This Python code implements a Pomodoro Timer using the Tkinter library. The Pomodoro Technique is a time management method that uses a timer to break work into intervals, traditionally 25 minutes in length, separated by short breaks.
-
The code creates a graphical user interface (GUI) window using Tkinter.
-
It defines constants for colors, font, and time intervals.
-
The
clock_reset()function cancels the current timer and resets the UI elements to their initial state. -
The
start_button_clicked()function is called when the "Start" button is clicked. It calculates the duration of the current interval (work time, short break, or long break) and calls thecount_down()function. -
The
count_down()function handles the countdown mechanism. It updates the timer display and starts a recursive call to itself usingwindow.after()until the countdown reaches zero. When the countdown ends, it callsstart_button_clicked()again and updates the checkmark labels. -
The GUI layout consists of a canvas to display the timer, buttons for starting and resetting, and labels for the timer status and checkmarks.
To use this code, follow these steps:
-
Make sure you have Python installed on your system.
-
Import the necessary modules (
tkinterandmath). -
Copy the provided code into a Python file (e.g.,
pomodoro_timer.py). -
Save an image file named "tomato.png" in the same directory as the Python file. This image will be displayed in the GUI.
-
Open a terminal or command prompt and navigate to the directory where the Python file is saved.
-
Run the Python file using the command:
python pomodoro_timer.py. -
The Pomodoro Timer GUI window will open.
-
Click the "Start" button to start the timer.
-
Click the "Reset" button to reset the timer.
-
The timer will cycle between work time, short breaks, and long breaks according to the Pomodoro Technique.
