How can directory containing a CSV file be converted into an Sqlite3 database using Python?

edit

To convert a directory containing a CSV file into an SQLite3 database using Python, you can follow the below steps:

1. Install the required package: First, you need to install the Pandas package, which is used to read the CSV file and convert it into a DataFrame. You can install it using the following command:

pip install pandas

1. Create a SQLite3 database: Create an empty SQLite3 database using the SQLite3 command-line tool or any other SQLite3 management tool.

2. Create a table: Once you have created the database, create a table with the same columns as the CSV file. You can use the following SQL statement to create a table:

CREATE TABLE table_name (
    column1 datatype1,
    column2 datatype2,
    column3 datatype3,
    .....
);

1. Read CSV file: Use the Pandas read_csv method to read the CSV file into a DataFrame object.

import pandas as pd

df = pd.read_csv('file.csv')

1. Write to SQLite3 database: Use the Pandas to_sql method to write the DataFrame to the SQLite3 database.

import sqlite3

conn = sqlite3.connect('database.db')
df.to_sql('table_name', conn, if_exists='replace', index=False)
conn.close()

In the above code, the 'if_exists' parameter is used to replace the table if it already exists in the database. The 'index' parameter is set to False to prevent Pandas from adding an index as a new column in the database.

Using the above steps, you can easily convert a directory containing a CSV file into an SQLite3 database using Python.
