Question

我正在尝试弄清楚如何从具有被称为“发送时间”的列的表中提取数据。并且日期时间介于两个日期时间之间。正如您在代码中看到的那样，格式是＆＃39; YYYY-dd-MM HH：mm：ss＆＃39; 。根据我改变代码的方式，我会一直得到不同的错误。你能告诉我哪里出错了吗？

我想向您提供我所有其他文件的所有信息以及我拍摄的内容，看看您是否可以复制并实际让它工作，看看它是不是只是我的系统或我有一些配置..

我有一个带有一个table的数据库。我们称之为'table1'该表按照以下列分类：

让我们说这些是两个或更多的客户互相送货。每个客户都有三个id＃s。

我创建了一个'config.ini'文件，让我的生活更轻松

[mysql]
host = localhost
database = db_name
user = root
password = blahblah

我创建了'python_mysql_dbconfig.py'

from configparser import ConfigParser

def read_db_config(filename=’config.ini’, section=’mysql’):
“”” Read database configuration file and return a dictionary object
:param filename: name of the configuration file
:param section: section of database configuration
:return: a dictionary of database parameters
“””
# create parser and read ini configuration file
parser = ConfigParser()
parser.read(filename)

# get section, default to mysql
db = {}
if parser.has_section(section):
items = parser.items(section)
for item in items:
db[item[0]] = item[1]
else:
raise Exception(‘{0} not found in the {1} file’.format(section, filename))

return db

现在这是我一直致力于编写的代码，它应该提取两个日期之间的行。但我一直收到这个错误：

   **Traceback (most recent call last):
  File "C:\Python34\timerange.py", line 33, in <module>
    dt_start = datetime.strptime(userIn,timeShape)
TypeError: must be str, not tuple**

你能看看这个并告诉我我做错了吗？

timerange.py

我在输入中使用了dateutil.parser.parse并且能够得到一些结果......我有一个新的错误，但我会将其发布在一个现在的问题上。谢谢你的帮助。
