一個簡單的Python爬蟲+寫入文本

import os
import requests
from bs4 import BeautifulSoup

# 獲取HTML文檔
def get_html(url):
 response = requests.get(url)
 response.encoding = 'uft-8'
 return response.text

# 獲取笑話
def get_joke(html):
 soup = BeautifulSoup(html,'lxml')

 abc = ''
 num = 0
 for link in soup.find_all("div", class_="content"):
 # for i in range(10):
 # joke_content = soup.select('div.content')[i].get_text()
 num = num + 1
 abc += "--------" + str(num) + link.get_text()
 return abc

# 將笑話寫入txt
# ls = os.linesep

def writeJoke(joke):
 while True:
 filename = input('文件名：')
 if os.path.exists(filename):
 print("錯誤:'%s' 該文件已存在" % filename) # 是否存在

 else:
 break

 fobj = open(filename, 'w') #寫入文本

 fobj.write(joke)
 # fobj.writelines(['%s%s' % (x, ls) for x in all]) #每一個字符后面都會換行
 fobj.close()
 print('寫入成功！')

url_joke = "https://www.qiushibaike.com"
html = get_html(url_joke)
joke = get_joke(html)
writeJoke(joke)
# print(joke)
