I have a tree-like data structure, the basic elements are hash tables,
and they are grouped into lists, like [[{'a':1},[{'b':2}]]].
And I want to flat the lists and visit hash table one by one, like {'a':1},
{'b':2}.
But my program didn't work as I wish. When it entered the 2nd
flat_yield, it threw a GeneratorExit. Is there anything wrong?
Thank you very much!

def flat_yield(tbl_list):
for t in tbl_list:
if type(t) == type({}):
yield t
elif type(t) == type([]):
flat_yield(t)
a = [[{'a':1},[{'b':2}]]]
for i in flat_yield(a):
print i
