How to create a pdf file and share through mail

Using Streamlit
1

Hello everyone!! I’m trying to create an app that saves all the responses in PDF and sends them via email. This is the end part of the code.

pdf_buffer = BytesIO()
plt.savefig(pdf_buffer, format='pdf')
pdf_buffer.seek(0)

# ReportLab
with open('output.pdf', 'wb') as f:
    pdf_writer = canvas.Canvas(f)
    pdf_writer.showPage()
    pdf_writer.save()

# Send the PDF via email with yagmail
yag = yagmail.SMTP('mail@gmail.com', 'password', timeout = 120, host = 'smtp.gmail.com', port=587)

subject = "Report da Streamlit"

# Enclose the PDF
yag.send(
    to='mail@gmail.com',
    subject=subject,
    attachments=['output.pdf']
)

# Close SMTP connection
yag.close()

But the error is: TimeoutError: [WinError 10060] Unable to establish the connection. Incorrect response from the connected party after the timeout or no response from the connected host

Thanks to all !!

Hi @francescobiondo24

You might find this article from Real Python help as there’s an example code snippet and explanation on how to do this in Python:

You can then make minor adjustments and embed it in your Streamlit app.

Hope this helps!

hello @francescobiondo24 try this

import yagmail
from io import BytesIO
from reportlab.pdfgen import canvas
import matplotlib.pyplot as plt

# ... Your plotting code ...

# Save the plot to a PDF buffer
pdf_buffer = BytesIO()
plt.savefig(pdf_buffer, format='pdf')
pdf_buffer.seek(0)

# ReportLab
with open('output.pdf', 'wb') as f:
    pdf_buffer.seek(0)
    f.write(pdf_buffer.read())

# Send the PDF via email with yagmail
yag = yagmail.SMTP('mail@gmail.com', 'password', host='smtp.gmail.com', port=587, smtp_starttls=True, smtp_ssl=False)

subject = "Report da Streamlit"

# Enclose the PDF
yag.send(
    to='recipient@gmail.com',
    subject=subject,
    contents="Report attached.",
    attachments=['output.pdf']
)

# Close SMTP connection
yag.close()
