Do you mean something like this:

>>> A=[1,2,3]
>>> AB=[4,5,6]
>>> ABC=[7,8,9]
>>> ABCD=[1,2,3]
>>> ABCDE=[4,5,6]
>>> ABCDEF=[7,8,9]
>>> [name for name in locals() if name.startswith('ABCD')]
['ABCD', 'ABCDE', 'ABCDEF']

You can get the names of the arrays in the current scope using locals()
and/or globals(), so regexes instead of the simple .startswith() should be
easy too.

Cheerio, Marc.
