Can you cite a common definition of “array” other than a bare minimum of being randomly accessible? (Nothing else is pinned down. Fixed vs variable length, single vs mixed type, or even underlying data structure (cf NSArray)).

By the only universal definition I can think of, python lists are arrays.

Python lists most certainly meet the mathematical definition of array (ie name by index)

It seems you're right. Python lists are arrays -- I didn't know that.

That makes my point even stronger. The article about "Python Arrays" directly claims that Python Arrays don't exist, which is apparently wrong!

The whole point is that I came away from the article believing information that is false.
