Output elapsed time for data logging (for yourself)

Stopwatch

This is a memo for myself.

It's like a stopwatch for logging data such as temperature. Normally, the time is recorded, but this time it is a test program created to record the elapsed time.

python

import datetime
import time


def main():
    s_time = datetime.datetime.now()
    while True:
        time.sleep(2)
        now_time = datetime.datetime.now()
        time_delta = now_time - s_time
        print(time_delta)

if __name__ == '__main__':
    main()

The execution result is as follows.

sh

pi@raspberrypi:~/Works/temp_logger/test $ python stopwatch.py
