new user python on hp prime g2, casio cg50

There are several things going on there.

) The use of "y = sqrx(sys.argv[0])" rather than a standard python input statement.
I was surprised (positively) that an input form line was presented.

) The intended square was presented on the terminal screen rather instead of being
returned as a return value.

) If the python environment accepts the C-style input maybe there is a
C-style output statement.
