sleep
time.sleep(secs) stops execution of the script for secs seconds.
#!/usr/bin/python3
import time
t_start = time.time()
print("Time going to sleep for four seconds.")
time.sleep(4)
print("Just woke up, after {:f} seconds".format(time.time() - t_start))
perf_counter
time.perf_counter allows to quickly measure the time something takes.
#!/usr/bin/python3
import time
def doSomething():
ret = 0
for i in range(0, 100):
ret += i**i
return ret
t0 = time.perf_counter()
print(doSomething())
t1 = time.perf_counter()
tExec = t1 - t0
print(f"Execution of doSomething took {tExec:.7f} seconds.")
For more accurate timings, the
timeit module should probably be used.
