A class for timing code. A Stopwatch object can be used to time code using its start and
stop methods:
from et_stopwatch import Stopwatch stopwatch = Stopwatch() # create and start the stopwatch sleep(1) stopwatch.stop() print(stopwatch) stopwatch : 1.003744 s
Use as a context manager:
with Stopwatch(message='This took') as sw: # using a custom message
for i in range(3):
sleep(1)
print(i, sw.stop(), 's') # stop() returns the time since the last call to start|stop in seconds
0 1.004943
1 1.004948
2 1.003404
This took :
total : 3.013295 s
minimum: 1.003404 s
maximum: 1.004948 s
mean : 1.004432 s
stddev : 0.000727 s
count : 3
Since stop was called more than once, some statistics are printed.
Use as a decorator:
@Stopwatch(name="say_hi_and_sleep_two_seconds", ndigits=3) # custom message, print only 3 digits.
def say_hi_and_sleep_two_seconds():
print("hi")
sleep(2)
say_hi_and_sleep_two_seconds()
hi
say_hi_and_sleep_two_seconds : 2.003 s
