<p class="MsoNormal">Hi everyone,<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">I was playing around with the Python package “timeit” as part of teaching sorting algorithms and thought I’d send it to the list in the spirit of sharing. I don’t suggest running anything bigger than
<i>n</i>=50000 unless you’re willing to wait patiently! (For interest, <i>n</i>=50,000 takes 71 seconds using selection sort, 0.11 seconds using quicksort)<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Even if you’re not teaching Python, if you have Python installed on your computer you can use it to play around with different
<i>n</i> values to demonstrate algorithm complexity in relation to sort time.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">I’ve attached the code as a zip file in case .py files are filtered.
<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
