Question

我正在尝试将信息从Twits（screen_name，created_at和text）保存到pandas DataFrame中，然后将DataFrame保存为csv文件。

我收到编码错误

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")

这里的错误：

UnicodeEncodeError: 'ascii' codec can't encode character u'\u2666' in position 7: ordinal not in range(128)

我尝试了各种编码增强功能，但未成功

我找到了解决问题的方法并希望分享：

radiobutton .t.r1 -text "Default" -variable reptype -value 0
radiobutton .t.r2 -text "Custom" -variable reptype -value 1
.t.r1 select    

place .t.r1 -x 20 -y 30
place .t.r2 -x 20 -y 50

entry .t.ecustom -width 70 
place .t.ecustom -x 100 -y 50

if { $reptype == 0 } {
    .t.ecustom configure -state normal
} elseif { $reptype == 1 } {
    .t.ecustom configure -state disabled
}

使用df.to_csv（）编码错误
