Creating a timer in python

Question

import time
def timer():
   now = time.localtime(time.time())
   return now[5]


run = raw_input(\"Start? > \")
while run == \"start\":
   minutes = 0
   current_         


        

Answer 1

You're probably looking for a Timer object: http://docs.python.org/2/library/threading.html#timer-objects

Answer 2

Your code's perfect except that you must do the following replacement:

minutes += 1 #instead of mins = minutes + 1

or

minutes = minutes + 1 #instead of mins = minutes + 1

but here's another solution to this problem:

def wait(time_in_seconds):
    time.sleep(time_in_seconds) #here it would be 1200 seconds (20 mins)

Answer 3

I'd use a timedelta object.

from datetime import datetime, timedelta

...
period = timedelta(minutes=1)
next_time = datetime.now() + period
minutes = 0
while run == 'start':
    if next_time <= datetime.now():
        minutes += 1
        next_time += period

Answer 4

import time 

...

def stopwatch(mins):
   # complete this whole code in some mins.
   time.sleep(60*mins)

...

Answer 5

import time
def timer():
   now = time.localtime(time.time())
   return now[5]


run = raw_input("Start? > ")
while run == "start":
   minutes = 0
   current_sec = timer()
   #print current_sec
   if current_sec == 59:
      mins = minutes + 1
      print ">>>>>>>>>>>>>>>>>>>>>", mins

I was actually looking for a timer myself and your code seems to work, the probable reason for your minutes not being counted is that when you say that

minutes = 0

and then

mins = minutes + 1

it is the same as saying

mins = 0 + 1

I'm betting that every time you print mins it shows you "1" because of what i just explained, "0+1" will always result in "1".

What you have to do first is place your

minutes = 0

declaration outside of your while loop. After that you can delete the

mins = minutes + 1

line because you don't really need another variable in this case, just replace it with

minutes = minutes + 1

That way minutes will start off with a value of "0", receive the new value of "0+1", receive the new value of "1+1", receive the new value of "2+1", etc.

I realize that a lot of people answered it already but i thought it would help out more, learning wise, if you could see where you made a mistake and try to fix it.Hope it helped. Also, thanks for the timer.

Answer 6

import time
def timer(n):
    while n!=0:
        n=n-1
        time.sleep(n)#time.sleep(seconds) #here you can mention seconds according to your requirement.
        print "00 : ",n
timer(30) #here you can change n according to your requirement.
