Final Project

Python Programming For Beginners

Develop a Small Application Incorporating the Concepts Learned

Objective: Develop a small application that incorporates the concepts learned throughout the course. This project will help reinforce the knowledge and skills acquired.

Examples:

To-Do List Application:

Features: Add, remove, and display tasks.
Concepts: Lists, functions, file I/O, GUI programming.

python

import tkinter as tk

tasks = []

def add_task():
    task = entry.get()
    if task:
        tasks.append(task)
        listbox.insert(tk.END, task)
        entry.delete(0, tk.END)

def remove_task():
    selected_task_index = listbox.curselection()
    if selected_task_index:
        tasks.pop(selected_task_index[0])
        listbox.delete(selected_task_index)

root = tk.Tk()
root.title("To-Do List")

entry = tk.Entry(root)
entry.pack()

add_button = tk.Button(root, text="Add Task", command=add_task)
add_button.pack()

remove_button = tk.Button(root, text="Remove Task", command=remove_task)
remove_button.pack()

listbox = tk.Listbox(root)
listbox.pack()

root.mainloop()

Simple Calculator:

Features: Basic arithmetic operations (addition, subtraction, multiplication, division).
Concepts: Functions, GUI programming.

python

import tkinter as tk

def calculate(operation):
    try:
        result = eval(entry.get())
        entry.delete(0, tk.END)
        entry.insert(tk.END, str(result))
    except Exception as e:
        entry.delete(0, tk.END)
        entry.insert(tk.END, "Error")

root = tk.Tk()
root.title("Simple Calculator")

entry = tk.Entry(root)
entry.pack()

buttons = [
    ('7', 1, 0), ('8', 1, 1), ('9', 1, 2),
    ('4', 2, 0), ('5', 2, 1), ('6', 2, 2),
    ('1', 3, 0), ('2', 3, 1), ('3', 3, 2),
    ('0', 4, 1), ('+', 1, 3), ('-', 2, 3),
    ('*', 3, 3), ('/', 4, 3), ('=', 4, 2),
]

for (text, row, col) in buttons:
    button = tk.Button(root, text=text, command=lambda t=text: entry.insert(tk.END, t) if t != '=' else calculate(entry.get()))
    button.grid(row=row, column=col)

root.mainloop()
