我错过了什么,如何让这个功能起作用？

import dateutil.parser
import datetime

my_date = datetime.datetime(2000, 1, 1, 0, 0, 0, 000000, tzinfo=tzutc())

print(my_date)

给我错误:

NameError: name 'tzutc' is not defined

我需要一种有效的方法来编写包含字典（包括日期时间）的文件，然后能够将它们作为字典读取。像这样的字典：

my_dict = {'1.0': [datetime.datetime(2000, 1, 1, 0, 0, 0, 000000, tzinfo=tzutc())], '2.0': [datetime.datetime(2000, 1, 1, 0, 0, 0, 000000, tzinfo=tzutc())]}

尝试使用 json 转储：

with open("my_file.json", 'w+') as f:
    json.dump(my_dict, f)

TypeError: Object of type 'datetime' is not JSON serializable

还尝试将整个 dict 写为一个字符串，然后用 yaml 导入它，这几乎有效，但索引混乱。

with open("my_file", 'w+') as f:
    f.write(str(my_dict))

with open("my_file", 'r') as f:
    s = f.read()
    new_dict = yaml.load(s)

print(new_dict['1.0'][0])

Output:   datetime.datetime(2000
Expected: 2000-01-01 00:00:00+00:00

我正在使用 python 2.7 和 boto3。我想不出一种在 python 中向 SES 添加附件的方法。我找到的最接近的是这个页面。

到目前为止，我所拥有的是：

from email.mime.text import MIMEText
from email.mime.application import MIMEApplication
from email.mime.multipart import MIMEMultipart
import boto3

# via http://codeadict.wordpress.com/2010/02/11/send-e-mails-with-attachment-in-python/
ses = boto3.client('ses')
msg = MIMEMultipart()
msg['Subject'] = 'weekly report'
msg['From'] = email
msg['To'] = other_email

# what a recipient sees if they don't use an email reader
msg.preamble = 'Multipart message.\n'

# the message body
part = MIMEText('Howdy -- here is the data from last week.')
msg.attach(part)

# the attachment …
