For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
Profiling your Python program

Python's profiler lets you run code and log statistics, and the pstats module allows you to anaylse the resulting statistics. New example from last week's Intermediate Python Course is [here].

  import cProfile
  import pstats
  
  import railway
  
  cProfile.run("railway.test_code()","profile.out")
  
  result = pstats.Stats("profile.out")
  result.sort_stats("ncalls")
  
  result.print_stats()
  result.print_callees()


As ever with Python, the code example is largely self-describing ... take a look at the source (linked above) to show you some sample output too. The call being profiled is [here] amd the data may be viewed [here]. Data can be downloaded from [here] (that way tabs and spaces come through correct if you want to run the program!)

This is a page archived from The Horse's Mouth at http://www.wellho.net/horse/ - the diary and writings of Graham Ellis. Every attempt was made to provide current information at the time the page was written, but things do move forward in our business - new software releases, price changes, new techniques. Please check back via our main site for current courses, prices, versions, etc - any mention of a price in "The Horse's Mouth" cannot be taken as an offer to supply at that price.
