我目前有一个将从条目列表中获取数据的函数。我有一个DataFrame，它将重复数据。我的代码是
import pandas as pd
import numpy as np
import csv
from requests import get
from bs4 import BeautifulSoup
def earnings(ticker):
url_test = ('https://finance.yahoo.com/calendar/earnings?from=2018-04-08&to=2018-04-14&day=2018-04-12&symbol={}')
for i in l:
url = url_test.format(i)
response = get(url)
soup = BeautifulSoup(response.text, 'html.parser')
table = soup.find('table',{'class':'W(100%)'})
for tr in table:
tr.find('tr')
for td in tr:
td.find('td')
if len(td.contents) >= 3:
tic = td.contents[0].text
tic_list.append(tic)
tic_df = pd.DataFrame(tic_list)
dates = td.contents[2].text
dates_list.append(dates)
dates_df = pd.DataFrame(dates_list)
earnings_df = pd.concat( [dates_df, tic_df], axis=1)
return(earnings_df)
l = {"AAPL", "KO"}
for ticker in l:
earnings_df = earnings(ticker)
earnings_df.to_csv('earnings_df.csv')
When looking at my csv file I will get the same data twice in the form of it repeating under itself. I feel like I messed up somewhere when creating the earnings_df. Any ideas?
