使用返回值作为 function 参数

Question

I'm trying to use a value returned by one function as the argument value for another function - in this case, getting the page to open in selenium. However, outside of the function it does not recognise the value returned:

def discover(self, terms):
    self.open_browser()
    for term in terms:
        self.search(term)
        time.sleep(2)
        html = BeautifulSoup(self.driver.page_source, 'lxml')
        time.sleep(0.5)
        #self.scroll(html)
        cards = html.find_all('div', class_='styles__UserCardInformation-sc-f909fw-5 jEfkYy')
        #print(cards)
        time.sleep(0.5)
        for card in cards:
            self.open_profile(card)
            self.driver.get(user_profile_url)

The user_profile_url is returned by the open_profile function, ideal to be passed through the driver.get function. However, this doesn't work.

open_profile function

def open_profile(self, card):
    user = card.div.span.a.p.text
    user_link_suffix = card.div.span.a['href']
    user_profile_url = f'https://www.mixcloud.com{user_link_suffix}'
    print(user)
    return user_profile_url

Answer 1

you need to assign the return value before using it

 def discover(self, terms):
self.open_browser()
for term in terms:
    self.search(term)
    time.sleep(2)
    html = BeautifulSoup(self.driver.page_source, 'lxml')
    time.sleep(0.5)
    #self.scroll(html)
    cards = html.find_all('div', class_='styles__UserCardInformation-sc-f909fw-5 jEfkYy')
    #print(cards)
    time.sleep(0.5)
    for card in cards:
        user_profile_url = self.open_profile(card)
        self.driver.get(user_profile_url)

Answer 2

You can either assign the open_profile() to some variable and then pass that to get() or simply...

self.driver.get(self.open_profile(card))
