Required Software (Download)

• Python, Download-> https://www.python.org/downloads/
• Pycharm (Community), Download-> https://www.jetbrains.com/pycharm/download/?section=windows
• Or, Visual Studio, Download-> https://code.visualstudio.com/download
• For MySQL Database, Download-> https://www.mysql.com/downloads/

Python Install

Many PCs and Macs will have Python already installed. To check if you have Python installed on a Windows PC, search in the start bar for Python or run the following on the Command Line (cmd.exe):

python --version

The Python Command Line

C:\Users\Your Name>python

Or, if the "python" command did not work, you can try "py"

C:\Users\Your Name>py

From there you can write any Python, including our hello world example from earlier in the tutorial

>>> print("Hello, World!")

Python MySQL (Database)

To be able to experiment with the code examples in this tutorial, you should have MySQL installed on your computer. You can download a MySQL database at https://www.mysql.com/downloads/.

Connect the database as follows

• Install MySQL Driver
• Python needs a MySQL driver to access the MySQL database. In this tutorial, we will use the driver "MySQL Connector".
• We recommend that you use PIP to install "MySQL Connector".
• PIP is most likely already installed in your Python environment.

Navigate your command line to the location of PIP, and type the following-

Download and install "MySQL Connector"

C:\Users\Your Name\AppData\Local\Programs\Python\Python36-32\Scripts>python -m pip install mysql-connector-python

Create Connection

demo_mysql_connection.py

import mysql.connector

mydb = mysql.connector.connect(
  host="localhost",
  user="yourusername",
  password="yourpassword"
)

print(mydb)
