Python类不接受任何参数，给定3（使用_uinit__;）

Question

我正在尝试从youtube教程等创建一个网络爬虫

我面临一个问题，我有一个不接受参数的类（其他类接受参数，结构或多或少相同）

类（crawler.py）。我使用的是__init__，这里有3个参数

class Crawler:
    # class variables are shared among all crawler instances
    project_name = ''
    home_url = ''
    site_domain = ''
    # use set to speed up read/write process
    file_queue = ''
    queue = set()
    # use set to speed up read/write process
    file_crawled = ''
    crawled = set()

    def __init__(self, project_name, home_url, site_domain):
        Crawler.project_name = project_name
        Crawler.home_url = home_url
        Crawler.site_domain = site_domain
        Crawler.file_queue = Crawler.project_name + '/links_on_queue.txt'
        Crawler.file_crawled = Crawler.project_name + '/links_crawled.txt'
        self.starter(Crawler.site_domain)
        self.crawl_page('first_crawler', Crawler.home_url)

调用它的位置，在最后一行（main.py）

import threading
from queue import Queue
# import from files
from crawler import Crawler
from domain_finder import *
from general_crawler_functions import *

# like multiple group members doing different parts, the program
# creates multiple thread that works simultaneously

PROJECT_NAME = 'Demoblaze'
HOME_URL = 'https://www.demoblaze.com/'
DOMAIN_NAME = get_domain(HOME_URL)
FILE_QUEUE = PROJECT_NAME + '/links_on_queue.txt'
FILE_CRAWLED = PROJECT_NAME + '/links_crawled.txt'
THREAD_COUNT = 4
# queue of threads
queue = Queue()
Crawler(PROJECT_NAME, HOME_URL, DOMAIN_NAME)

错误表示该类不接受任何参数，给出了3个参数

如果有帮助的话，我正在windows上使用PyCharm社区

在main.py中，您已经从Crawler导入了Crawler

from crawler import Crawler

您应该导入您自己实现的爬虫程序。 使用

import Crawler

而不是

Crawler from crawler
