Three downvotes for this question? And no comments explaining to the new user what's wrong? Neither the headline he chose nor his text uses any words that would help him find the duplicate easily (e.g. "flatten"), so I doubt it's due to negligence. Might be bad luck, or lacking vocabulary. +1 to compensate. And welcome to SO betul, better luck with next question. :) — Lauritz V. Thaulow, May 22 '11 at 19:31

Like this:

startlist=[[[13, 7], 90], 2, [1, 100], 8, 6]
endlist=[]

def flatten(l):
    for item in l:
        if type(item) in (type([]),type(())):
            flatten(item)
        else:
            endlist.append(item)
