打印分配时出现问题

Question

我得到了一个代码，在解决了其中的缩进问题后，它运行时没有错误，但现在我无法将代码打印到列表中。

from bs4 import BeautifulSoup as soup
from urllib.request import urlopen as uReq
import requests
symbol = 'AAPL'
url = "https://www.sec.gov/cgi-bin/browse-edgar?action=getcompany&CIK=" + symbol + "&type=&dateb=&owner=exclude&start=0&count=100&output=atom"
uClient = uReq(url)
page_html = uClient.read()
uClient.close()
html = soup(page_html, 'html.parser')
entries = html.findAll("entry")
shouldContinue = True
link = ""
for entry in entries:
if shouldContinue and (
entry.find("category")["term"].lower() == "10-k" or entry.find("category")["term"].lower() == "10-q" or
entry.find("category")["term"].lower() == "20-f"):

firstUrl = entry.find("link")["href"]
uClientFirstUrl = uReq(firstUrl)
page_html_firstUrl = uClientFirstUrl.read()
uClientFirstUrl.close()
htmlFirstUrl = soup(page_html_firstUrl, 'html.parser')
tds = htmlFirstUrl.findAll("table")[1].findAll("td")
foundtd = False
for td in tds:
if foundtd == True:
link = "https://www.sec.gov" + td.find("a")["href"]
foundtd = False
if "xbrl instance" in td.text.lower():
foundtd = True
shouldContinue = False

def getCash(url, symbol):
uClient = uReq(url)
page_html = uClient.read()
uClient.close()
xml = soup(page_html, 'xml')
cash = xml.findAll("us-gaap:CashAndCashEquivalentsAtCarryingValue")
if len(cash) == 0:
cash = xml.findAll("ifrs-full:Cash")
if len(cash) == 0:
cash = xml.findAll("us-gaap:CashCashEquivalentsRestrictedCashAndRestrictedCashEquivalents")
if len(cash) == 0:
cash = xml.findAll("us-gaap:Cash")
return cash
print(getCash)
getCash(url, symbol)

我尝试过打印作业，也尝试过调用方法，但都没有成功。方向感将不胜感激。非常感谢。

正如我在上面的评论中所提到的：

你期望print(getCash)有什么效果？如果您希望它打印getCash()函数的返回，请删除它(它没有执行任何操作(，并将getCash(url, symbol)调用封装在print()函数中。

基本上，这样做：

print(getCash(url, symbol))
