9 Απρ 2014 · import time start_time = time.time() # Your code here print time.time() - start_time, "seconds" There are profilers available that can also help. If I have a small script that looks like this. print "Hello, World!" And want to profile it >python -m cProfile test.py Hello, world!
Using time.time to measure execution gives you the overall execution time of your commands including running time spent by other processes on your computer. It is the time the user notices, but is not good if you want to compare different code snippets / algorithms / functions / ... More information on timeit: Using the timeit Module
This should be the correct answer. I believe anybody searching for a count up timer is looking for this. The other answers also work, but if you leave the window at some point it seems the timer is sent into hibernation, so the time is not counting continuous. –
13 Οκτ 2009 · time.perf_counter() Return the value (in fractional seconds) of a performance counter, i.e. a clock with the highest available resolution to measure a short duration. It does include time elapsed during sleep and is system-wide. time.process_time()
11 Μαΐ 2010 · The third question asks: "What about **time taken = 4 45025, does that mean 4 seconds and 25 msec?" My third answer is the time taken is 4 seconds and 45025 microseconds, that is 4.045025 seconds, which shows that OP has altered the tasks performed by the two functions which he previously timed.
@undefined: Not just Linux, it's actually the C standard that says "The clock function determines the processor time used.". I suppose on Windows you can simply say that the implementation's best approximation to processor time used is wall-clock time used. –
13 Ιουν 2022 · Why do you need a counter? Just initialise start_time variable to None in the beginning, then in your if-block you check whether it is set, if it isn't you set it to time.time(). In the else-block set end_time to time.time() again and calculate the difference. EDIT
24 Δεκ 2012 · The Stopwatch measures elapsed time by counting timer ticks in the underlying timer mechanism. If the installed hardware and operating system support a high-resolution performance counter, then the Stopwatch class uses that counter to measure elapsed time. Otherwise, the Stopwatch class uses the system timer to measure elapsed time.
Thanks! This worked great. One note for others who may be using timeit for the first time, you will need to import locally defined symbols via timeit's setup parameter. For example (if myOwnFunc was locally defined and what you wanted to time): print timeit.timeit('myOwnFunc()', setup='from __main__ import myOwnFunc', number=1). Without the ...
5 Αυγ 2017 · As you can see in the linked question, you have three choices. Either pygame.time.get_ticks(), the dt = clock.tick(fps) solution or pygame.time.set_timer. I usually use the dt (delta time) approach, because I need to pass the dt to my sprite classes as well to make them frame rate independent (multiply their velocity by dt). –
