python - How to check if an argument from commandline has been set?

I can call my script like this:

python D:myscript.py 60

And in the script I can do:

arg = sys.argv[1]
foo(arg)

But how could I test if the argument has been entered in the command line call? I need to do something like this:

if isset(sys.argv[1]):
    foo(sys.argv[1])
else:
    print "You must set argument!!!"
