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.
1st, 2nd, 3rd revisited in Ruby

I've been updating some of my Ruby examples today (as one does on a Saturday!) and I thought back to the post I made yesteday concerning 1st, 2nd, 3rd, etc in Python.

Ruby has a case statement, even though Ruby is a bit of a cross between Python and Perl, neither of which supports the structure. Historically, it's been difficult for language authors to come up with a really good multiple way switch but actually the Ruby one is rather smart. Compare this Ruby to the Python code I wrote yesterday:

case value
when 1,21,31
  suffix = "st"
when 2,22
  suffix = "nd"
when 3,23
  suffix = "rd"
else
  suffix = "th"
end

puts "It is the #{value}#{suffix} of the month"


Oh - I'm revising this for the public Ruby course that's running on 14th and 15th December ... places still available at £550.00 (first delegate) and £440.00 (second and subsequent delegate on same running of the course / same order. Maximum of 7 delegates taken, and just 3 rooms available as I write, Hurry hurry hurry!!
