python - How to print iterations per second? -


i have small python script sends post requests server , gets response.

it iterates 10000 times, , managed print current progress in command prompt using:

code=current_requestnumber print('{0}/{1}'.format(str(code),"10000"),end="\r")

at end of each loop.

because involves interaction webserver, show current average speed next (updated every 2 seconds).

an example @ bottom of command prompt this:

(1245/10000), 6.3 requests/second

how achieve this?

you can total average number of events per second this:

#!/usr/bin/env python3  import time import datetime dt  start_time = dt.datetime.today().timestamp() = 0 while(true):     time.sleep(0.1)     time_diff = dt.datetime.today().timestamp() - start_time     += 1     print(i / time_diff)

which in example print approximately 10. please note used timestamp method of datetime availble in python 3.

now, if calculate "current" number of events per second, on last 10 events, can this:

#!/usr/bin/env python3  import time import datetime dt  last_time = dt.datetime.today().timestamp() diffs = [] while(true):     time.sleep(0.1)      # add new time diff list     new_time = dt.datetime.today().timestamp()     diffs.append(new_time - last_time)     last_time = new_time      # clip list     if len(diffs) > 10:         diffs = diffs[-10:]      print(len(diffs) / sum(diffs))

here, i'm keeping list of durations of last 10 iterations on can use average number of events per second.

i have method allows user access comment have made on site. have post method lets them update comment. my normal solution send entire comment model through, let them update it, update on database when post back. involve sending commentid through in hiddenfor , can manipulated. how can verify commentid sent in get method same i'm getting in post , not able alter comment wish? how can verify commentid sent in method same i'm getting in post? basically have validate following things in post - user logged-in user. authenticated users post comments. commentid in post , should valid commentid , should present in database. userid associated logged-in user should same userid associated comment . comment should contain userid column, can check @ time of update. to make sure update happens comment has been sent in get - hold commentid in session , in post action compare commentid value in session .
