ttictoc
Time execution of blocks of code.
TocToc
The easiest way to time something is with tic and toc
from ttictoc import tic,toc
tic() # Start timing
# some code
elapsed = toc() # Gets the elapsed time until this moment
print('Elapsed time:',elapsed)You can execute multiple tocs and will be linked to the tic time.
Also, each time tic is executed the time holded by tic will be
updated.
import time
from ttictoc import tic,toc
tic() # Start timing
time.sleep(1)
tic() # Reset the starting time
time.sleep(1)
print(toc()) # Prints ~1 seconds
time.sleep(1)
print(toc()) # Prints ~2 secondsTimer Class
The Timer class can be used to have a single and multiple timers. Examples seen with tic,toc are also valid with Timer start,stop
import time
from ttictoc import Timer
# General timer
t = Timer()
t.start() # Starts the general timer
time.sleep(1)
elapsed = t.stop()
print('Elapsed time:',elapsed)
# Multiple timers
t.start('t0')
for i in range(2):
tname = 't'+str(i+1)
t.start(tname)
time.sleep(1)
elapsed = t.stop(tname)
print('[INSIDE LOOP][{}] Elapsed time: {}'.format(tname,elapsed))
t.stop('t0')
print('[OUTSIDE LOOP][{}] Elapsed time: {}'.format('t0',t.elapsed['t0']))
print('[OUTSIDE LOOP][{}] Elapsed time: {}'.format('t1',t.elapsed['t1']))
print('[OUTSIDE LOOP][{}] Elapsed time: {}'.format('t2',t.elapsed['t2']))Context manager
You can also use it as context manager
import time
from ttictoc import Timer
# Default
with Timer():
time.sleep(1)
# With out verbose
with Timer(verbose=False) as T:
time.sleep(1)
print('Elapsed time:',T.elapsed)
# With default verbose message
with Timer(verbose_msg=f'[User msg][{time.time()}] Elapsed time: {{}}'):
time.sleep(1)Specify timing method
By default, Timer (and tic,toc) use timeit.default_timer. However, the timing function can be selected as follow.
import time
from ttictoc import Timer
t = Timer(func_time=time.clock)
t.start()
time.sleep(5)
elapsed = t.stop()
print('Elapsed time:',elapsed)
