Returns the parameter definition as a Python command which can be used within a Python Processing script.
The outputType argument specifies the desired output format for the Python string, i.e. the intended end use of the generated Python code.

Sets the maximum value acceptable by the parameter.
An invalid QDateTime value indicates no maximum value.

Sets the minimum value acceptable by the parameter.
An invalid QDateTime value indicates no minimum value.
