Step 1: Import Necessary Modules
```python
import tkinter as tk
from tkinter import messagebox
import sqlite3
```
In this initial step, we begin by importing essential Python modules.
- Tkinter: This versatile library empowers us to create cross-platform graphical user interfaces.
- Messagebox: The messagebox module allows us to display informative pop-up dialogs to communicate with the user.
- SQLite3: This built-in Python library provides us with the tools necessary to interact with SQLite databases, offering simplicity and reliability for local data storage.
Step 2: Create a SQLite Database and Table
```python
# Connect to the database (or create it if it doesn't exist)
conn = sqlite3.connect('flight_info.db')
# Create a cursor object to execute SQL commands
cursor = conn.cursor()
# Create a table to store flight information
cursor.execute('''
CREATE TABLE IF NOT EXISTS flights (
id INTEGER PRIMARY KEY AUTOINCREMENT,
flight_number TEXT NOT NULL,
origin TEXT NOT NULL,
destination TEXT NOT NULL,
departure_time TEXT NOT NULL,
arrival_time TEXT NOT NULL
)
''')
# Commit the changes and close the connection
conn.commit()
conn.close()
```
Our second step involves setting up the database structure that will securely store all flight-related information. We guide you through the process of connecting to an SQLite database (or creating one if it doesn't exist) and defining a structured table to ensure data integrity.
Step 3: Create the Tkinter GUI
```python
# Create the main application window
root = tk.Tk()
root.title("Flight Information System")
# Create labels and entry fields for input
flight_number_label = tk.Label(root, text="Flight Number:")
flight_number_label.pack()
flight_number_entry = tk.Entry(root)
flight_number_entry.pack()
origin_label = tk.Label(root, text="Origin:")
origin_label.pack()
origin_entry = tk.Entry(root)
origin_entry.pack()
destination_label = tk.Label(root, text="Destination:")
destination_label.pack()
destination_entry = tk.Entry(root)
destination_entry.pack()
departure_time_label = tk.Label(root, text="Departure Time:")
departure_time_label.pack()
departure_time_entry = tk.Entry(root)
departure_time_entry.pack()
arrival_time_label = tk.Label(root, text="Arrival Time:")
arrival_time_label.pack()
arrival_time_entry = tk.Entry(root)
arrival_time_entry.pack()
```
With the database ready, we dive into the heart of our application by creating a user-friendly interface using Tkinter. Labels and input fields are designed to facilitate effortless data entry, ensuring an intuitive experience for users.
Step 4: Define Functions for Database Operations
```python
# Function to insert flight information into the database
def insert_flight():
flight_number = flight_number_entry.get()
origin = origin_entry.get()
destination = destination_entry.get()
departure_time = departure_time_entry.get()
arrival_time = arrival_time_entry.get()
# Connect to the database
conn = sqlite3.connect('flight_info.db')
cursor = conn.cursor()
# Insert data into the table
cursor.execute('''
INSERT INTO flights (flight_number, origin, destination, departure_time, arrival_time)
VALUES (?, ?, ?, ?, ?)
''', (flight_number, origin, destination, departure_time, arrival_time))
# Commit the changes and close the connection
conn.commit()
conn.close()
# Clear the input fields
flight_number_entry.delete(0, tk.END)
origin_entry.delete(0, tk.END)
destination_entry.delete(0, tk.END)
departure_time_entry.delete(0, tk.END)
arrival_time_entry.delete(0, tk.END)
messagebox.showinfo("Flight Information", "Flight information added successfully!")
# Function to retrieve and display flight information
def show_flights():
# Connect to the database
conn = sqlite3.connect('flight_info.db')
cursor = conn.cursor()
# Retrieve flight information from the database
cursor.execute('SELECT * FROM flights')
flight_data = cursor.fetchall()
# Close the connection
conn.close()
# Display flight information in a new window
flight_window = tk.Toplevel(root)
flight_window.title("Flight Information")
for row in flight_data:
flight_info_label = tk.Label(flight_window, text=f"Flight Number: {row[1]}\nOrigin: {row[2]}\nDestination: {row[3]}\nDeparture Time: {row[4]}\nArrival Time: {row[5]}\n")
flight_info_label.pack()
```
This step defines two crucial functions.
- `insert_flight`: This function captures user input for flight details and inserts it into the database, ensuring data accuracy and integrity. It also clears the input fields after insertion and displays a confirmation message to the user.
- `show_flights`: This function retrieves stored flight data from the database and prepares it for display in a user-friendly format. It creates a new window to present the flight information, enhancing the user experience.
Step 5: Create Buttons for Actions
```python
# Create buttons for inserting and displaying flight information
insert_button = tk.Button(root, text="Insert Flight", command=insert_flight)
insert_button.pack()
show_button = tk.Button(root, text="Show Flights", command=show_flights)
show_button.pack()
```
To further enhance user interaction, we add action buttons in our fifth step. The "Insert Flight" button allows users to input new flight data, while the "Show Flights" button displays stored flight information. These buttons serve as convenient interaction points, enhancing the user experience.
Step 6: Start the Tkinter Main Loop
```python
root.mainloop()
```
In the final step, we initiate the Tkinter main loop to keep our application responsive and interactive. This loop handles user input, events, and updates, ensuring a seamless experience for users as they interact with our Flight Information Manager.
