Python使用URL给出错误读取CSV文件

Question

I am trying to read a CSV file using the requests library but I am having issues.

import requests
import csv

url = 'https://storage.googleapis.com/sentiment-analysis-dataset/training_data.csv'
r = requests.get(url)
text = r.iter_lines()
reader = csv.reader(text, delimiter=',')

I then tried

for row in reader:
  print(row)

but it gave me this error:

Error: iterator should return strings, not bytes (did you open the file in text mode?)

How should I fix this?

Answer 1

What you probably want is:

text = r.iter_lines(decode_unicode=True)

This will return a strings -iterator instead of a bytes -iterator. (See here for documentation.)
