Python Program to Create a Lap Timer
When it is required to create a lap timer using Python, the ‘time’ method is used. The number of laps is predefined, and a try catch block is defined, to start the lap timer.
Below is a demonstration of the same −
Example
import time
start_time=time.time()
end_time=start_time
lap_num=1
print("Click on ENTER to count laps.\nPress CTRL+C to stop")
try:
while True:
input()
time_laps=round((time.time() - end_time), 2)
tot_time=round((time.time() - start_time), 2)
print("Lap No. "+str(lap_num))
print("Total Time: "+str(tot_time))
print("Lap Time: "+str(time_laps))
print("*"*20)
end_time=time.time()
lap_num+=1
except KeyboardInterrupt:
print("Exit!")Output
Click on ENTER to count laps. Press CTRL+C to stop Lap No. 1 To tal Time: 1.77 Lap Time: 1.77 ******************** Lap No. 2 Total Time: 3.52 Lap Time: 1.75 ******************** Exit!
Explanation
The required packages are imported.
The start time, end time and number of laps are defined.
The timer starts by clicking on ‘Enter’.
In the try catch block, the difference between current time and end time is determined.
Again, the difference between current time and start time is determined.
This gives the number of laps, total time, and lap time.
This is displayed as output on the console.
In the ‘except’ block, the ‘Exit’ is defined.
