.has_header(csvfile.read(2048))
    csvfile.seek(0)
    # ...
