How to Visualize Tally Data in Python with pandas

The rich ecosystem of Python modules lets you get to work quickly and integrate your systems more effectively. With the CData Python Connector for Tally, the pandas & Matplotlib modules, and the SQLAlchemy toolkit, you can build Tally-connected Python applications and scripts for visualizing Tally data. This article shows how to use the pandas, SQLAlchemy, and Matplotlib built-in functions to connect to Tally data, execute queries, and visualize the results.

With built-in optimized data processing, the CData Python Connector offers unmatched performance for interacting with live Tally data in Python. When you issue complex SQL queries from Tally, the driver pushes supported SQL operations, like filters and aggregations, directly to Tally and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).

Connecting to Tally Data

Connecting to Tally data looks just like connecting to any relational data source. Create a connection string using the required connection properties. For this article, you will pass the connection string as a parameter to the create_engine function.

Set the following connection properties to connect to Tally Instance:

• Url: Set this to the URL for your Tally instance. For example: http://localhost:9000.

Follow the procedure below to install the required modules and start accessing Tally through Python objects.

Install Required Modules

Use the pip utility to install the pandas & Matplotlib modules and the SQLAlchemy toolkit:

pip install pandas
pip install matplotlib
pip install sqlalchemy

Be sure to import the module with the following:

import pandas
import matplotlib.pyplot as plt
from sqlalchemy import create_engine

Visualize Tally Data in Python

You can now connect with a connection string. Use the create_engine function to create an Engine for working with Tally data.

engine = create_engine("tally:///?Url='http://localhost:9000'")

Execute SQL to Tally

Use the read_sql function from pandas to execute any SQL statement and store the resultset in a DataFrame.

df = pandas.read_sql("SELECT Name, Address FROM Company WHERE CompanyNumber = '1000'", engine)

Visualize Tally Data

With the query results stored in a DataFrame, use the plot function to build a chart to display the Tally data. The show method displays the chart in a new window.

df.plot(kind="bar", x="Name", y="Address")
plt.show()
