INSTALLING PYTHON SQLITE3
SQLite3 is a powerful, lightweight database engine that's great for various applications. When using Python, integrating SQLite3 becomes seamless, thanks to its built-in support. Let's dive into the installation process.
First, ensure you have Python installed on your system. You can download the latest version from the official Python website. During the installation, be sure to check the box that says "Add Python to PATH." This step is crucial for easily running Python commands in your terminal or command prompt.
Once Python is installed, you can access SQLite3 without needing any additional installations. Yes, you heard it right! SQLite3 comes as part of the standard library with Python. So, after installing Python, you're almost ready to use SQLite
However, to verify if everything is set up correctly, open a terminal or command prompt and type:
```
python
```
This command launches the Python interpreter. Next, try importing the SQLite3 module:
```python
import sqlite3
```
If you don’t see any error messages, congratulations! You successfully installed Python SQLite
USING SQLITE3 IN PYTHON
Now that SQLite3 is installed, let’s explore how to use it. Start by creating a new SQLite database. You can do this by running the following code:
```python
connection = sqlite
- connect('my_database.db')
This command creates a new database file named `my_database.db`. If the file already exists, it will connect to it.
Next, create a table within the database. Use the following snippet:
```python
cursor = connection.cursor()
cursor.execute('''
CREATE TABLE IF NOT EXISTS users (
id INTEGER PRIMARY KEY,
name TEXT NOT NULL,
age INTEGER
)
''')
connection.commit()
```
This code creates a `users` table with three columns: `id`, `name`, and `age`.
Finally, don't forget to close the connection to your database when you're done:
```python
connection.close()
```
In summary, Python SQLite3 is readily available with your Python installation. Use it to create and manage databases effortlessly. Happy coding!
