if you want to show off, and use a more pythonic interface, you can do
it with a lot fewer lines. here's one example:
def parseline(line, *types):
result = [c(x) for (x, c) in zip(line.split(), types) if c] or [None]
return len(result) != 1 and result or result[0]
text = "H 0.000 0.000 0.000"
print parseline(text, str, float, float, float)
print parseline(text, None, float, float, float)
print parseline(text, None, float)
etc. and since you know how many items you'll get back from the
function, you might as well go for the one-liner version, and do
the unpacking on the way out:
def parseline(line, *types):
return [c(x) for (x, c) in zip(line.split(), types) if c] or [None]
text = "H 0.000 0.000 0.000"
[tag, value] = parseline(text, str, float)
[value] = parseline(text, None, float)
