Create a lap timer with Python

Situatie

The user needs to press ENTER to complete each lap. The timer keeps counting till CTRL+SHIFT 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.

Backup

# importing libraries

import time

# Timer starts

starttime=time.time()

lasttime=starttime

lapnum=1

print("Press ENTER to count laps.\nPress CTRL+SHIFT 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+SHIFT is pressed

except KeyboardInterrupt:

print("Done")
