Best way to define multidimensional dictionaries in python? [duplicate]

Answer 1

You can create a multidimensional dictionary of any type like this:

from collections import defaultdict
from collections import Counter

def multi_dimensions(n, type):
  """ Creates an n-dimension dictionary where the n-th dimension is of type 'type'
  """  
  if n<=1:
    return type()
  return defaultdict(lambda:multi_dimensions(n-1, type))

>>> m = multi_dimensions(5, Counter)
>>> m['d1']['d2']['d3']['d4']
Counter()
