Python Program to Create a Lap Timer Last Updated : 28 Aug, 2023 Comments Improve Suggest changes Like Article Like Report In this article, we will make a simple timer to calculate lap-time intervals using Python. time: This module provides various time-related functions. It is a part of Python's standard library and does not require installation. Approach: The user needs to press ENTER to complete each lap. The timer keeps counting till CTRL+C is pressed. For each lap we calculate the lap time by subtracting the current time from the total time at the end of the previous lap. The time() function of the time module, returns the current epoch time in milliseconds. Below is the implementation: Python3 # importing libraries import time # Timer starts starttime = time.time() lasttime = starttime lapnum = 1 print("Press ENTER to count laps.\nPress CTRL+C to stop") try: while True: # Input for the ENTER key press input() # The current lap-time laptime = round((time.time() - lasttime), 2) # Total time elapsed # since the timer started totaltime = round((time.time() - starttime), 2) # Printing the lap number, # lap-time and total time print("Lap No. "+str(lapnum)) print("Total Time: "+str(totaltime)) print("Lap Time: "+str(laptime)) print("*"*20) # Updating the previous total time # and lap number lasttime = time.time() lapnum += 1 # Stopping when CTRL+C is pressed except KeyboardInterrupt: print("Done") Output: ENTER to count laps.Press CTRL+C to stopLap No. 1Total Time: 1.09Lap Time: 1.09********************Lap No. 2Total Time: 2.66Lap Time: 1.41********************Lap No. 3Total Time: 5.06Lap Time: 2.23********************Lap No. 4Total Time: 5.63Lap Time: 0.4********************DoneTime complexity: O(1) - the program runs in constant time, regardless of the size of the input.
