Question

Write code that connects to a database locally using Python 3

assuming that the database name is "MyDatabase.sql".

Answer 1

To connect to a SQLite local database in Python, you can use the sqlite3 module, ensuring to handle exceptions and close the connection appropriately.

Step-by-step explanation:

Connecting to a Local SQL Database in Python

To connect to a local SQL database in Python, you'd typically use a library such as sqlite3 for SQLite databases or PyMySQL for MySQL databases, depending on the type of your database. In this case, since the file has a '.sql' extension, it seems like we are referring to a SQLite database file. Please note that '.sql' files typically contain SQL commands and cannot be directly used as a database, but for the purpose of this example, we will assume that 'MyDatabase.sql' is indeed a SQLite database file.

Here's a basic example of how to connect to a SQLite database using sqlite3:

import sqlite3

try:
# Establish a connection to the database
connection = sqlite3.connect('MyDatabase.sql')
print("Connected to the database successfully")

# Do database operations using connection cursor
# ...

except sqlite3.Error as e:
print("Error while connecting to database: ", e)
finally:
# Close the connection
if connection:
connection.close()
print("Connection to the database is closed")

Ensure that you handle exceptions to catch any errors that might occur during the connection process. Replace 'MyDatabase.sql' with the correct path to your database file if it is not in your current working directory.
