How can I still using this method and can use yield?def timing(f): def wrap(*args, **kwargs): time1 = time.time() ret = f(*args, **kwargs) time2 = time.time() print '%s function took %0.3f ms' % (f.func_name, (time2-time1)*1000) return ret return wrapwhat's the disadvantage of writing it yourself? timeit doesn't work well with Apache Spark because you have to import all the Spark dependencies, and who wants to make a big old string that does that? Given a function you'd like to time, test.py: def foo(): # print "hello" return "hello" the easiest way to use timeit is to call it from the command line: % python -mtimeit -s'import test' 'test.foo()' 1000000 loops, best of 3: 0.254 usec per loop Active 1 month ago.

The first way passed in the Python callable We can use decorators to measure functions with arguments. Summary and Tips. All you need is to wrap your function up using decorators. By using our site, you acknowledge that you have read and understand our
I want to create a python function to test the time spent in each function and print its name with its time, how i can print the function name and if there is another way to do so please tell meHowever if you wanted to write your own timing method strictly to learn, here is somewhere to get started using a decorator.And the usage is very simple, just use the @timing decorator:This is almost the same with @Mike's method. Basically, it's the inverse function of localtime(). Featured on Meta
Python time measure function. More explanation here: The only case where you might be interested in writing your own timing statements is if you want to run a function only once and are also want to obtain its return value.Timeit has two big flaws: it doesn't return the return value of the function, and it uses eval, which requires passing in extra setup code for imports.
If you have some part of code that you don't what to make it a function, then you can choose the second method.Looks not so great...What if you are in Python 2, which has no Instead, using the second method fits here very well:Its also possible to send arguments to the functions. Ask Question Asked 9 years, 4 months ago. Pythom time method time() returns the time as a floating point number expressed in seconds since the epoch, in UTC.. Function strptime() can parse 2-digit years when given %y format code. Stack Overflow works best with JavaScript enabled
In addition, remember that the default number of executions is 1000000 which could increase the total execution time a lot for certain complex functions.

When 2-digit years are parsed, they are converted according to the POSIX and ISO C standards: values 69–99 are mapped to 1969–1999, and values 0–68 are mapped to 2000–2068. Description.
Here I add Using the first method, you can eaily comment out the decorator to get the normal code.

Let’s add a bare-bones Python timer to the example with time.perf_counter().Again, this is a performance counter that’s well-suited for timing parts of your code.. perf_counter() measures the time in seconds from some unspecified moment in time, which means that the return value of a single call to the function isn’t useful.
