This is the v1.25.0 version of the MicroPython documentation. The latest development version of this page may be more current.

marshal – Python object serialization

This module implements a subset of the corresponding CPython module, as described below. For more information, refer to the original CPython documentation: marshal.

This module implements conversion between Python objects and a binary format. The format is specific to MicroPython but does not depend on the machine architecture, so the data can be transferred and used on a different MicroPython instance, as long as the version of the binary data matches (it’s currently versioned as the mpy file version, see MicroPython .mpy files).

Functions

marshal.dumps(value, /)

Convert the given value to binary format and return a corresponding bytes object.

Currently, code objects are the only supported values that can be converted.

marshal.loads(data, /)

Convert the given bytes-like data to its corresponding Python object, and return it.
