Writing functions inside classes in Python

Question

I'm new to writing classes in Python and had a quick question. Here is some code below.

class Parse_profile():

  def __init__(self, page):
    self.page = page

  def get_title(self):
    list_of_titles = []
    for title in self.page.find_all(.....):
      list_of_titles.append(title.get_text())
    return list_of_titles

  def get_companies(self):
    list_of_companies = []
    for company in self.page.find_all(.....):
      list_of_companies.append(company)
    return list_of_companies

I want to create a third function that will take in both list_of_companies and list_of_titles (and more later on) and combine them into one list.

How do I do that?

Answer 1

def get_companies_and_titles(self):
    return self.get_companies() + self.get_title()

This will get you a list with all companies followed by all titles. In case you want (company, title) tuples in your result-list, use:

def get_companies_and_titles(self):
    return zip(self.get_companies(), self.get_title())

The second option can yield unexpected results if the lists are not of the same length. Have a look at the documentation for zip and izip_longest in that case.
