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:
try py.list('x','y',1) catch e e.message if(isa(e,'matlab.exception.PyException')) e.ExceptionObject end end
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
