In my personal experience, I suggest using JSON if:
- You want a human-readable file,
- A file type that is compatible across multiple technologies without very much implementation overhead.
- An easily editable file (as it can simply be a text file).
I would suggest using Pickle if:
- The majority of the project will be written in python.
- The dictionary is likely to become very large/complex or rolled into a larger class.
- A non-human readable file is required.
- A file that is difficult to edit without prior knowledge of its construction.
Based on the situation you touch upon in your question, JSON would be the more beneficial choice.

# example code here import json d = {1: 'a', 2: 'b', 3: 'c'} with open('C:\temp.txt', 'w') as file: json.dump(d, file) with open('C:\temp.txt', 'r') as file: new_d = json.load(file) >>> new_d {u'1': u'a', u'3': u'c', u'2': u'b'} |

# python built-in package # don't need to install import pickle # Use mode='wb',Write and Serialize into Binary with open(file='./Data/data.pkl', mode='wb') as f: pickle.dump(obj=data, file=f) # Use mode='rb',Read and Deserial from Binary and read with open(file='./Data/data.pkl', mode='rb') as f: data_restore = pickle.load(f) |
