TypeError: object '_sre.SRE_Match' has no attribute '__getitem__'


I'm currently getting this error and don't know what is means. Its a scrapy python project, this is the error I'm seeing:

  File "/bp_scraper/bp_scraper/httpmiddleware.py", line 22, in from_crawler
    return cls(crawler.settings)
  File "/bp_scraper/bp_scraper/httpmiddleware.py", line 12, in __init__
    if parts[1]:
TypeError: '_sre.SRE_Match' object has no attribute '__getitem__'

The code:

import re
import random
import base64
from scrapy import log
class RandomProxy(object):
    def __init__(self, settings):
        self.proxy_list = settings.get('PROXY_LIST')
        f = open(self.proxy_list)

        self.proxies = {}
        for l in f.readlines():
            parts = re.match('(\w+://)(\w+:\[email protected])?(.+)', l)

            if parts[1]:
                parts[1] = parts[1][:-1]

            self.proxies[parts[0] + parts[2]] = parts[1]

    def from_crawler(cls, crawler):
        return cls(crawler.settings)

Thanks in advance for your help!

The result of a re.match call is a SRE_Match object, which does not support the [] operator (a.k.a. __getitem__). I think you want

if parts is not None:
    if parts.group(1):

Unfortunately, parts.group(1) is not mutable, so you'll have to make another variable to hold the changes you want to make to it.
