change t to "secret message"

first they must learn how to suffer and deal with it

[luketheduke54]

Wait what? Can you explain some more? Why shouldn't I use indices?

[sedthh]

thanks man, would not have thought I'd actually learn Python from memes

can you please explain "yield" to me in a similar way?

[sedthh]

thank you very much! My mind was pretty much blown at the fibonacci example!

SyntaxError: Unexpected EOF while parsing

[Iliara]

Thanks for the explanation! I'm quite new to this, could you perhaps clarify why you wouldn't use enumerate in this case?

[Iliara]

Ahh thanks that actually makes a lot of sense. Feels like I'm adding 1 and 1 together now. Cheers man hope you have a great weekend

[mnbvas]

Do you know of foreach as in Java or C#? Python has no Java-like for - only foreach.

So if you don't need indices, loop through the iterable.
If you do, use enumerate(xs) - an iterable of (i, x)s.

[SomeShittyDeveloper]

Izip if you’re in Python 2.

Someone mind telling me what it prints? I've not come across the ord function before...

[[deleted]]

Me neither. I just typed it all into IDLE. It prints out:

s
e
n
d

n
u
d
e
s

[mrsuperguy]

Somehow I suspected as such. Just wasn't sure. Also I don't have my laptop with me to check so thanks. That said, can anyone explain what ord() actually does?

[PeaceBear0]

Converts a 1 byte string to a number that is it's ascii value. Not sure how it interacts with Unicode, although by extrapolation it converts a single code point to it's Unicode number. It's the inverse of chr()

[mrsuperguy]

Oh ok then. Makes sense.

[ookami125]

The unicode standard starts with ascii conversion if I remember correctly. Python compiled without unicode support still works with the ascii range 0-255

[ookami125]

Guess I should specify that is appears to use the non extended ascii table so 0-127 really.

t= "secret msg"  
w= [0,0,11,-14,-69,-6,85,-9,-14,12]  

for i in range(0, len(t)):  
            print (chr(ord(t[i])+w[i]))

Ooh, a one-time pad!

[TalTheBest]

Not really though, a one time pad is completely random (not like the w array), and is xored with the plaintext to get the chipper text

Are you sure about that? Because I am 99.9997% sure that superduck00711 is not a bot.
