Exception thrown when no arguments given

Describe the bug
When I run avg.py with no arguments, it crashes:

~/code/nswi177-avg% (master) ./avg.py
Traceback (most recent call last):
  File "/home/d/code/nswi177-avg/./avg.py", line 11, in <module>
    main()
  File "/home/d/code/nswi177-avg/./avg.py", line 7, in main
    avg = sum(values) / len(values)
          ~~~~~~~~~~~~^~~~~~~~~~~~~
ZeroDivisionError: division by zero

See? Told you!
