Head First Python's Database Context Manager
Project description
The UseDatabase context manager for working with MariaDB and SQLite3.
The 1.x release of this module was based on code created for the second edition of Head First Python. See Chapters 7, 8, 9, and 11 of the that book for information on how this was done. Release 1 targetted the MySQL server.
For the third edition of Head First Python, DBcm moved to release 2 and now targets MariaDB as its primary back-end database (although it should still work with MySQL). The option to use SQLite (v3) is also supported by this release.
Simple example usage (with MariaDB):
from DBcm import UseDatabase, SQLError
config = { 'host': '127.0.0.1',
'user': 'myUserid',
'password': 'myPassword',
'database': 'myDB' }
with UseDatabase(config) as cursor:
try:
_SQL = "select * from log"
cursor.execute(_SQL)
data = cursor.fetchall()
except SQLError as err:
print('Your query caused an issue:', str(err))
If a filename (string) is used in place of the dictionary with UseDataBase, the data is assumed to reside in a local SQLite database file.
Note: It is assumed you have a working version of the MariaDB server running on the computer onto which you're installing DBcm. (If not, you'll get build errors due to the absence of the MariaDB client-side C tools).
