How to create a pdf file and share through mail

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()
