The <add> block is equivalent to the « + » operator inPython, it allows you to either :
•add two numbers
•concatenate two elements de (strings, list, tuple)
See the Python documentation for more details.
•« a » : The default value is 0 (type: int)
•« b » : The default value is 0 (type: int)
•« out » : = a + b. Its type depends on the types of the inputs
If one of the inputs is of type int or float, the other input must also be of type int or float.
If one of the inputs is of type “string,” the other input must be of the same type
If one of the inputs is of type “list,” the other input must be of the same type
If one of the inputs is of type “tuple,” the other input must be of the same type
