python用tkinter做计时器

发布时间:2022-05-29 02:28:34

⑴ 关于python计时器的问题

当range函数里面的参数为单个变量时,这个变量#代表是长度
为6就是要从0开始数到某个元素为止,这些元素的个数一共是6个,如果按照c语言的话可能是这么写的for(i=0
;i<6;i++)。写range(6)和range(0,5)没有区别。

⑵ python怎么写计时器用面向对象和多向进程

timeit

⑶ python如何实现计时

用python实现计时器功能,代码如下:
''' Simple Timing Function.
This function prints out a message with the elapsed time from the
previous call. It works with most Python 2.x platforms. The function
uses a simple trick to store a persistent variable (clock) without
using a global variable.
'''
import time
def r( op=None, clock=[time.time()] ):
if op != None:
ration = time.time() - clock[0]
print '%s finished. Duration %.6f seconds.' % (op, ration)
clock[0] = time.time()
# Example
if __name__ == '__main__':
import array
r() # Initialise the timing clock
opt1 = array.array('H')
for i in range(1000):
for n in range(1000):
opt1.append(n)
r('Array from append')
opt2 = array.array('H')
seq = range(1000)
for i in range(1000):
opt2.extend(seq)
r('Array from list extend')
opt3 = array.array('H')
seq = array.array('H', range(1000))
for i in range(1000):
opt3.extend(seq)
r('Array from array extend')
# Output:
# Array from append finished. Duration 0.175320 seconds.
# Array from list extend finished. Duration 0.068974 seconds.
# Array from array extend finished. Duration 0.001394 seconds.

⑷ python 如何添加计时器

使用time模块
程序最开始的时候使用time.time()得到一个时间
然后,再需要查看时间的地方调用一下time.time(),得到另一个时间,然后两个时间相减就可以得到程序执行的时间,得到的是秒数,可以自己算一下得到分钟这类的

⑸ Python2.7.13怎么编计时器

用python实现计时器功能,代码如下:

''SimpleTimingFunction.

previouscall.ItworkswithmostPython2.xplatforms.Thefunction
(clock)without
usingaglobalvariable.
'''
importtime
defr(op=None,clock=[time.time()]):
ifop!=None:
ration=time.time()-clock[0]
print'%sfinished.Duration%.6fseconds.'%(op,ration)
clock[0]=time.time()
#Example
if__name__=='__main__':
importarray
r()#Initialisethetimingclock
opt1=array.array('H')
foriinrange(1000):
forninrange(1000):
opt1.append(n)
r('Arrayfromappend')
opt2=array.array('H')
seq=range(1000)
foriinrange(1000):
opt2.extend(seq)
r('Arrayfromlistextend')
opt3=array.array('H')
seq=array.array('H',range(1000))
foriinrange(1000):
opt3.extend(seq)
r('Arrayfromarrayextend')
#Output:
#Arrayfromappendfinished.Duration0.175320seconds.
#Arrayfromlistextendfinished.Duration0.068974seconds.
#Arrayfromarrayextendfinished.Duration0.001394seconds.

题主空闲的时候可以多看看Python的相关教程,黑马程序员再往上有许多免费的教程,想学习的可以下载下来多看看,多学习学习,以后类似的问题就可以迎刃而解了。https://..com/question/1051689931722045579.html?fr=android_app&share_time=1499421328373

⑹ 怎么用python写倒计时的代码

importtime
time=int(input('倒计时时间(分)'))
b=time*60
foriinrange(b):
print('%d分%d秒'%(b/60,b%60))
time.sleep(1)
b-=1

⑺ python的计时器

你可以用Twisted来实现,源代码如下:

from twisted.internet import task
from twisted.internet import reactor

#set global variables
g = 0
def run():
global g
g = g + 1
print 'the global value g is:%s'%g
#add function run to twisted's looping call
l = task.LoopingCall(run)
#set interval to 5*60 seconds
l.start(5*60)
reactor.run()
要运行这段代码你得装twisted和zope中关于interface的定义,上google搜搜载一个装了就可以了。

⑻ 用python 计时器怎么做,

用python实现计时器功能,代码如下:

'''SimpleTimingFunction.

previouscall.ItworkswithmostPython2.xplatforms.Thefunction
(clock)without
usingaglobalvariable.
'''
importtime
defr(op=None,clock=[time.time()]):
ifop!=None:
ration=time.time()-clock[0]
print'%sfinished.Duration%.6fseconds.'%(op,ration)
clock[0]=time.time()
#Example
if__name__=='__main__':
importarray
r()#Initialisethetimingclock
opt1=array.array('H')
foriinrange(1000):
forninrange(1000):
opt1.append(n)
r('Arrayfromappend')
opt2=array.array('H')
seq=range(1000)
foriinrange(1000):
opt2.extend(seq)
r('Arrayfromlistextend')
opt3=array.array('H')
seq=array.array('H',range(1000))
foriinrange(1000):
opt3.extend(seq)
r('Arrayfromarrayextend')
#Output:
#Arrayfromappendfinished.Duration0.175320seconds.
#Arrayfromlistextendfinished.Duration0.068974seconds.
#Arrayfromarrayextendfinished.Duration0.001394seconds.

⑼ 使用Python,实现程序运行计时的数码管表示

clock[0] = time.time()
# Example
if __name__ == '__main__':
import array
r() # Initialise the timing clock
opt1 = array.array('H')
for i in range(1000):
for n in range(1000):
opt1.append(n)
r('Array from append')
opt2 = array.array('H')
seq = range(1000)
for i in range(1000):
opt2.extend(seq)
r('Array from list extend')
opt3 = array.array('H')
seq = array.array('H', range(1000))
for i in range(1000):
opt3.extend(seq)
r('Array from array extend')
# Output:

# Array from list extend finished. Duration 0.068974 seconds.
# Array from array extend finished. Duration 0.001394 seconds.

⑽ python计时器问题

import time
print('按下回车开始计时,按下 Ctrl + C 暂停/停止计时。')
while True:
input("")
starttime = time.time()
print('开始')
pausetime=0
while True:
try:
totaltime=int((time.time()-pausetime-starttime))
print('【'+str(int((time.time()-pausetime-starttime)*0.66)),'进度】',int((time.time()-pausetime-starttime)/60),'分', int((time.time()-pausetime-starttime)%60), '秒',end=' ')
time.sleep(1)
except KeyboardInterrupt:

print('【' + str(int((time.time() -pausetime- starttime) * 0.66)), '进度】', int((time.time()-pausetime - starttime) / 60), '分',
int((time.time() -pausetime- starttime) % 60), '秒', '...暂停中 按回车继续,输入Q停止计时',end=' ') pausetime_start=time.time()

s=input("")
if s.strip().upper()=='Q':
pausetime_end = time.time()
pausetime = pausetime_end - pausetime_start + pausetime
print('结束')
endtime = time.time()
print('总时间:', round(endtime - pausetime - starttime, 2), '秒 ')
exit(0)
elif s.strip().upper()=='':
pausetime_end=time.time()
pausetime=pausetime_end-pausetime_start+pausetime
