将数据添加到来自网站的列表

Question

我遇到的问题是 list_titles.append（标题）所在的行 在最底部，它提出了错误： TypeError：append（）不带关键字参数。请帮助，谢谢！ 每次循环我想要将项目添加到列表中。

import urllib.request
from bs4 import BeautifulSoup
import time
import sys
import pprint
list_titles = []
list_recipes = []


def user_input():

   keyword = input('Please type in dinner ideas and we will give you recipes:')
   return keyword



def get_html():

    keyword = user_input()

    search_page_url = 'http://www.foodnetwork.com/search/'
    search_page = urllib.request.urlopen(search_page_url+keyword+'-') #downloads 
    the webpage
    search_soup = BeautifulSoup(search_page,'html.parser') #create a tree data 
    structure out of html
    ### find all of the 'h3' tags with the class 'm-Med...' ....................................................
    ### and get the link by finding all the 'a' tags
    recipe_blocks = search_soup.find_all('h3',class_='m-MediaBlock__a-
    Headline')# finds h3 html tags with that class

    for recipe in recipe_blocks:
        recipe_url = recipe.find_all('a')[0].get('href') # get link as text
        print(recipe_url)
        page = urllib.request.urlopen('http:'+recipe_url)
        soup = BeautifulSoup(page,'html.parser')

        for name in soup.find_all('div',class_='parbase assetTitle')
        [0].find_all('span',class_='o-AssetTitle__a-HeadlineText'):

            title = ('  '+name.get_text()
            **list_titles.append(title)**     
            pprint.pprint(list_titles)

        for ingredients in soup.find_all('div',class_='o-Ingredients__m-
        Body')[0].find_all('label',class_='o-Ingredients__a-ListItemText'):

        recipe = ('  '+ingredients.get_text())# gets text from ingredients

        list_recipes.append(recipe) # gets text from ingredients

    pprint.pprint(list_recipes)
