[Tutor] Dynamic-ish naming of variables?

[Liam Clarke]

Hi Danny,

It has been said that Kiwis (the people, not bird or Americanised name
of a fruit) are a fairly unemotional & laidback bunch of people. Well,
not this misnamed fruit (which was originally called a chinese
gooseberry).

I just did an impression of an overexcitable Mediterranean soccer fan
watching his 99th ranked in the world team come back to win in the
penalty shoot out against Brazil.

I tried the code as follows - 

def on_PastReportButton_mouseClick(self, event):
        nameList=['CheckBox1']
        print "This won't be doing jack until you've run the first option."
        self.testWindow=model.childWindow(self, test.testDict)

        for name in nameList:
            if self.testWindow.components[name].checked: print "It vorked"

and I got - 

This won't be doing jack until you've run the first option.
It vorked

So a thousand thanks Danny, my brain was going seriously curly trying
to figure that one out.

Regards,

Liam Clarke
