# 统计耗时
from time import clock
from time import perf_counter
from time import sleep
#方式1 --》使用clock()
# DeprecationWarning: time.clock has been deprecated in Python 3.3 and will be removed from Python 3.8: use time.perf_counter or time.process_time instead
# Python time.clock在Python3.3废弃，在Python3.8中将被移除
#方式2 --》使用perf_counter()
def time_test():
start = perf_counter()
sleep(2)
end = perf_counter()
print('{}.{} : {} second'.format(time_test.__module__, time_test.__name__, end - start))
time_test()
#方式3 --》使用装饰器
from functools import wraps
def timethis(func):
@wraps(func)
def wrapper(*args, **kwargs):
start = perf_counter()
r = func(*args, **kwargs)
end = perf_counter()
print('{}.{} : {}'.format(func.__module__, func.__name__, end - start))
return r
return wrapper
@timethis
def time_test1():
sleep(2)
time_test1()
