I am planning to use Liquibase(https://www.liquibase.org) to manage the migrations/versioning of Oracle database schemas. The project is in Python using setuptools.
I have seen also Python wrappers for Liquibase but they don't seem to be well maintained.
Does anyone has experience in the integration of Liquibase in python projects? Or a similar?
Are you using SQLAlchemy ? Because there is a tool to manage database migration : Alembic
Alambic is wrapped in another Python Framwework too, like Flask in specific module as Flask-migration.
Try using pyliquibase. you can perform liquibase actions through python script

so I was just wondering. I am designing this Kivy app but I currently use .txt files which is messy and just seems like a huge waste of time. I was wondering if there was a package that could read/write/create MySQL databases with python. However, I do use Pycharm and I read a while back that the free version the one I use. May have some limitations with this.
You could use the mysql package for this.
https://dev.mysql.com/doc/connector-python/en/connector-python-example-connecting.html
The PyCharm support for MySQL is just for viewing the data in the database as a programmer or for debugging.
How can I use Tarantool in conjunction with Django and MySQL for caching (instead of i.e. Redis) and/or in the sense that all read transaction go to Tarantool (after insured MySQL replication) and all writes go into MySQL (preferred option) Would anyone have a sample?
Well. Tarantool does not have a Django plugin. That means you have to introduce it first. By the way, tarantool has python 2.71 and python 3.x1 libraries, so it may be useful for integration.
How it could be implemented? You have to use taranool's python library and also MySQL's python library for creating some Django / Python plugin.
Also. About MySQL replication. Tarantool has this feature, you can get codes from GH repo[2].
I'm not sure that Django's sample could be found.
Afterword. It's the pretty big task :)

UPD: February 2021:
The Django-Tarantool Database Backend was introduced as django-tarantool PyPi package and can be used for Django 1.10-3.1 versions.
pip install django-tarantool
Feel free to contribute to the package https://github.com/artembo/django-tarantool
I have a Monet database to which I need to make a query remotely. There's a plugin for python which would make easier to make the query, but I'm creating a grails application.
So I need to create a Python module to make the query, and somehow integrate it to grails.
Does somebody knows how to do this? Thanks.
You don't do that.
Grails is written in Groovy, which is a JVM language; which means it can run any Java code. Monet provides JDBC drivers which should work with no problems.
You can implement python to java with http://www.jython.org
Jython is an implementation of the Python language for the Java platform
I have a project implemented with Django, I wish to use a tool to help me deploy the project onto the server automatically. I know the fabric library can do it, but I want to know whether or not there are other tools that have similar capabilities.
You can check the entire list here.

Fabric is too easy.

I have a website on an Australian webhost. I have designed my website to allow people to login & their login details are stored in an SQLite3 database. I interact with the SQLite3 database using pythons SQLite3 module(found only in python2.5 & up)
My Problem: the webhost runs Python 2.4 so I cannot communicate with(query or modify) my SQLite3 database. The webhost will not allow me to install my own version of python or upload modules unless I upgrade to VPS.
What do you think are my options to still be able to work/interface with my SQL database? Do you know of way to interact with a SQL database using python modules from Python 2.4 or earlier?
Do you know of a python 2.4 module that will let me interact with an SQL database(can be MySQL, SQLite, etc.)?
There is a Python MySQL Module, called MySQLDB, which supports Python 2.3-2.7: http://sourceforge.net/projects/mysql-python/
The User Guide can be found here: http://mysql-python.sourceforge.net/MySQLdb.html
Check out pysqlite. It is the same module as in the newer python versions and I have used it no prob in 2.4 before.
