Question

我试图在电子邮件中发送html表格。我不确定这是不是最好的方法，但现在我读了CSV，创建了一个表格，然后通过电子邮件发送信息。

这是我到目前为止所做的：

def create_table():
    print("<html><table>")
    # column headers
    print("<th>")
    print("<td>Tech</td>")
    print("<td>Total</td>")
    print("<td>Average</td>")
    print("</th>")

    infile = open("test.csv","r")

    for line in infile:
        row = line.split(",")
        tech = row[0]
        total = row[1]
        average = row[2]
        print("<td>%s</td>" % tech)
        print("<td>%s</td>" % total)
        print("<td>%s</td>" % average)

    print("</table></html>")

SERVER = "localhost"
FROM = "forsdani@amazon.com"
TO = ["forsdani@amazon.com"] # must be a list
SUBJECT = "this is my email"
TEXT = "TABLE GOES HERE?"

message = """\

From: %s
To: %s
Subject: %s

%s

""" % (FROM, ", ".join(TO), SUBJECT, TEXT)

# Send the mail
server = smtplib.SMTP(SERVER)
server.sendmail(FROM, TO, message)
server.quit()

如果我做的话

TEXT = create_table()

然后我得到＆＃34;无＆＃34;对于电子邮件中的文本。我不确定如何纠正从函数到电子邮件正文的数据。

Answer 1

您的函数不会返回任何值，只会打印它们。而不是像：

def create_table():
    print("Hello, World!")
output = create_table() # output is None

尝试：

def create_table():
    string_to_return = "Hello, World!"
    return string_to_return
output = create_table() # output is "Hello, World!"

这里的函数已更改为返回值：

def create_table():
    message = ""
    message += "<html><table>" + "\n"
    # column headers
    message += "<th>" + "\n"
    message += "<td>Tech</td>" + "\n"
    message += "<td>Total</td>" + "\n"
    message += "<td>Average</td>" + "\n"
    message += "</th>" + "\n"

    infile = open("test.csv","r")

    for line in infile:
        row = line.split(",")
        tech = row[0]
        total = row[1]
        average = row[2]
        message += ("<td>%s</td>" % tech) + "\n"
        message += ("<td>%s</td>" % total) + "\n"
        message += ("<td>%s</td>" % average) + "\n"

    message += ("</table></html>") + "\n"
    return message
