Confused on what a challenge is asking?

[Project hash brown]

Thank you, i wasn't counting the 2 when i went back two places, i jumped straight back to the 3 again

What is a 8411 ???
I don't want any hint or solution, but the challenge name is "Like a 8411" and i have no idea about what a 8411 could be

Found it .... had to think outside the box

In the "Didactic Scrambled Egg Cipher Pre-Warmup Challenge"-challenge does " for (int eggs = {each 3-byte tuple in plaintext}) " mean that i should consider 000102, 030405 ,060708 or 000102,010203, 020304 ... for the plaintext 00010203040506070809 in hex?

It means your first guess, i.e. 000102, 030405, ...

I have absolutely no idea what the challenge "Anybody Out There?" is asking for

[gfoot]

There should be no doubt about the right answer for Anybody Out There - if you work out what the numbers mean then it will be obvious.

Hi everyone. I've been trying to debug the following *Python26* code for the challenge Valuation for about 2 days now, without succession:

Code: Select all

main = [1,2,3,'x','x',4,5,6]
counter = 0
lenght = len(main)
total = 0
while counter < lenght:
    if main[counter] == "'x'":
        main.remove(counter)
        counter = counter - 2
    else:
        total = total + main[counter]
        counter = counter + 1
if counter == lenght:
    print total

Am I making the right approach with the "'x'", or should I just store x = 0 at the start and take 'these' off the ones on the main list?
Also, on:

Code: Select all

    else:
        total = total + main[counter]

It gives me an error:

TypeError: unsupported operand type(s) for +: 'int' and 'str'

What I do understand of this error is that I cannot add a string to a total sum, but I have no idea for to make it work even with the int() operator/variable. Trying to wrap the line, a part of the line, or even only a word in the line doesn't seem to do the trick. I just can't seem to be able to change a string into int and vice versa.
Should I instead define the int() and str() already in the list to make it work or does someone have a brighter idea?

I just can't seem to understand how I'm able to fail at something as simple as this. Might be that I'm new to the language anyways but...

Thanks in advance!

I'm using Python 3.1, but I think the way you are using remove is wrong. I suggest you take a look into the documentation for the correct use of remove.

And why do you use an if-statement at the end?

to print out the total only when the counter is the same as lengTH (omglol typo on teh code) of the original main list - aka when it meets the end of the list.

Try to understand the following interactive python session.
After that review your code again.
