traverse

def traverse(o, tree_types=(list, tuple)):    if isinstance(o, tree_types):        for value in o: for subvalue in traverse(value, tree_types):     yield subvalue    else:        yield odata = [(1,1,(1,1,(1,"1"))),(1,1,1),(1,),1,(1,(1,("1",)))]print list(traverse(data))# prints [1, 1, 1, 1, 1, '1', 1, 1, 1, 1, 1, 1, 1, '1']for value in traverse(data):    print repr(value)# prints# 1# 1# 1# 1# 1# '1'# 1# 1# 1# 1# 1# 1# 1# '1'
