模块名称 MODULE NAME
====================
::
timer
简介 DESCRIPTION
================
::
A Python timer module, containing class Timer() and decorator function timer(),
as well as some useful functions that can be used for performance analysis.
一个Python计时器模块, 其中包含Timer()类和timer()装饰器, 以及一些相关的有用函数, 可用于程序性能分析。
包含的函数和类 Functions & Classes:
===================================
类:
class Timer
"""""""""""
一个计时器类
start()
开始计时。此方法在Timer类初始化时会被自动调用。
gettime()
获取从计时开始到现在的时间。
printtime(fmt_str="用时:{:.8f}秒")
打印出从计时开始到现在的时间, 也就是获取的值。
函数:
timer(msg=None, file=sys.stdout, flush=False)::
一个装饰器, 为某个函数计时 (比使用Timer类更快、更简单)。
用法:@timer(msg="用时:{time}秒")
def func(args):
print("Hello World!")
#或:
@timer
def func(args):
print("Hello World!")
示例代码 EXAMPLES
=================
示例1:
.. code-block:: python
import timer
t=timer.Timer() #初始化Timer对象
do_something()
t.printtime() #输出执行do_something()所用时间 (也可使用t.gettime()获取所用时间)
示例2:
.. code-block:: python
#退出with语句时自动打印出所用时间。
import timer
with timer.Timer(): #在这里开始计时
do_something()
示例3:
.. code-block:: python
# 为某个函数计时
from timer import timer
@timer
def func():
print("Hello World!")
示例4:
.. code-block:: python
# 程序精确地延迟一段时间
from time import sleep
from timer import sleep as sleep2
sleep(0.0001)
sleep2(0.0001)
# 经测试表明, time模块的sleep()函数与本模块的函数相比, 有明显的延迟
版本 VERSION
============
1.2.4
**警告: 由于本模块的名称timer和pywin32库中的timer模块名称冲突，本模块已弃用和停止更新，请安装作者最新版本的timer-tool模块（https://pypi.org/project/timer-tool/）。**
