Create a simple time tracker in Python

Here’s a simple time tracker in Python that lets you start, stop, and view the elapsed time for a task. It’s a command-line script with basic functionality:

python
CopyEdit
import time

class TimeTracker:
    def __init__(self):
        self.start_time = None
        self.elapsed = 0

    def start(self):
        if self.start_time is not None:
            print("Timer is already running.")
        else:
            self.start_time = time.time()
            print("Timer started.")

    def stop(self):
        if self.start_time is None:
            print("Timer is not running.")
        else:
            end_time = time.time()
            self.elapsed += end_time - self.start_time
            self.start_time = None
            print(f"Timer stopped. Total time: {self.format_time(self.elapsed)}")

    def reset(self):
        self.start_time = None
        self.elapsed = 0
        print("Timer reset.")

    def status(self):
        if self.start_time is not None:
            current = time.time() - self.start_time + self.elapsed
        else:
            current = self.elapsed
        print(f"Current elapsed time: {self.format_time(current)}")

    def format_time(self, seconds):
        minutes, seconds = divmod(int(seconds), 60)
        hours, minutes = divmod(minutes, 60)
        return f"{hours:02}:{minutes:02}:{seconds:02}"

def main():
    tracker = TimeTracker()
    print("Simple Time Tracker")
    print("Commands: start, stop, reset, status, exit")
    while True:
        command = input("Enter command: ").strip().lower()
        if command == "start":
            tracker.start()
        elif command == "stop":
            tracker.stop()
        elif command == "reset":
            tracker.reset()
        elif command == "status":
            tracker.status()
        elif command == "exit":
            if tracker.start_time is not None:
                tracker.stop()
            print("Exiting Time Tracker.")
            break
        else:
            print("Invalid command.")

if __name__ == "__main__":
    main()

Features:

• start begins tracking time.

• stop halts tracking and adds to total elapsed.

• reset clears all tracking.

• status shows current tracked time.

• exit stops tracking and exits the app.

You can run this script in any terminal or command prompt that supports Python.
