If you need to save a Python Dictionary object type to a file using Python, then you can do one of the following:
Option 1 – Using 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 can load the pickle file back as follows:
import pickle
with open("dictionaryFile.pkl", "wb") as tf:
new_dict = pickle.load(tf)
print(new_dict)
Option 2 – Using numpy
import numpy as np
my_dict = { 'Bob': 31, 'Jane': 50, 'Harry': 13, 'Steve': 23}
np.save('dictionaryFile.npy', my_dict)
Then you can load the file back as follows:
import numpy as np
new_dict = np.load('dictionaryFile.npy', allow_pickle='TRUE')
print(new_dict.item())
Option 3 – Using a json dump
import json
my_dict = { 'Bob': 31, 'Jane': 50, 'Harry': 13, 'Steve': 23}
tf = open("dictionaryFile.json", "w")
json.dump(my_dict,tf)
tf.close()
Then you can load the file back as follows:
import json
tf = open("dictionaryFile.json", "r")
new_dict = json.load(tf)
print(new_dict)
