Split a Dict or List into Chunks in Python

Sometimes, it is desirable to split a large python iterable into smaller iterables. I have developed a small module for Stockr which can be used to help with this common task.

Supported iterable types:

• Lists
• Most Basic Generators
• Dictionaries
• Django QuerySets

Module: List-Splitter

Usage:

import list_splitter

inp_dict = {
  'a': 1,
  'b': 2,
  'c': 3,
  'd': 4,
  'e': 5,
  'f': 6
}

inp_list = [
  1,
  2,
  3,
  4,
  5,
  6
]

"""
Prints:

[
  {'a': 1, 'b': 2, 'c': 3},
  {'d': 4, 'e': 5, 'f': 6}
]
"""
print(list(list_splitter.n_chunks(inp_dict, 2)))

"""
Prints:

[
  [1, 2, 3],
  [4, 5, 6]
]
"""
print(list(list_splitter.n_chunks(inp_list, 2)))

"""
Prints:

[
  {'a': 1, 'c': 3},
  {'b': 2, 'e': 5},
  {'d': 4, 'f': 6}
]
"""
print(list(list_splitter.chunks_of_n(inp_dict, 2)))

"""
Prints:

[
  [1, 2],
  [3, 4],
  [5, 6]
]
"""
print(list(list_splitter.chunks_of_n(inp_list, 2)))

"""
Prints:

[
  [{'a': 1}, {'c': 3}],
  [{'b': 2}, {'e': 5}],
  [{'d': 4}, {'f': 6}]
]
"""
print(list(list_splitter.chunks_matrix(inp_dict, 1, 2)))

"""
Prints:

[
  [[1], [2]],
  [[3], [4]],
  [[5], [6]]
]
"""
print(list(list_splitter.chunks_matrix(inp_list, 1, 2)))

"""
Prints:

[
  [{'a': 1, 'c': 3}],
  [{'b': 2, 'e': 5}],
  [{'d': 4, 'f': 6}]
]
"""
print(list(list_splitter.chunks_matrix(inp_dict, 2, 1)))

"""
Prints:

[
  [[1, 2]],
  [[3, 4]],
  [[5, 6]]
]
"""
print(list(list_splitter.chunks_matrix(inp_list, 2, 1)))
