Let's make a function to divide two numbers, that's very trusting about its input: def divide(x, y) return x/y end This will work fine for a lot of inputs: > puts divide(10, 2) 5 But not all > puts divide(10, 0) ZeroDivisionError: divided by 0 > puts divide(10, 'a') TypeE...

You can save the error if you want to use it in the rescue clause def divide(x, y) begin x/y rescue => e puts "There was a %s (%s)" % [e.class, e.message] puts e.backtrace end end > divide(10, 0) There was a ZeroDivisionError (divided by 0) from ...
