No such file or directory: 'download.jpg'-CodePudding

I made a email sender a few months ago and now I have another project and I wanted to re-test this and for some reason it cannot find the JPG image which is basically in the same directory as the python file..

    email_send = 'emailsend'  # Receiver Email (hidden for reason)
    PORT_EMAIL = 'smtp.gmail.com' 
    PORT = 587  # Email Port
    subject = 'email test'

    emailtest = "Test"
    msg = MIMEMultipart()
    msg['From'] = email_user
    msg['To'] = email_send  
    msg['Subject'] = subject  

    body = emailtest
    msg.attach(MIMEText(body, 'plain'))
    filename = 'download.jpg' 
    Email_attachment = open(filename, 'rb')

    part = MIMEBase('application', 'octet-stream')
    part.set_payload((Email_attachment).read()) 
    encoders.encode_base64(part)
    # adds email header with attachment
    part.add_header('Content-Disposition', "attachment; filename= " filename)

    msg.attach(part)  # attaches email
    text = msg.as_string()
    srv = smtplib.SMTP(PORT_EMAIL, PORT)
    srv.starttls()  # runs the email SMTP
    srv.login(email_user, email_password) 
    srv.quit()  # stops

EmailSender()

CodePudding user response：

Relative paths (folders) in respect to project has changed. To be fool-proof, change path to jpg with absolute path derived from where the EmailSend.py is located

import os

currentDir= os.path.abspath(os.path.dirname(__file__))  # gets the current pytho file, SendEmail.py and returns absolute path (parent directory)
filepath=os.path.join(currentDir,"download.jpg")

CodePudding user response：

As a follow-up to @jozefow's answer,

import pathlib

cwd = pathlib.Path.cwd()
filepath = cwd / "download.jpeg"

The difference between their answer and mine is that mine does not assume that the current working directory is the same as the file directory. Assumptions either way can be problematic.

The other key difference is mine is nominally more modern python.
