How to make a database in Python

Learn how to create a database in Python using an example. Create and manage databases quickly and easily with this step-by-step guide.

Creating a Database in Python

Python is a great language for creating databases. With its simple syntax, powerful object-oriented programming capabilities, and comprehensive standard library, it is a popular choice for developers who want to create robust databases quickly and efficiently. Here is an example of how to create a database in Python.

The first step is to import the library that will be used to create the database. For this example, we will use the SQLite3 library, which is part of the standard Python library. All that is needed is to add the following line of code to the top of your Python file:

import sqlite3

The next step is to create a connection to the database. This is done by instantiating a connection object, which can be done with the following line of code:

conn = sqlite3.connect('my_database.db')

Now that the connection is established, a cursor can be created to execute SQL commands. This is done by calling the cursor() method on the connection object, like this:

cursor = conn.cursor()

Now that the cursor is created, SQL commands can be executed. For example, to create a new table named “users” with three columns, the following command can be used:

cursor.execute("CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT, email TEXT)")

Once the table has been created, data can be inserted into it using an INSERT command. For example, to insert a new user with the name “John Doe” and the email “[email protected]”, the following command can be used:

cursor.execute("INSERT INTO users (name, email) VALUES ('John Doe', '[email protected]')")

Finally, the changes must be committed to the database. This is done by calling the commit() method on the connection object, like this:

conn.commit()

And with that, the database is created and data has been inserted. This is just a simple example of how to create a database in Python; for more information, please refer to the official Python documentation.
