Today I built a stopwatch application using PyQt5 with a video tutorial. It has a simple interface with a time display and three buttons: Start, Stop, and Reset. The stopwatch updates in real time and keeps track of hours, minutes, seconds, and milliseconds.

class Stopwatch(QWidget):

^This class defines the entire stopwatch application. It sets up the time , UI elements like the label and buttons, and the timer that updates the display.

def initUI(self):

^This function builds the interface. It creates the layout, adds the time display and buttons, centers the text, applies styling, and connects each button to its function.

def start(self):

^This starts the timer. It runs every 10 milliseconds so the stopwatch updates smoothly.

def reset(self):

^This stops the timer, resets the time back to zero, and updates the display to show 00:00:00.00.
