then foo is NOT a variable, necessarily. If you guys can define for me
what a variable is and what qualifications you have to back you, I can
pass this along to, hopefully, convince hi

a +
when you use a = a + 'world' python sees it as an error because of
different type.
But when you use a += 'world'

you're code become:
a += 'world' # a += list('world')
It really helpfull if you stick to use append instead of +=
