[英]Sending two Pandas dataframes side-by-side using HTML in email
我正嘗試通過電子郵件發送有關我的股票投資組合創建的一些摘要。 我正在使用Python + Pandas進行計算,並使用email.mime模塊通過電子郵件發送html。
我正在使用Pandas的to_html方法和email.mime模塊將html包含在電子郵件中:
import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
import numpy as np
import pandas as pd
import pickle
from utils import mail
def send_fancy_mail(subject, text_message, html_message):
msg = MIMEMultipart('alternative')
msg['Subject'] = subject
msg['From'] = 'mymail@domain.com'
msg['To'] = settings.MAIL_RECIPIENTS
# Record the MIME types of both parts - text/plain and text/html.
part1 = MIMEText(text_message, 'plain')
part2 = MIMEText(html_message, 'html')
msg.attach(part1)
msg.attach(part2)
# Send the message via our own SMTP server.
s = smtplib.SMTP_SSL(settings.SMTP_HOST)
s.login(settings.SMTP_USER, settings.SMTP_PASSWORD)
s.send_message(msg)
s.quit()
fake_or_load = 'fake'
if fake_or_load == 'fake':
n_signals = 20
symbols = np.round(1000*np.random.rand(n_signals)).astype(int)
direction = ["Buy" for i in range(n_signals//2)]
direction.extend(["Sell" for i in range(n_signals//2)])
quantity = np.round(10000*np.random.rand(n_signals)).astype(int)
portfolio = pd.DataFrame({'symbols': symbols, 'direction': direction, 'quantity': quantity})
elif fake_or_load == 'load':
with open('c:\\\\temp\\signals_list', 'rb') as fp:
signals = pickle.load(fp)
portfolio = pd.DataFrame(signals)
portfolio.rename(index=str, inplace=True, columns={0: "symbol", 1: "direction", 2: "quantity"})
shares_to_buy = portfolio[portfolio['direction'] == 'Buy'].copy()
shares_to_buy.sort_values(by='quantity', inplace=True, ascending=False)
shares_to_sell = portfolio[portfolio['direction'] == 'Sell'].copy()
shares_to_sell.sort_values(by='quantity', inplace=True, ascending=False)
# The basic way to convert portfolio to html:
html_to_buy = shares_to_buy.to_html(index=False, header=True, col_space=20, justify='center')
html_to_sell = shares_to_sell.to_html(index=False, header=True, col_space=20, justify='center')
mail_body = "Test Message"
css = """
.div {
flex-direction: row;
}
"""
html_body = """
<html>
<head>
<style>{}</style>
</head>
<body>
<div>{}</div>
<div>{}</div>
</body>
</html>
""".format(css, html_to_buy, html_to_sell)
mail.send_fancy_mail("Test Mail", mail_body, html_body)
我想在電子郵件正文中並排放置兩列,最好也能調節列寬。 是否可以使表響應?
如果要創建兩列,請用下表替換兩個div。 Div的支持與所有電子郵件客戶端上的表不同。
<table style="width:100%"> <tr> <td>column 1</td> <td>column 2</td> </tr> </table>
