Do you execute the script from the command line on Linux or UNIX  In that case  you could just use   time   script py

Use the timeit module  It s very easy  Run your example py file so it is active in the Python Shell  you should now be able to call your function in the shell  Try it out to check it works   gt  gt  gt fun input  output   Good  that works  now import timeit and set up a timer   gt  gt  gt import timeit  gt  gt  gt t   timeit Timer  example fun input    import example    gt  gt  gt    Now we have our timer set up we can see how long it takes   gt  gt  gt t timeit number 1  some number here   And there we go  it will tell you how many seconds  or less  it took to execute that function  If it s a simple function then you can increase it to t timeit number 1000   or any number   and then divide the answer by the number to get the average   I hope this helps

use the time and datetime packages   if anybody want to execute this script and also find out how much time it took to execute in minutes  import time from time import strftime from datetime import datetime  from time import gmtime  def start time              import time     start time   time time       return start time   def end time          import time     end time   time time       return end time   def Execution time start time  end time        import time     from time import strftime     from datetime import datetime      from time import gmtime    return strftime   H  M  S  gmtime int     0f   format float str  end time-start time          start time   start time      your code here    i for i in range 0 100000000     your code here   end time   end time    print  Execution time is     Execution time start time end time     The above code works for me  I hope this helps

import time   startTime   time time     Your code here   print   The script took  0  second    format time time   - startTime     The previous code works for me with no problem

What I usually do is use clock   or time   from the time library  clock measures interpreter time  while time measures system time  Additional caveats can be found in the docs   For example   def fn        st   time       dostuff       print  fn took   2f seconds     time   - st    Or alternatively  you can use timeit  I often use the time approach due to how fast I can bang it out  but if you re timing an isolate-able piece of code  timeit comes in handy   From the timeit docs   def test         Stupid test function      L          for i in range 100           L append i   if   name       main         from timeit import Timer     t   Timer  test      from   main   import test       print t timeit     Then to convert to minutes  you can simply divide by 60  If you want the script runtime in an easily readable format  whether it s seconds or days  you can convert to a timedelta and str it   runtime   time   - st print  runtime    timedelta seconds runtime    and that ll print out something of the form  D day s     H H MM SS  UUUUUU   You can check out the timedelta docs   And finally  if what you re actually after is profiling your code  Python makes available the profile library as well
