To call Python libraries from MATLAB, you need to install a supported version of the reference implementation (CPython) for Python. MATLAB supports versions 2.7, 3.5, and 3.6. The version you install depends on the libraries you are using. For information, see Install Supported Python Implementation.
For help on the Python language, see www.python.org/doc.
For help on third-party or user-defined modules, refer to the product
documentation.
To call MATLAB functions from Python applications, see MATLAB API for Python.

MATLAB types that are not supported in Python.
MATLAB automatically converts compatible Python data to MATLAB data. For Python types that do not have compatible MATLAB types, MATLAB provides functions to convert Python data types to MATLAB types manually.
Limitations to Indexing into Python Objects
You can access data in Python container objects, like lists and dictionaries, with index values, similar to referencing an element in a MATLAB matrix. There are, however, ways to index into matrices which are not supported for these Python types.
MATLAB catches exceptions thrown by Python and
converts them into a matlab.exception.PyException object.
