Python Tkinter CSV data entry and writer

Python Tkinter File Operations and Integration: Exercise-3 with Solution

Write a Python program that writes data to a CSV file using the Tkinter.

Sample Solution:

Python Code:

import tkinter as tk
import csv

class CSVWriterApp:
    def __init__(self, root):
        self.root = root
        self.root.title("CSV Writer")

        # Create labels and entry fields for data input
        self.label1 = tk.Label(root, text="Student Name:")
        self.entry1 = tk.Entry(root)
        self.label2 = tk.Label(root, text="Class:")
        self.entry2 = tk.Entry(root)
        self.label3 = tk.Label(root, text="Marks:")
        self.entry3 = tk.Entry(root)

        # Create a "Save" button
        self.save_button = tk.Button(root, text="Save", command=self.save_data)

        # Place labels, entry fields, and button on the grid
        self.label1.grid(row=0, column=0)
        self.entry1.grid(row=0, column=1)
        self.label2.grid(row=1, column=0)
        self.entry2.grid(row=1, column=1)
        self.label3.grid(row=2, column=0)
        self.entry3.grid(row=2, column=1)
        self.save_button.grid(row=3, column=0, columnspan=2)

    def save_data(self):
        # Get data from entry fields
        name = self.entry1.get()
        age = self.entry2.get()
        country = self.entry3.get()

        # Open the CSV file for writing
        with open("temp.csv", mode="a", newline="") as csv_file:
            csv_writer = csv.writer(csv_file)

            # Write the data to the CSV file
            csv_writer.writerow([name, age, country])

        # Clear the entry fields
        self.entry1.delete(0, tk.END)
        self.entry2.delete(0, tk.END)
        self.entry3.delete(0, tk.END)

if __name__ == "__main__":
    root = tk.Tk()
    app = CSVWriterApp(root)
    root.mainloop()

Explanation:

In the exercise above -

The program creates a GUI application using Tkinter where you can input data into input fields (Student Name, Class, Marks). When you click the "Save" button, it takes the input values and appends them as a new row to a CSV file named "temp.csv." The file name and path can be modified.

Output:
