If you are developing your web application or any program within Python and you need to some help and suggestion then I would be very glad.

According to query,you need some statement to display after point of time.The available library functions can help you much more.You need to use those resources to achieve your concept.

The Number of library functions are available to help you for executing what you want.This is some of the function like Time.sleep,sleep,time for advance management of the events.

Time.sleep function

The Time.sleep function is used to sleep the connected statement in the program for a given time.According to the nature of function time.sleep(), It restricts the execution of program according to parameter for the time period.

The example for this event -

 while True:

      checkSomething()

 Print 'Welcome...'               
 time.sleep(2)
 print 'Welcome...after two second'

Threads in Python:

If you need to execute so many processes which requires to execute at asingle point of time means overall ,you want to perform several things at the same time,then threads can help in this case.

It allows you to construct the list of processes which you need to execute.You can set up a number of processes or sub-processes and each of which can be run independently but which can be brought back together later and/or co-ordinated as they run.

The thread concept is used for large and heavy loaded application.

Constructing thread in Python

The thread can be constructed in the Python program.Just construct a program which requires a network connection and need to find the availability of computers in the network.

The code which will show you the position of the 10 computers in the network :

import os
import re
import time
import sys

lifeline = re.compile(r"(\d) received")
report = ("No response","Partial Response","Alive")

print time.ctime()

for hst in rng(60,70):
   ip = "192.168.200."+str(hst)
   pingaling = os.popen("ping -q -c2 "+ip,"r")
   print "Testing ",ip,
   sys.stdout.flush()
   while 1:
      line = pingaling.readline()
      if not line: break
      igot = re.findall(lifeline,line)
      if igot:
           print report[int(igot[0])]

print time.ctime()

Sleep function in Python:

The sleep function is used with different Import behaviors but here i will show you the code which is constructed with time.The code will follow the sequence as follows -

.
.
.
 
img3 = "Helinks.GIF"
photo3 = PhotoImage(file=img3)
 
time.sleep(10)
 
img4 = "Tom.GIF"
photo4 = PhotoImage(file=img4)
