How to split dictionary into multiple dictionaries fast

Question

I have found a solution but it is really slow:

def chunks(self,data, SIZE=10000):
    for i in xrange(0, len(data), SIZE):
        yield dict(data.items()[i:         


        

Answer 1

import numpy as np
chunk_size = 3
chunked_data = [[k, v] for k, v in d.items()]
chunked_data = np.array_split(chunked_data, chunk_size)

Afterwards you have ndarray which is iterable like this:

for chunk in chunked_data:
    for key, value in chunk:
        print(key)
        print(value)

Which could be re-assigned to a list of dicts using a simple for loop.
