repickle 0.1.0

Extended pickling support for Python object

Repickle

Repickle makes it possible to serialize Python constructs not supported by the default pickle module from the Python standard library. Repickle just extends cloudpickle and add support for load and dump to files.

Installation

The latest release of repickle is available from pypi:

pip install repickle

Examples

Pickling a lambda expression:

>>> import repickle
>>> squared = lambda x: x ** 2
>>> repickle.dump_to_file(squared, "pickled_lambda.pkl")

>>> new_squared = repickle.load_from_file("pickled_lambda.pkl")
>>> new_squared(2)
4

Pickling a function interactively defined in a Python shell session (in the __main__ module):

>>> CONSTANT = 42
>>> def my_function(data: int) -> int:
...     return data + CONSTANT
...
>>> import repickle
>>> repickle.dump_to_file(my_function, "pickled_lambda.pkl")
>>> depickled_function = repickle.load_from_file("pickled_lambda.pkl")
>>> depickled_function(43)
