Tic-Tac -Toe (along with a lot of other games) involves looking ahead and trying to figure out what the person playing against you might do next. But if you really wrap your brain around it, you'll discover that Tic-Tac-Toe isn't quite as simple as you think! It's a really simple game, right? That's what most people think.
Tic toc how to#
Install it with a setup.py file: # setup.pyįrom re import setup, Extensionįrom the command line, run python setup.py build and Bob's your uncle.You probably already know how to play Tic-Tac-Toe. 1, // size of per-interpreter state of module -1 if module keeps state in global variables "A timer function analogous to MATLAB's tic-toc.", // module documentation, may be NULL Static PyObject* tic(PyObject *self, PyObject *args) , It also allows one to change the format string of the toc statement to display additional information, which I liked about Eli's Timer class.įor some reason I got concerned with the overhead of a pure Python implementation, so I tested a C extension module as well: #include Since this works by pushing the starting times on a stack, it will work correctly for multiple levels of tics and tocs. Print fmt % (time() - _tstart_stack.pop()) After trying lots of Python cleverness, here is the simple solution that I found worked best: from time import time Moreover, there may be the need to measure the time between points in different functions, which wouldn't work with the with statement. I went with Eli Bendersky's Timer class, but wasn't fully happy, since it required me to change the indentation of my code, which can be inconvenient in some editors and confuses the version control system. I felt like spamming tics and tocs in the sources while testing interactively would be the fastest way to reveal the bottlenecks. However, a use case for tic-toc-like functionality arose when I tried to profile calculations that were interactively driven, i.e., by the user's mouse motion in a GUI. Usually, IPython's %time, %timeit, %prun and %lprun (if one has line_profiler installed) satisfy my profiling needs quite well. Toc() # returns "Elapsed time: 3.00 seconds." Toc() # returns "Elapsed time: 2.00 seconds." Toc() # returns "Elapsed time: 1.00 seconds."
Tic toc series#
If you have a series of commands that you want to time, then you can write tic() Toc() # returns "Elapsed time: 8.00 seconds."Īctually, you do not even need to use tic() each time. Toc2() # returns "Elapsed time 2: 5.00 seconds." Now you should be able to time two separate things: In the following example, we time the total script and parts of a script separately. # Records a time in TicToc2, marks the beginning of a time interval Print( "Elapsed time 2: %f seconds.\n" %tempTimeInterval )
Tic toc generator#
# Prints the time difference yielded by generator instance TicToc2 (I will provide a concrete example) TicToc2 = TicTocGenerator() # create another instance of the TicTocGen generator For instance, while timing a script, we can now time each piece of the script seperately, as well as the entire script. Here, you could create another instance of the TicTocGenerator to keep track of multiple operations, or just to time things differently. Toc() # returns "Elapsed time: 5.00 seconds."Īctually, this is more versatile than the built-in Matlab functions. That's it! Now we are ready to fully use tic() and toc() just as in Matlab. # Records a time in TicToc, marks the beginning of a time interval Print( "Elapsed time: %f seconds.\n" %tempTimeInterval ) # Prints the time difference yielded by generator instance TicToc # This will be the main function through which we define both tic() and toc() TicToc = TicTocGenerator() # create an instance of the TicTocGen generator Yield tf-ti # returns the time difference # Generator that returns time differences
Tic toc code#
Simply insert the following code at the top of your script. With the help of this thread I was able to construct an exact analog of the Matlab tic() and toc() functions.
I had the same question when I migrated to python from Matlab.
