如何将一个 function 的 output 用于另一个 function？

Question

I was making the code to extract information from the website.

And I wanted it to make for simple and try to organized in some function.

Now, I have a problem with using output of one function for another one.

def last_indeed_page():
    indeed_info = requests.get(url)
    indeed_soup = BeautifulSoup(indeed_info.text, "html.parser")
    pagination = indeed_soup.find("ul", {"class": "pagination-list"})
    pages = pagination.find_all("li")
    a = []
    for page in pages[:-1]:
        a.append(int(page.get_text()))
    last_page = a[-1]
    return last_page

I want to use this output last_page in next function.

def extract_indeed_job(last_page):
    jobs = []
    for n in range(last_page):
        print(f"Indeed scraping page:{n+1}")
        result = requests.get(f"{url}&start={n*LIMIT}")
        result_soup = BeautifulSoup(result.text, "html.parser")
        results = result_soup.find_all("a", {"class": "tapItem"})
        for result in results:
            job = extract_job(result)
            jobs.append(job)
        print(jobs)

extract_indeed_job(last_page)

But, the output of this functions is nothing. It doesn't give me a error but just nothing.
Which part do I have to change?

Answer 1

You have 2 functions: last_indeed_page() , extract_indeed_job(last_page) ; and the output of last_indeed_page needs to be sent to extract_indeed_job .

There are 2 ways to do that.

1. you can either create a variable and then call the function:

last_page_variable = last_indeed_page()
extract_indeed_job(last_page_variable)

2. you can directly call the last_indeed_page function inside the extract_indeed_job function so that the value returned by the last_indeed_page function is passed into extract_indeed_job

extract_indeed_job(last_indeed_page())
