Question

我需要读取CSV输入文件并在电子邮件正文中发送CSV内容html表格式。 CSV包含5列，所有5列的数据均为“成功”或“失败”。需要突出显示绿色的“成功”列和红色的“失败”列。我能够发送html表格格式的电子邮件。但是无法基于CSV值进行颜色编码。请执行Needfull。

import smtplib
from smtplib import SMTPException
import csv
from tabulate import tabulate
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
import smtplib





table = ''
with open('alert.csv') as csvFile:
    reader = csv.DictReader(csvFile, delimiter=',')
    table = '<tr>{}</tr>'.format(''.join(['<td class="cell">{}</td>'.format(header) for header in reader.fieldnames]))
    for row in reader:
        table_row = '<tr>'
   #     #print(table)
        for fn in reader.fieldnames:

            table_row += '<td class="cell">{}</td>'.format(row[fn])
            table_row += '</tr>'
            table += table_row



html = """

 td.cell{
    background-color: blue;
 }

</style>

message = MIMEMultipart(
    "alternative", None, [MIMEText(html,'html')])


message['Subject'] = "Some stats via mail"
message['From'] = 'donotreply@xxx.com'
message['To'] = 'pooja.kamat@xxx.com'

sender = "donotreply@xxx.com"
receivers = ['abc.def@xxx.com']

最简单的方法是创建两个类，一个用于成功，一个用于失败，然后简单地将它们分配给单元格。由于已经填充了背景颜色，因此您不清楚“突出显示”的含义是什么，但是您应该能够轻松地进行调整。

在“样式”元素中

/* Place after td.cell */
td.success {
    background-color: green; /* Highlight success as green */
}
td.failure {
    background-color: red; /* Highlight failure as red */
}

施工中

for fn in reader.fieldnames:
    ## row[fn] is expected to equal "success" or "failure"
    ## These are style classes (success=green, failure=red)
    ## If row[fn] is neither, it will be highlighted blue
    table_row += '<td class="{0} cell">{0}</td>'.format(row[fn])

## This should be de-indented (might have been copying error)
table_row += '</tr>'
table += table_row

将csv文件作为html表，并使用Python w
