Too Long; Didn't Read
If you are using <a href="https://hackernoon.com/tagged/python" target="_blank">Python</a>, especially for machine learning, you should be somewhat familiar with the standard library module named <a href="https://docs.python.org/3.6/library/pickle.html" target="_blank">pickle</a>. It is used for Python object serialization and comes very handy in wide range of applications. Some objects that you might want to serialize: a trained scikit-learn model, a Pandas DataFrame that you got after a lengthy join of several tables; basically any Python object that consists of heterogeneous data that you might want to quickly load in a new environment in the future (for homogeneous data, like neural network weights or training data tensor, it’s better to use a more suitable format like <a href="http://www.h5py.org/" target="_blank">HDF5</a>).
