# 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: dump()

# dump()

import pickle

data1 = {'a': [1, 2.0, 3, 4+6j],
         'b': ('string', u'Unicode string'),
         'c': None}
               
selfref_list = [1, 2, 3]
selfref_list.append(selfref_list)
               
output = open('data.pkl', 'wb')
               
# Pickle dictionnary using protocol 0.
pickle.dump(data1, output)
               
# Pickle the list using the highest protocol available.
pickle.dump(selfref_list, output, -1)
               
output.close()
