使用df.to_csv()编码错误 [英] Encoding error using df.to_csv()

问题描述

我试图将信息从Twits(屏幕名称，created_at和文本)保存到熊猫DataFrame中，然后将DataFrame另存为csv文件.

I am trying to save information from Twits (screen_name, created_at and text) into a pandas DataFrame and then save DataFrame as a csv file.

我遇到编码错误

import tweepy
from tweepy import OAuthHandler

consumer_key = 'bla'
consumer_secret = 'bla'
access_token = 'bla'
access_secret = 'bla'
auth = OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_secret)
api = tweepy.API(auth)

import pandas as pd
import numpy as np
import datetime
import sys

encoding = sys.stdout.encoding or 'utf-8'
columns = ['Screen_Name', 'Time_Stamp', 'Tweet']
todays_date = datetime.datetime.now().date()
tweetDF = pd.DataFrame(columns=columns)

for tweet in tweepy.Cursor(api.search, q="manhattan", lang="en").items(10):
    lenDF = len(tweetDF)
    tweetDF.loc[lenDF] = [tweet.user.screen_name, tweet.created_at, tweet.text]

tweetDF.to_csv("C:/tweetDF")

这里是错误:

我尝试了各种编码增强功能，但未成功
