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. |
Ruby - where one statement ends and the next begins
In Ruby, you can end your statements with a ;, but it's more usual to simply let them end at the end of a line. Ruby can usually identify where a statement ends and if it clearly doesn't end on one line, it carries on to the next.
Just occasionally, this can be little bit of a trap. Look at this code with teo apparently identicsl statements giving different results. Why?
a = 5
b = a
+ 6
puts b
b = a +
6
puts b
__END__

The answer is that Ruby has split the first "statement" into two - whereas the second example clearly continued from one line to the next and was treated as a single statement.
It's great to be teaching Ruby this week - see our Ruby Courses ... and I'll be going on to Cucumber and Gherkin over the next couple of days. (written 2015-05-26, updated 2015-05-27)
