Installing MySQL connection from Anaconda

Download & install Anaconda with Python by using mysqlclient to connect to MySQL database server

Before this you must have MySQL database running and keep your connection userid and password with your database name ready.

We need to install MySQL connector to connect from Python to MySQL database.

Inside Anaconda goto Environment at your left side navigational menu
MySQL installation from Anaconda

Middle you can see Base root
From Base root select Open Terminal
MySQL installation from Anaconda

You will reach the Anaconda terminal where you can install any package . Just enter this line at the prompt to install MySQL connector.

conda install -c anaconda mysql-connector-python

This will install your MySQL connector by downloading packages from the internet. Now it is time to check the connection.

MySQL connection using SQLAlchemy

Using SQLAlchemy

For updating the database you need to use sqlalchemy and its create_engine
Here is the code to get the connection by using sqlalchemy

from sqlalchemy import create_engine
engine = create_engine("mysql+mysqldb://userid_here:password_here@localhost/db_name")
my_conect = engine.connect()

If you are getting error message like this.
No module named 'MySQLdb'
then you need to install mysqlclient.
Open your Anaconda terminal as explained above and then enter

pip install mysqlclient

To check the installation

pip show mysqlclient

Checking mysqlclient installation for python

SQLAlchemy

pip install sqlalchemy

To check the installation

pip show sqlalchemy
