I see David using a lot of for loops like this, usually in a table:
for (singular variable) in (plural variable)
for registrant in registrants
He doesn't actually declare the singular variable anywhere. He would only assign something for the plural variable.
Shouldn't he also need to declare what the singular variable too? Or is python just so smart to know the difference between singular and plural variables?
(Sorry variables are very much C programming words aren't they.. what are python's instance?.... haha)
