There can be two types of Tree view widgets in Tkinter: A Tree view widget is the interaction of the user to browse with the represented hierarchical representation.A Tree view, also known as an 'Outline view,' is the graphical visualization of a hierarchical representation of data with every item having more sub-items.Let us now break the words down we'll learn about each of them one after the other: This tutorial explains the following contents: Using Tkinter, we can display information in hierarchical representation using Treeview.

Once the connection object my_conn is created then the code remain same in case of SQLAlchemy. We used variable i as index for each row and variable j as each column of data. In this variable student is a tuple and it contains one row of data. We will use one tkinter entry component to display each data in the window. This will print 10 rows of records from student table.

So we used another for loop to display each element of this tuple. Each row of data ( here student ) is a tuple. We will use one for loop to collect each row of record from the data set. We used the returned record set i.e r_set as an iterator. This result set contains all our (10) records. Note that SQLite database executes the query part only and return us one result set. You can change this figure to get different number of records from the database. We will use Query with LIMIT to collect 10 records from the student table.īy using LIMIT Query we are restricting our number of records by getting 10 records only from SQLite database. We will use my_conn in our further script as the connection object to get our records.ĭownload or Create my_db.db SQLite Database » The commented line is used when we keep SQLite database in Google Drive.

In windows system, the absolute path is used in above code. #my_conn=create_engine('sqlite:////content/drive/MyDrive/db/my_db.db') My_conn = nnect('my_db.db') using SQLAlchemy connection from sqlalchemy import create_engine We connected to sqlite database and create our student table with sample data.
