Python - 缺少 1 个参数，即使我提供了它

Question

我正在提供论据，但仍然收到错误。我什至尝试将其作为字符串提供。错误：C:\anaconda3\python.exe C:/Test/browser_automation/app.pyEnter the author you'd like quotes from: testtestTraceback (most recent call last):  File "C:/Test/browser_automation/app.py", line 14, in <module>    page.select_author(author)TypeError: select_author() missing 1 required positional argument: 'author_name'Process finished with exit code 1app.pyfrom selenium import webdriverfrom pages.quotes_page import QuotesPagechrome = webdriver.Chrome(executable_path="c:\\Test\\chromedriver.exe")chrome.get('http://quotes.toscrape.com/search.aspx')page = QuotesPage(chrome)author = input("Enter the author you'd like quotes from: ")print(author)page.select_author(author) ## Still reports error#page.select_author('author')  ## Tried it as a string as well and it still reports error.quote_page.py部分内容：    @property    def select_author(self, author_name: str):        self.author_dropdown.select_by_visible_text(author_name)quote_page.py 完整文件：from typing import Listfrom selenium.webdriver.support.ui import Selectfrom locators.quotes_page_locators import QuotesPageLocatorsfrom parsers.quote import QuoteParserclass QuotesPage:    def __init__(self, browser):        self.soup = browser    @property    def quotes(self) -> List[QuoteParser]:        # locator = QuotesPageLocators.QUOTE        # quote_tags = self.browser.select(locator)        # return [QuoteParser(e) for e in quote_tags]        # return [QuoteParser(e) for e in self.soup.select(QuotesPageLocators.QUOTE)]        return [            QuoteParser(e) for e in self.browser.find_elements_by_css_selector(                QuotesPageLocators.QUOTE            )        ]

Property ( @property) 方法不能接受任何参数

因此，将您的财产从

@property
def select_author(self, author_name: str):
   self.author_dropdown.select_by_visible_text(author_name)

到

def select_author(self, author_name: str):
    self.author_dropdown.select_by_visible_text(author_name)
