The 本製品 can be used to create ETL applications and pipelines for CSV data in Python using Petl.

Install Required Modules

Install the Petl modules using the pip utility.

pip install petl

Connecting

After you import the modules, including the CData Python Connector for Email, you can use the 本製品's connect function to create a connection using a valid IMAP connection string. If you prefer not to use a direct connection, you can use a SQLAlchemy engine.

import petl as etl
import cdata.email as mod
cnxn = mod.connect("Port=993;Server=outlook.office365.com;Password=password;User=user;Protocol=IMAP;SMTP Port=587;SMTP Server=smtp.office365.com;")

Extract, Transform, and Load the IMAP Data

Create a SQL query string and store the query results in a DataFrame.

sql = "SELECT	From, Subject FROM [INBOX] "
table1 = etl.fromdb(cnxn,sql)

Loading Data

With the query results stored in a DataFrame, you can load your data into any supported Petl destination. The following example loads the data into a CSV file.

etl.tocsv(table1,'output.csv')

Modifying Data

Insert new rows into IMAP tables using Petl's appenddb function.

table1 = [['From','Subject'],['A Message Subject','Spam']]
etl.appenddb(table1,cnxn,'[INBOX]')
