The block <print> is the equivalent of the print function in Python:
Refer to the Python documentation for more detail.
•« text » : This is the text passed as parameter to Python’s print function. The default value is « ABCD » (type str)
•« out » : only allows the <print> block to be executed
The input is of type : str
The output is not explicitly typed, its type is therefore the default type, which is None
Used essentially for debugging.
