如何修复UnicodeEncodeError：？

Question

所以我试图从本地网站上删除有关主板的数据。

import bs4
import os
import requests

from bs4 import BeautifulSoup as soup

os.chdir('E://')
os.makedirs('E://scrappy', exist_ok=True)
myurl = "https://www.example.com"
res = requests.get(myurl)
page = soup(res.content, 'html.parser')
containers = page.findAll("div", {"class": "content-product"})
filename = 'AM4.csv'
f = open(filename, 'w')
headers = 'Motherboard_Name, Price\n'
f.write(headers)

for container in containers:
    Product = container.findAll("div", {"class": "product-title"})
    Motherboard_Name = Product[0].text.strip()
    Kimat = container.findAll("span", {"class": "price"})
    Price = Kimat[0].text
    print('Motherboard_Name' + Motherboard_Name)
    print('Price' + Price)
    f.write(Motherboard_Name + "," + Price.replace(",", "") + "\n")
f.close() print("done")

但是当我运行此代码时出现错误

UnicodeEncodeError：'charmap'编解码器无法对位置45中的字符'\ u20b9'进行编码：字符映射到

我该如何解决这个问题？

编辑::所以我通过添加encoding =“utf-8”修复了unicode错误（正如这里提到的那样python 3.2 UnicodeEncodeError: 'charmap' codec can't encode character '\u2013' in position 9629: character maps to <undefined>）（open（filename，'w'，encoding =“utf-8”） ）它似乎做了工作但是在csv文件中得到价格之前的字符（â，¹）...我该如何解决这个问题？

Answer 1

使用csv模块管理CSV文件，并使用utf-8-sig for Excel正确识别UTF-8。打开文件时，请确保按照newline=''文档使用csv。

示例：

import csv

filename = 'AM4.csv'
with open(filename,'w',newline='',encoding='utf-8-sig') as f:
    w = csv.writer(f)
    w.writerow(['Motherboard_Name','Price'])
    name = 'some name'
    price = '\u20b95,99'
    w.writerow([name,price.replace(',','')])
