Python-使用CSV附件发送电子邮件

Question

I have a script that creates a CSV file to later use to send in an email. I am running into issues opening the file as read-only to then send as an attachment. Below is my current code.

#Below code creates the CSV file
keys = lstMaster[0].keys()

with open('myfile.csv' , 'w') as outputFile:
    writer = csv.DictWriter(outputFile, keys)
    writer.writeheader()
    writer.writerows(lstMaster)

def createEmail(outputFile)
    msg = MIMEMultipart()
    msg['Subject'] = 'CSV report'
    msg['From'] = "email@domain.com"
    msg['To'] = (["me@domain.com"])
    msg.preamble = 'Attachment' 

    with open(outputFile, newline='') as file:
        attachment = csv.DictReader(file)

    attachment.add_header('Content-Disposition', 'attachment', `enter code here`filename='myfile.csv')
    msg.attach(attachment)

I am not getting any error messages but the code dies when trying to open the CSV file within the createEmail function "with open(outputFile, newline='') as file:" .

Answer 1

It ended up that instead of calling outputFile in the "read" statement, I needed to call the file name itself.

with open(outputFile, newline='') as file:

changed to:

with open('filename', 'r') as file:
