How Can I Save and Load Python Objects Using Pickle?

Saving Python Objects Using Pickle

Pickle is a Python library that enables you to serialize objects and save them to a file, ensuring that they can be reconstructed later.

Example for Saving a Dictionary

To save a dictionary to a file using pickle, follow these steps:

1. Import the pickle library: import pickle
2. Open the output file in write binary mode: with open('filename.pickle', 'wb') as handle:
3. Dump the dictionary to the file: pickle.dump(a, handle, protocol=pickle.HIGHEST_PROTOCOL)

You can replace a with any Python object, such as a list, tuple, or custom class instance.

Loading Pickled Objects

To load a pickled object from a file, follow these steps:

1. Open the input file in read binary mode: with open('filename.pickle', 'rb') as handle:
2. Load the object: b = pickle.load(handle)

You can access the loaded object through the variable b by using the same code that was used to create the object.
