我正在使用Jupyter笔记本,但是当我尝试通过简单地给出变量名并按Shift + Enter而不是在笔记本中(单元格旁边)获取输出来打印某些东西以获取任何输出时,我得到了在我启动笔记本电脑的终端中找到它。我想查看笔记本本身的输出,并最终将数据存储为数据框并导出为csv。
代码:
from multiprocessing import Process, Pool
import datetime
import time
import worker
start = time.time()
if __name__ == '__main__':
pool = []
numdays = 365
start_date = datetime.datetime(2019, 1, 15 ) #year - month - day
datelist = [
(start_date - datetime.timedelta(days=x)).strftime('%Y%m%d') for x in
range(0, numdays)
]
pool = Pool(processes=16)
pool.map(worker.load, datelist)
pool.close()
pool.join()
和工作程序模块
import pandas as pd
import datetime
import urllib
import requests
from pprint import pprint
import time
from io import StringIO
symbols = ['AAP']
start = time.time()
dflist = []
def load(date):
if date is None:
return
url = "http://regsho.finra.org/FNYXshvol{}.txt".format(date)
try:
df = pd.read_csv(url,delimiter='|')
if any(df['Symbol'].isin(symbols)):
stocks = df[df['Symbol'].isin(symbols)]
print(stocks.to_string(index=False, header=False))
# Save stocks to mysql
else:
print(f'No stock found for {date}' )
except urllib.error.HTTPError:
pass
The results in the terminal are as follows
我希望能够简单地将此数据作为数据框。 我怀疑这是由于Jupyter笔记本模块出现问题。
