These examples also have a reasonable implementation using list.pop(),
albeit one that requires more typing. On the plus side, it does not violate
DRY and is explicit about the error cases.
args = input.split()
try:
cmd = input.pop(0)
except IndexError:
cmd = ''

try:
arg1 = rest.pop(0)
arg2 = rest.pop(0)
except IndexError:
raise TypeError("foo() takes at least 2 arguments")
