# Because of the first line of this script, we can run it at the
# command prompt $ typing ./hello_python.py.
# Two potential issues:
# (1) Do "which python" on your system to check whether you need to
#     adjust the location of the Python interpreter.
# (2) With "chmod +x hello_python.py" the file is an executable.
