i woule a way to parse a line python source like split

[Skaperen]

i would like to parse a line of python source instead of merely split it:

    line = "blank=' '"
    parts = line.split()
    parts -> ["blank='","'"]
    pieces = ??parse??(line)
    pieces -> ["blank"."=","' '"]

i want to get what pieces ends up with.

"a[0]=int(ab[16])+2" -> ["a","[","0","]","=","int","(","ab","[","16","]",")","+","2"]

i need to parse some python source only one line at a time to make some edits by other scripts, although i am not sure how best to handle continuations. comments should be one big string. if white spaces are always included, that's ok.
