There's no need to look up sys.argv[1] twice, nor any need to write
main(x) in both blocks. You can do each once only:
try:
# Always use the minimum code needed inside a try block.
x = sys.argv[1]
except IndexError:
x = "some default value"
main(x)
Here's yet another way:
args = sys.argv + ["some default value"]
main(args[1])
