Python uses ** operator for what is superscript in math and [] operator for what is subscript.  Allowing sub/superscripts in identifiers will create confusion.  (It is not uncommon to mix typeset math with python code in generated documentation.)

If you have many identifiers with subscripts, I would recommend using a list or a dictionary and call them a[1], a[2], etc. instead of a<sub>1, a<sub>2.
