[英]How to send a Python Dataframe through an E-mail?
我在通过电子邮件发送 DataFrame 时遇到问题。 每当我导出或打印它时,DataFrame 看起来都很好。 然而,通过电子邮件,它看起来一团糟。
当然,我已经尝试过 Pandas 提供的to_html
选项。 还有来自pretty_html_table
包的build_table
。
每当我通过电子邮件发送数据帧时,它都会返回:
Dear mister X,
Please have a look at these numbers. There is a big change in revenue since 11-10-2021 compared to 10-10-2021:
<p><table border="0" class="dataframe">

我认为这可能与我用来发送电子邮件的代码有关。 我想在其中插入不同的变量。 这是电子邮件的代码:
email_df = build_table(df, "blue_light")
subject = f"Subject: blablabla - {today}"
message = f"\n\nDear mister X, \n\n Please have a look at these numbers. There is a big change in revenue since {period 1} compared to {period 2}: \n\n {email_df}"
emailcontent = f'{subject}{message}'
context = ssl.create_default_context()
with smtplib.SMTP_SSL(smtp_server, port, context=context) as server:
server.login(sender_email, password)
server.sendmail(sender_email, receiver_email, emailcontent)
欢迎任何帮助! :)
您当前以纯文本格式发送电子邮件,这使得无法确保列间距正确,除非收件人碰巧在纯文本阅读器中查看他们的电子邮件。
为确保表格的间距正确,您必须发送一封 HTML 电子邮件 - 请参阅此处的示例和此答案。 类似以下(未经测试)的东西应该可以工作:
from email.message import EmailMessage
import smptlib
email = EmailMessage()
email['Subject'] = f"Subject: blablabla - {today}"
email['From'] = sender_email
email['To'] = receiver_email
email.set_content(f"""\
<html><head></head><body>
<p>Dear mister X,</p>
<p>Please have a look at these numbers. There is a big change in revenue since {period 1}
compared to {period 2}:</p>
{df.to_html()} # or use build_table(df) for prettier formatting
</body></html>""", subtype='html')
context = ssl.create_default_context()
with smtplib.SMTP_SSL(smtp_server, port, context=context) as server:
server.login(sender_email, password)
server.send_message(email)
