The right way to Save a Python Dictionary to a File in Python

If you must save a Python Dictionary object sort to a file utilizing Python, then you are able to do one of many following:

Choice 1 – Utilizing `pickle` module#

import pickle

my_dict = { 'Bob': 31, 'Jane': 50, 'Harry': 13, 'Steve': 23}

with open("dictionaryFile.pkl", "wb") as tf:
    pickle.dump(my_dict,tf)

Then you may load the pickle file again as follows:

import pickle

with open("dictionaryFile.pkl", "wb") as tf:
    new_dict = pickle.load(tf)

print(new_dict)

import numpy as np

my_dict = { 'Bob': 31, 'Jane': 50, 'Harry': 13, 'Steve': 23}
np.save('dictionaryFile.npy', my_dict)

Then you may load the file again as follows:

import numpy as np

new_dict = np.load('dictionaryFile.npy', allow_pickle='TRUE')
print(new_dict.merchandise())

import json

my_dict = { 'Bob': 31, 'Jane': 50, 'Harry': 13, 'Steve': 23}

tf = open("dictionaryFile.json", "w")
json.dump(my_dict,tf)
tf.shut()

Then you may load the file again as follows:

import json

tf = open("dictionaryFile.json", "r")
new_dict = json.load(tf)
print(new_dict)
