Create a timer in python11/28/2023 ![]() ![]() I see the question has already been answered, but still want to add my 2 cents for the same. Would grab the globals function_to_repeat, var1 and var2 from your script and pass those to the function each repetition. 'from _main_ import function_to_repeat, var1, var2', Use the setup argument to either import or create those dependencies, and pass them into your function: def function_to_repeat(var1, var2): You should move setup code out of the repeated function for example, you should connect to the database first, then time only the queries. This would disable the garbage collection, repeatedly call the function_to_repeat() function, and time the total duration of those calls using fault_timer(), which is the most accurate available clock for your specific platform. That said, you can simply put your code in a function and run that function with timeit.timeit(): def function_to_repeat():ĭuration = timeit.timeit(function_to_repeat, number=1000) Disk I/O is slow, so I'd take that out of the test if all you are going to tweak is the database query.Īnd if you need to time your database execution, look for database tools instead, like asking for the query plan, and note that performance varies not only with the exact query and what indexes you have, but also with the data load (how much data you have stored). You'd better specify the number of runs because the default, a million, may be high for your use case (leading to spending a lot of time in this code -).įocus on one specific thing. Since 3.5 the globals parameter makes it straightforward to use timeit it with functions that take parameters: timeit.timeit('foobar(x,y)', number=1000, globals = globals()) Specifically, if the function you want to time is a parameter-less one called foobar you can use timeit.timeit (2.6 or later - it's more complicated in 2.5 and before): timeit.timeit('foobar()', number=1000) Once you have your code working correctly is the correct point at which to think about using timeit on it! a function that makes or receives a connection and performs 100 or 500 or whatever number of updates on that connection, then closes the connection. Get an ||logic:if then|| block from Logic and put it in the ||input:on button pressed||.Quite apart from the timing, this code you show is simply incorrect: you execute 100 connections (completely ignoring all but the last one), and then when you do the first execute call you pass it a local variable query_stmt which you only initialize after the execute call.įirst, make your code correct, without worrying about timing yet: i.e.In Input, find an ||input:on button pressed|| an put it somewhere on the workspace.The time count of seconds will increase by 10 each time the button is pressed. We’ll use button A to add 10 seconds to our time count. We’ll use one button for adding 10 seconds and another button for adding just 1 second. We’ll use the buttons to set the amount of time by adding both 10 seconds and single seconds. There has to be a way to set the time on your watch. Let seconds = 0 Set the time with buttons Place the variable into the ||basic:on start|| block. Drag out a ||variables:set to|| block and change the name with the dropdown to seconds. Ok, in Variables click on Make a Variable.Go into Basic in the toolbox and pull an ||basic:on start|| on to the workspace.We need a variable to keep track of how many seconds are left on the watch. ![]() Duration: ~10 minutes Make the time variable Let’s make a countdown timer and see the seconds tick by on your micro:bit watch. ![]()
