Well I think it's pretty safe for me to assume its harder to pick up c++ from python than the other way around.

So. It's pretty darn simple.

[Parsely]

Python is very simple. If you've done no coding at all it's really easy, so being experienced should make it even easier.

[Orange Wizard]

Python is ludicrously easy. Hello World is just "print ('Hello, World')".

[Sheb]

Python is ludicrously easy. Hello World is just "print ('Hello, World')".

What happened to the comma? Weird data handling? :p

[EnigmaticHat]

No, it would still be there in the output.

...I'm making a guess that that the did not indicate sarcasm.

[Orange Wizard]

Sorry. Sometimes, I push the comma button when I don't need too.

Python is ludicrously easy. Hello, World is just "print ('Hello, World')".

Design logic for a program that outputs every even number 1 through 100.

Okay, that's not so hard. I think..

Code: [Select]

num counts[0]
counts[dep] = counts[dep] + 2
dep = 0
while dep < 100
     print dep, counts[dep]
     dep = dep + 2


Yabe Online Auctions requires its sellers to post items for sale for a six-week period during which the price of any unsold item drops 12 percent each week. For example, an item that costs $10.00 during the first week costs 12 percent less, or $8.80, during the second week. During the third week, the same item is 12 percent less than $8.80, or $7.74. Design an application that allows a user to input prices until an appropriate sentinel value is entered. Program output is the price of each item during each week, one through six.

Fuck.

Code: [Select]

num period1 = 1
num period2 = 2
num period3 = 3
num period4 = 4
num period5 = 5
num period6 = 6
num discount1 = 0
num discount2 = 0.12
num discount3 = 0.24
num discount4 = 0.36
num discount5 = 0.48
num discount6 = 0.60
num itemPrice = 10

counts[week] = counts[week] + 1

truePrice()
if week = period1 then
     perDrop = discount1
else
     if week = period2 then
          perDrop = discount2
     else
          if week = period3 then
               perDrop = discount3
          else
               if week = period4
                    perDrop = discount4
               else
                    if week = period5
                         perDrop = discount5
                    else
                         if week = period6
                              perDrop = discount6

Okay STOP. I should've used an array for this.. I just- Cannot complete, brain is melting.

[Putnam]

i think they want you to use for loops

[Gentlefish]

can you array out the discounts?

Excuse the C code but.

Code: [Select]

float discount_week[6];

for(float i = 1; i <= 6; i++)
{
   discount_week[i-1] = ( ( i - 1 ) * 0.12 ) )
}
That would initialize the entire week for you in an array where 0 is the first week and 5 is the final week.

Thanks Puffer, only thought to use an array after the fact, which I sort of just learned this morning what those were.

[Orange Wizard]

Don't worry, I made abominations far worse than that when I was learning how to code.

...

And the stuff I write now is far from professional, so yeah.

That's being mean.

Gunin basically implemented a manual hardcoded key-value lookup table or an array using if/elses, which is a pretty logical way to handle things if you don't know that dicts exist.

But disregarding innefficiency, it does make sense right?

if yes then
     WIN

yeah, it's fairly efficient in terms of speed (only O(N)!) and inefficient in terms of coder time (only O(N)!), but the logic itself is sound
