[英]How to convert a Python multilevel dictionary into tuples?
我有一个多级字典,下面的例子,它需要以相反的顺序转换成元组,即最里面的元素应该首先用于创建元组。
{a: {b:c, d:{e:f, g:h, i:{j:['a','b']}}}}
输出应该是这样的:
[(j,['a','b']), (i,j), (g,h), (e,f), (d,e), (d,g), (d,i), (b,c), (a,b), (a,d)]
你去吧,这将产生你想要的(也经过测试):
def create_tuple(d):
def create_tuple_rec(d, arr):
for k in d:
if type(d[k]) is not dict:
arr.append((k, d[k]))
else:
for subk in d[k]:
arr.append((k, subk))
create_tuple_rec(d[k], arr)
return arr
return create_tuple_rec(d, [])
# Running this
d = {'a': {'b':'c', 'd':{'e':'f', 'g':'h', 'i':{'j':['a','b']}}}}
print str(create_tuple(d))
# Will print:
[('a', 'b'), ('a', 'd'), ('b', 'c'), ('d', 'i'), ('d', 'e'), ('d', 'g'), ('i', 'j'), ('j', ['a', 'b']), ('e', 'f'), ('g', 'h')]
