Alright, I'm sure I've made this more complicated than it should be, but packaging/unpacking it confusing to me, so hang tight. Prior to this version of code, I attempted something like:
for num in args:
total *= num
But that didn't seem to go over well. I'm not quite sure where the breakdown is occurring. If I could see the console output I think I'd know, but I am unsure. Here is what I think:
- The input isn't being properly unpackaged and therefore, a
for
orwhile
loop is irrelevant - The argument cannot simply be multiplied because it's not an
int
- I've completely missed the point and there's something else
Would love some thoughts on where I went wrong here.
def multiply(*args)
total = 1
i = 0
while i <= len(args):
total *= args[i]
i += 1
return total

- the "def" line needs a colon at the end
- the highest index is less than the length, instead of "<=" use "<"
And for this strategy, you didn't need a slice. The hint would apply to a different strategy where you started with the first item (instead of 1) and then multiplied by the items in a slice with everything else in it.
