I suspect I didn't see the definition of 'aList' on Alan's website, but
the values look different than what you posted originally.

Based on the output above, I'd say:
aList = [42,]
another = [1, 2, 7]

Whereas your definition, in your original email:
aList = [2,3]
bList = [5,7,9]

Do you see the difference between the two (aside from the different
variable names)?

In your example, that would be the 'second' item in your bList (because
lists are zero-based):
bList[2] == 9

After 'append'ing bList to aList, aList has three items.  Try this at
the python command line:
print aList[0]
print aList[1]
print aList[2]

Two of those will be integers, One will be a list.

I hope that helps.

Eric.
