TypeError:需要一个类似字节的对象,而不是“str”
在执行以下 python 代码以将 HTML 表数据保存在 Csv 文件中时出现上述错误。不知道如何获得rideup.pls帮助我。
import csv import requests from bs4 import BeautifulSoup url='http://www.mapsofindia.com/districts-india/' response=requests.get(url) html=response.content soup=BeautifulSoup(html,'html.parser') table=soup.find('table', attrs={'class':'tableizer-table'}) list_of_rows=[] for row in table.findAll('tr')[1:]: list_of_cells=[] for cell in row.findAll('td'): list_of_cells.append(cell.text) list_of_rows.append(list_of_cells) outfile=open('./immates.csv','wb') writer=csv.writer(outfile) writer.writerow(["SNo", "States", "Dist", "Population"]) writer.writerows(list_of_rows)
在最后一行之上。
您使用的是 Python 2 方法而不是 Python 3。
改变:
outfile=open('./immates.csv','wb')
至:
outfile=open('./immates.csv','w')
你会得到一个带有以下输出的文件:
SNo,States,Dist,Population 1,Andhra Pradesh,13,49378776 2,Arunachal Pradesh,16,1382611 3,Assam,27,31169272 4,Bihar,38,103804637 5,Chhattisgarh,19,25540196 6,Goa,2,1457723 7,Gujarat,26,60383628 .....
在 Python 3 中,csv 以文本模式接受输入,而在 Python 2 中,它以二进制模式接受输入。
编辑添加
这是我运行的代码:
url='http://www.mapsofindia.com/districts-india/' html = urllib.request.urlopen(url).read() soup = BeautifulSoup(html) table=soup.find('table', attrs={'class':'tableizer-table'}) list_of_rows=[] for row in table.findAll('tr')[1:]: list_of_cells=[] for cell in row.findAll('td'): list_of_cells.append(cell.text) list_of_rows.append(list_of_cells) outfile = open('./immates.csv','w') writer=csv.writer(outfile) writer.writerow(['SNo', 'States', 'Dist', 'Population']) writer.writerows(list_of_rows)
