我寫了這段代碼，但出現錯誤
from lxml.html import fromstring
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")]'):
#Grabbing IP and corresponding PORT
proxy = ":".join([i.xpath('.//td[1]/text()')[0], i.xpath('.//td[2]/text()')[0]])
proxies.add(proxy)
return proxies
錯誤是
File "check.py", line 13
return proxies
^
IndentationError: unexpected indent
無法理解錯誤，但也許行距與此有關

你的縮進很差。
import requests
from lxml.html import fromstring
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")]'):
#Grabbing IP and corresponding PORT
proxy = ":".join([i.xpath('.//td[1]/text()')[0], i.xpath('.//td[2]/text()')[0]])
proxies.add(proxy)
return proxies

Python 對制表符很敏感，而您忘記匯入requests包：
from lxml.html import fromstring
import requests
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")]'):
#Grabbing IP and corresponding PORT
proxy = ":".join([i.xpath('.//td[1]/text()')[0], i.xpath('.//td[2]/text()')[0]])
proxies.add(proxy)
return proxies
