【发布时间】：2018-02-25 13:13:37
【问题描述】：

我有一个 csv 文件，我需要将其作为数据帧发送到电子邮件正文中。

但是在我的电子邮件的输出中，我看不到 csv 文件的列，而是将 csv 文件的第一行作为列。

** 这是我的代码：**

import pandas as pd
import csv
from tabulate import tabulate
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
import smtplib

me = 'myemailaddress@gmail.com'
password = 'password'
server = 'smtp.gmail.com:587'
you = 'myemailaddress@gmail.com'

text = """
Hello, Friend.

Here is your data:

{table}

Regards,

Me"""

html = """
<html>
<head>
<style> 
  table, th, td {{ border: 1px solid black; border-collapse: collapse; }}
  th, td {{ padding: 5px; }}
</style>
</head>
<body><p>Hello, Friend This data is from a data frame.</p>
<p>Here is your data:</p>
{table}
<p>Regards,</p>
<p>Me</p>
</body></html>
"""

# with open('input.csv') as input_file:
#     reader = csv.reader(input_file)
#     data = list(reader)

data = pd.read_csv("MySampleFile.csv")
text = text.format(table=tabulate(data, headers="firstrow", tablefmt="grid"))
html = html.format(table=tabulate(data, headers="firstrow", tablefmt="html"))

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

message['Subject'] = "First Attempt"
message['From'] = me
message['To'] = you
server = smtplib.SMTP(server)
server.ehlo()
server.starttls()
server.login(me, password)
server.sendmail(me, you, message.as_string())
server.quit()

【问题讨论】：

请张贴您的 csv 文件的快照

标签： python pandas dataframe

【解决方案1】：

看来我所要做的就是将我的 csv 文件中的各个列提取到一个单独的列表中，该列表可以传递到制表方法的 headers 参数中。

这里是完整的解决方案

import pandas as pd
import csv
from tabulate import tabulate
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
import smtplib

me = 'myemailaddress@gmail.com'
password = 'password'
server = 'smtp.gmail.com:587'
you = 'myemailaddress@gmail.com'

text = """
Hello, Friend.

Here is your data:

{table}

Regards,

Me"""

html = """
<html>
<head>
<style> 
 table, th, td {{ border: 1px solid black; border-collapse: collapse; }}
  th, td {{ padding: 5px; }}
</style>
</head>
<body><p>Hello, Friend This data is from a data frame.</p>
<p>Here is your data:</p>
{table}
<p>Regards,</p>
<p>Me</p>
</body></html>
"""

# with open('input.csv') as input_file:
#     reader = csv.reader(input_file)
#     data = list(reader)

df = pd.read_csv("MySampleFile.csv")
col_list = list(df.columns.values)
data = df
# above line took every col inside csv as list
text = text.format(table=tabulate(data, headers=col_list, tablefmt="grid"))
html = html.format(table=tabulate(data, headers=col_list, tablefmt="html"))

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

message['Subject'] = "First Attempt"
message['From'] = me
message['To'] = you
server = smtplib.SMTP(server)
server.ehlo()
server.starttls()
server.login(me, password)
server.sendmail(me, you, message.as_string())
server.quit()
