我在另一个类中调用一个方法,得到以下错误。这是声明定义方法的类:
from web import Web
import ast
class WebCrawler:
web = Web()
def crawl(self):
root = self.root()
URL = ast.literal_eval(self.get(root))
return URL
这个类称之为:
from web import Web
from crawler import WebCrawler
web = Web()
crawler = WebCrawler()
urls = crawler.crawl(web)
print(urls)
Traceback (most recent call last):
File "/home/onur/Desktop/web-crawler/test-run.py", line 6, in <module>
urls = crawler.crawl(web)
TypeError: crawl() takes 1 positional argument but 2 were given
