I'm guessing it's the boost python equivalent of the Python code:
>>> "%s is bigger than %s" % (NAME,name)
The c++ statement is doing the same, via operator overloading. If we look at
the statement bit-by-bit:
object msg="%s is bigger than %s" % make_tuple(NAME,name);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Creating a boost python object called 'msg' and assign the string "%s is
bigger than %s" to it.
object msg="%s is bigger than %s" % make_tuple(NAME,name);
^^^^
The '%' operator is overloaded by boost python to work the same as in
python.
object msg="%s is bigger than %s" % make_tuple(NAME,name);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Create a tuple of NAME,name and pass that to the '%' operator.
Cheers.
