What is a Pkl?

Pkls, short for 'Pickles,' are often referred to in the context of Python programming as files that use the pickle module to serialize and deserialize Python objects. This means that Pkl files store Python objects in a binary format that can be saved to disk and later restored. In some regions, 'Pkl' may also refer to specific job roles or technical positions, so it's important to confirm the context. In data science and machine learning, Pkl files are commonly used to save trained models or datasets for later use. Always ensure that Pkl files are from trusted sources, as loading them can execute arbitrary code.
