Python脚本出现IndentationError错误，无法正确调整代码缩进求助

Python缩进错误修正方案 #

你代码的缩进问题主要来自两处：

• get_proxies() 函数的return proxies语句之后的业务代码缩进错误，被包含在函数内部永远不会执行，需要取消多余缩进放到全局执行层级
• 循环、try-except代码块内的缩进空格数不统一，不同层级代码混用多空格缩进，统一调整为4空格为一个缩进层级即可。

开发时建议开启编辑器空白字符显示功能，可直观区分空格、制表符，快速排查缩进类问题

修正后完整代码 #

from lxml.html import fromstring
import requests
from itertools import cycle
import traceback

def get_proxies():
    url = 'https://free-proxy-list.net/'
    response = requests.get(url)
    parser = fromstring(response.text)
    proxies = set()
    for i in parser.xpath('//tbody/tr')[:10]:
        if i.xpath('.//td[7][contains(text(),"yes")]'):
            proxy = ":".join([i.xpath('.//td[1]/text()')[0], i.xpath('.//td[2]/text()')[0]])
            proxies.add(proxy)
    return proxies

proxies = get_proxies()
proxy_pool = cycle(proxies)
url = 'https://httpbin.org/ip'
for i in range(1,11):
    # Get a proxy from the pool
    proxy = next(proxy_pool)  
    print("Request #%d"%i)
    try:
        response = requests.get(url,proxies={"http": proxy, "https": proxy})
        print(response.json())
    except:
        print("Skipping. Connnection error")
