Using Postgres Cloud Database With Tkinter – Python Tkinter GUI Tutorial 187

In this video I’ll show you how to use the Postgres database in the cloud with your Tkinter app!

Connect your tkinter app to a postgres database in the cloud! We’ll use heroku to host our postgresql database and connect to it from our Tkinter app.

Python Code: cloud_db.py
(Github Code)

from tkinter import *
import psycopg2
# postgresql-cubic-98264

root = Tk()
root.title('Codemy.com - Postgres Cloud App')
root.iconbitmap('c:/gui/codemy.ico')
root.geometry("500x550")

	f_name.delete(0, END)
	_name.delete(0, END)

	# Create a cursor
	c = conn.cursor()

	# Create a Table
