Question

我正在使用Python和Facebook-SDK从一些Facebook页面收集所有评论。

由于我想对这些评论进行情感分析，保存这些文本的最佳方法是什么，以便不需要对文本进行任何更改？

我现在将评论保存为表格，然后保存为CSV文件。

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Admin extends MY_Controller {

 public function index()
 {
    $this->load->view("layouts/header");
    $this->load->view("layouts/navbar");
    $this->load->view("just_organize/administrador/index");
    $this->load->view("layouts/footer");
 }
 public function day_s(){
    $time = date("H");
    $timezone = date("e");
    if ($time < "12") {
        $greeting= "Good morning";
    } else
    if ($time >= "12" && $time < "17") {
        $greeting= "Good afternoon";
    } else
    if ($time >= "17" && $time < "19") {
        $greeting= "Good evening";
    } else
    if ($time >= "19") {
        $greeting= "Good night";
    }
 }
}

但是如果我想读取这个保存的文件，我会收到以下错误：

table.to_csv('file-name.csv')

顺便说一下，我正在使用德语文本。

Answer 1

Have you tried this?

Set default encoder at the top of your code

import sys
reload(sys)
sys.setdefaultencoding("ISO-8859-1")

or

pd.read_csv('file-name.csv', encoding = "ISO-8859-1")

Answer 2

如果你对数据的编码有所了解，你可以简单地使用pandas来读取你的csv，如下所示：

import pandas as pd
pd.read_csv('filename.csv', encoding='encoding')

Answer 3

I would say it really depends on many different factors such as:

Size of the data
What kind of analysis, specifically, are you anticipating that you'll be doing
What format are you most comfortable working with the data

For most of my data munging in python I like to do it in pandas if possible, but sometimes that's not a feasible option given the size of the data. In that case you'd have to think about using something like pyspark. But here is a link to the pandas docs for reference, they have a lot of functionality for reading in all kinds of data: pandas docs
