save-return 0.1.0

Save the return value of the decorated function to a versioned pickle file

save-return

Save the return value of the decorated function to a versioned pickle file.

Save

import save_return

@save_return.save('value_of_pi')
def calc_pi():
    return 4

pi = calc_pi()

This will pickle.save pi to ./autosave/value_of_pi/yyyymmdd_HHMMSS_MS_00000.pkl

If used inside a Jupyter notebook named x.ipynb, it will instead save to ./x.ipynb.autosave/value_of_pi/yyyymmdd_HHMMSS_MS_00000.pkl

Use @save_return.save(..., save_dir="some-dir") to customize the save location.

pi = calc_pi()

Call it again will save pi to ./autosave/value_of_pi/yyyymmdd_HHMMSS_MS_00001.pkl

Load

The load function is just a wrapper around pickle:

pi = save_return.load('./autosave/value_of_pi/yyyymmdd_HHMMSS_MS_00000.pkl')
