Handle Python Exceptions

MATLAB® catches exceptions thrown by Python® and converts them into a matlab.exception.PyException object, which is derived from the MException class. For example:

catch e
ans =

Python Error: TypeError: list() takes at most 1 argument (3 given)

ans = 

  Python tuple with no properties.

    (<type 'exceptions.TypeError'>, TypeError('list() takes at most 1 argument (3 given)',), None)

If MATLAB displays an error message of the following format, refer to your Python documentation for more information.

Python Error: Python class: message
