python pickle module code 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: 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 3: 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 4: pickle python

1 # Load the dictionary back from the pickle file.
   2 import pickle
   3 
   4 favorite_color = pickle.load( open( "save.p", "rb" ) )
   5 # favorite_color is now { "lion": "yellow", "kitty": "red" }
