[英]Python - Passing a list from one function to another
Trying to pass a list from one function to another (teamurls), which then in turn I will use in another program. 尝试将列表从一个函数传递到另一个函数(teamurls),然后依次在另一个程序中使用。 I have my program working where I have a value output using yield.
我的程序在使用yield产生值的地方工作。 (yield full_team_urls) How do I pass the list from the first function into the second (the def - team_urls) Also is that still possible to return the list and continue using yield aswell?
(yield full_team_urls)如何将列表从第一个函数传递到第二个函数(def-team_urls)还可以返回列表并继续使用yield吗? Can each function only return or output one object?
每个函数只能返回或输出一个对象吗?
Edit: Tried to pass teamurls into the second function as shown below and I get the error - TypeError: team_urls() missing 1 required positional argument: 'teamurls'> 编辑:尝试将teamurls传递到第二个函数,如下所示,但出现错误-TypeError:team_urls()缺少1个必需的位置参数:'teamurls'>
def table():
url = 'https://www.skysports.com/premier-league-table'
base_url = 'https://www.skysports.com'
today = str(date.today())
premier_r = requests.get(url)
print(premier_r.status_code)
premier_soup = BeautifulSoup(premier_r.text, 'html.parser')
headers = "Position, Team, Pl, W, D, L, F, A, GD, Pts\n"
premier_soup_tr = premier_soup.find_all('tr', {'class': 'standing-table__row'})
premier_soup_th = premier_soup.find_all('thead')
f = open('premier_league_table.csv', 'w')
f.write("Table as of {}\n".format (today))
f.write(headers)
premier_soup_tr = premier_soup.find_all('tr', {'class': 'standing-table__row'})
result = [[r.text.strip() for r in td.find_all('td', {'class': 'standing-table__cell'})][:-1] for td in premier_soup_tr[1:]]
teamurls = ([a.find("a",href=True)["href"] for a in premier_soup_tr[1:]])
return teamurls
for item in result:
f.write(",".join(item))
f.write("\n")
f.close()
print('\n Premier league teams full urls:\n')
for item in teamurls:
entire_team = []
# full_team_urls.append(base_url+ item)
full_team_urls = (base_url + item + '-squad')
yield full_team_urls
table()
def team_urls(teamurls):
teams = [i.strip('/') for i in teamurls]
print (teams)
team_urls()
To pass a value into a method, use arguments: 要将值传递给方法,请使用参数:
team_urls(teamurls)
You'll need to specify that argument at the definition of team_urls
as such: 您需要在
team_urls
的定义中指定该参数,如下所示:
def team_urls(teamurls):
