python - 展平嵌套数组，但也在 python 中附加来自另一个数组的信息

Question

您好，我目前正在研究机器学习，这对我来说有些复杂。这是一个字典，其中包含'data'和'name'数组，子数组的数量相同，这意味着它们通过相同级别和相同位置的数组相互链接。 for example , data [-12.746249259898983, -40.618078412505398, -53.765980530841738, 5.2261728305123398, 0.12162578441442624, -5.7948531230422988, -449155.5052490317, 0.91963697398417421]'s total name is 100, and data -12.746249259898983 which inside that array 's name is '100.0 '. 但是，有些名称可以表示单级数组或嵌套数组。

 'name': [[100, 101, 102, 103, 104, 105], [106, 107, 108], [109, 110, 111, 112, 113, 114, 115, 116], [200, 201, 202, 203, 204, 205], [206, 207, 208], [209, 210, 211, 212, 213, 214, 215, 216], [300, 301, 302, 303, 304, 305], [306, 307, 308], [309, 310, 311, 312, 313, 314, 315, 316], [400, 401, 402, 403, 404, 405], [406, 407, 408], [409, 410, 411, 412, 413, 414, 415, 416], [500, 501, 502, 503, 504, 505], [506, 507, 508], [509, 510, 511, 512, 513, 514, 515, 516]]}

现在我想将数据展平并将它们全部放在底层，但是，一旦我这样做了，名称就会不匹配。

更普遍的(提醒它自己的数据可能会得到更多的嵌套级别，但地址不会)，如果我得到:{'数据':[[[1],[2,3,[4]]],[[5,6],[7,8,9]]],'名称':[[100,101] ,[202,203]]} 其中 100 是 [1] 的名称，101 是 [2,3,[4]] 的名称，202 是 [5,6] 的名称，203 是[7,8,9] 的名称

更清楚:

`{'data':[[ [1],[2,3,[4]] ],[ [5,6],[7,8,9]]]
             |      |           |      |
'name':  [[ 100,   101    ],[  202,   203  ]]

，一旦我将数据展平并变为:[1,2,3,4,5,6,7,8,9] 相应的名称数组仍然是 [100,101,202,203]，这意味着不匹配，我希望它们匹配，所以当我展平嵌套数组时，我可以获得内部元素的相同名称，例如 get [1,2,3,4,5,6,7,8,9] 和 [100.0,101.0,101.1,101.2,101.2,202.0,202.1,203.0,203.1,203.2] 因为 [2,3,[4]] 都是named 101，100.0 表示数组中的第一个元素，2,101.2 表示数组中的第三个元素，(不关心进一步嵌套表示 [4] 仍然是 101.2 但不是 101.20，并且 [ [4]] 也是 101.2 但不是 101.200，当然，如果你是魔术师，我希望我能有这种很酷的名字风格，但我认为它对于一个问题来说已经足够复杂了)，因此，名字数组也会正确压平。

这是一种头脑 Storm ..感谢您的帮助..

### 我已经重写了这个问题，最后一天在@schlezzz15 的帮助下我在我的原始数据中发现了一些错误，非常感谢，可惜数据太大而且很难找到里面的错误，真的很抱歉

有趣的问题。

zip 的解决方案, itertools.chain , itertools.cycle和 compiler.ast.flatten

from compiler.ast import flatten
from itertools import chain,cycle
d = {'data':[[ [1],[2,3,[4]] ],[ [5,6],[7,8,9]]],       
     'name':  [[ 100,   101    ],[  202,   203  ]]}

data,name = chain(*d["data"]),list(chain(*d["name"]))
data = [flatten(sublist)for sublist in data ]

print name
# >>> [100, 101, 202, 203]
print data
# >>> [[1], [2, 3, 4], [5, 6], [7, 8, 9]]

aligned = zip(name,data)
print aligned
# >>> [(100, [1]), (101, [2, 3, 4]), (202, [5, 6]), (203, [7, 8, 9])]

result = [zip(cycle([n]),da) for n,da in aligned]
print result
# >>> [[(100, 1)], [(101, 2), (101, 3), (101, 4)], [(202, 5), (202, 6)], [(203, 7), (203, 8), (203, 9)]]

flattened_result = list(chain(*result))
print flattened_result
# >>> [(100, 1), (101, 2), (101, 3), (101, 4), (202, 5), (202, 6), (203, 7), (203, 8), (203, 9)]


string_result = [str(item[0])+"."+str(item[1]-1) for item in flattened_result]
print string_result
# >>> ['100.0', '101.1', '101.2', '101.3', '202.4', '202.5', '203.6', '203.7', '203.8']


# I do not recommend the below version, only on OP's request.
d = {'data':[[ [1],[2,3,[4]] ],[ [5,6],[7,8,9]]],       
     'name':  [[ 100,   101    ],[  202,   203  ]]}
all_in_one =[str(item[0])+"."+str(item[1]-1) for item in chain(*[zip(cycle([n]),da) for n,da in zip((chain(*d["name"])),(flatten(sublist)for sublist in chain(*d["data"])))])]
print all_in_one == string_result
# >>> True

我不确定您想要哪种输出格式，因此我包含了所有中间结果。你应该很容易得到你想要的。如果您指定所需的输出，我将修改我的解决方案。
