Dataway Python expressions are encapsulated based on Python 3. Their features are also tailored based on Python, and you must define a valid entry function
dw_process(msg). Therefore, all Dataway expressions have a returned value after being executed normally, but Python scripts don't necessarily have a specific returned value.
Currently, almost all core iPaaS components can calculate the value of expressions. Dataway plays a key role in implementing the dynamic value calculation capabilities of iPaaS.
By default, Dataway supports only the following built-in modules:
Generally, such modules are enough for Dataway scripts. If you do need to use more third-party modules, please submit a ticket to request support for an additional third-party module.
