Even outside of numpy, a lot of Python uses functions, not methods. One good reason for this is that a function can accept a wide variety of data types as its argument; for instance, len() accepts many things, not just lists. Some things are done with methods, others with stand-alone functions. There are design choices each way. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
