pickle python example

Example 1: pickle a dictionary

import pickle #credits to stack overflow user= blender

a = {'hello': 'world'}

with open('filename.pkl', 'wb') as handle:
    pickle.dump(a, handle, protocol=pickle.HIGHEST_PROTOCOL)

with open('filename.pkl', 'rb') as handle:
    b = pickle.load(handle)

print (a == b)

Example 2: create pickle file python

import pickle
file_name='my_file.pkl'
f = open(file_name,'wb')
pickle.dump(my_data,f)
f.close()

Example 3: pickle.load python

import pickle
# load : get the data from file
data = pickle.load(open(file_path, "rb"))
# loads : get the data from var
data = pickle.load(var)

Example 4: pickle load pickle file

pickle_in = open("dict.pickle","rb")
example_dict = pickle.load(pickle_in)

Example 5: pickle.dump python

import pickle
# dump : put the data of the object in a file
pickle.dump(obj, open(file_path, "wb"))
# dumps : return the object in bytes
data = pickle.dump(obj)

Example 6: save a file as a pickle

with open('mypickle.pickle', 'wb') as f:
    pickle.dump(some_obj, f)

# note that this will overwrite any existing file
# in the current working directory called 'mypickle.pickle'
