程式碼如下：

import requests
from bs4 import BeautifulSoup

# 獲取網站資料
def get_data(url):
    headers = {
        'user-agent': 'Mozilla/5.0'
    }
    html = requests.get(url, headers)
    html.encoding = 'utf-8'
    return html.text
# 解析網站資料
def parse_dara(html):
    soup = BeautifulSoup(html, '
 
html.parser')
    '''
        protocol = soup.find_all(attrs={'data-title': '型別'})
        ip = soup.find_all(attrs={'data-title': 'IP'})
        port = soup.find_all(attrs={'data-title': 'PORT'})
    '''
    # 協議 地址 埠
    protocol = soup.select('#list > table > tbody > tr > td:nth-child(4)
 
')
    ip = soup.select('#list > table > tbody > tr > td:nth-child(1)')
    port = soup.select('#list > table > tbody > tr > td:nth-child(2)')
    data = []       # 存放代理連結
    for i in range(0, len(ip)):          # 要求len(ip), len(port) len(protocol)的值一樣
        temp = protocol[i].get_text()+'
 
://'+ip[i].get_text()+':'+port[i].get_text()     # 拼接成url
        data.append(temp)                                                               # 拼接後的資料，加入到列表
    return data

# 儲存資料
def save_data(data):
    for item in data:
        with open('output\\'+proxy, 'a+') as f:
            f.write(item)
            f.write('\n')

if __name__=='__main__':
    proxy = 'proxy.txt'
    url = 'https://www.kuaidaili.com/free/inha/1'
    html = get_data(url)
    data = parse_dara(html)
    save_data(data)
    print('爬蟲結束')

結果：

只爬了第一頁的代理，其他幾頁，加個迴圈就解決了。
