HI im trying to make a card dealer, but this code doesent work correctly. It
deasl cards, but the cards to repeat. when i type in 52 ten i might get 3 the

read it. I could use online translators for the line, but since i have 255

There is this class file, it has its functions and variables. Now im greating my program, that uses the funcions from the class. BUt there are some functions missing from the class.

Image consists of pixels. Each pixel has its RGBA values. In python whidout any extra downloadable modules, is there a way to get those values.

Re: Odd-length string
I fixed this problem but encountered new problem. Problem was that some parts
that came throug my decryption were 00 or 0 the first symbol so the program
didnt show them.
NEw problem is : Traceback (most recent call last):
File "C:\Users\Marko\Desktop\hacker.org\XOR cypher.py", line 35, in
print("Key-" + str(võti) + ": " + str("".join(tulemus2)))
TypeError: sequence item 0: expected str instance, bytes found
If i take away the join command i get this: Key-: [b'u', b'o',
b'\x00', b'\x1d', b' ', b'|', b'N', b'\x0f', b'9', b'j', b'K', b'J', b'&',
b'#', b'A', b'K', b'5', b'k', b'_', b'\x1e', b',', b'j', b'\x0c', b'\x08',
b'i', b'(', b'\x06', b'\\', b'r', b'3', b'\x1f', b'V', b's', b'9', b'\x1d']
the Key- is the key im using to decrypt the code. everything else is
generated byt the decrytion process and the unhexlify command. So my guess is,
the join command cant handle the b"u" type of format. how can i get rid of the
b.
Or does anyone have a better idea how to translate HEX into ASCII and sort out
the lines that make sense

Because i was told so, cause the subject change so it cant be under there

This is the code i came up with:
from teisendaja import *
from operator import *
import binascii
teisendus = teisendus()
kood = input("Kood: ")
key = input("Võti: ")
chunksize = 2
vastus = [teisendus.teisendus3(16,2,kood[i: (i + chunksize)]) for i in range(0,
len(kood),chunksize)]
vastus = ["0"*(8-len(x)) + x for x in vastus]
#key = teisendus.teisendus3(10,2,int(key))
getBin = lambda x, n: x >= 0 and str(bin(x))[2:].zfill(n) or "-" +
str(bin(x))[3:].zfill(n)
def dekrüpteeria(vastus, key):
XOR = []
tulemus = []
for i in range(len(vastus)):
for j in range(8):
XOR.append(str(ixor(int(vastus[i][j]), int(key[j]
tulemus.append("".join(XOR))
key = "".join(XOR)
XOR = []
return tulemus
tulemus2= []
if key == "":
for i in range(256):
võti = getBin(i,8)
tulemus = [teisendus.teisendus3(2,16,i) for i in dekrüpteeria(vastus,
võti)]
tulemus = ["0"*(2-len(x)) + x for x in tulemus]
# for j in range(len(tulemus)):
tulemus2.append(binascii.unhexlify("".join(tulemus)))
print("Key-" + str(võti) + ": " + str(tulemus2))
tulemus2 = []
#tulemus = [teisendus.teisendus3(2,16,i) for i in dekrüpteeria(vastus, key)]
#print(":".join(tulemus))
#751a6f1d3d5c3241365321016c05620a7e5e34413246660461412e5a2e412c49254a24
Although this is quite ugly atm. But it serves me well, until i reach the
unhexlify part. The number and lette r string at the wery end is the mesage im
trying to decypher.

OK so I did a took time of and read the pykkar code through. abd I found that
there is a third class i have to implement.
This Is the pykkar sourcecode
# coding=UTF-8
"""
Intro and usage
===
Pykkar is a virtual robot living in a virtual world. It can step, turn 90
degrees right,
paint floor tiles, take and put down traffic cones and push boxes. It can detect
whether there is a wall or other obstacle ahead or whether it's standing on a
painted
tile. It can be commanded by Python code (either procedural or OOP style)
Pykkar's world can be created by a call to ``create_world`` (when using
procedural style)
or by instantiating class ``World`` (OOP style). Both take single argument,
which is
a string representation of the world. Lines in the string represent the rows in
the world
map. Each character represents one tile. Meaning of characters:
#wall
plain floor
.painted floor
bbox on plain floor
Bbox on painted floor
^ > v < pykkar on plain floor without cone
(caret, greater-than, lowercase v, less-than)
N E S W pykkar on painted floor without cone
1 2 3 4 5 6 7 8 9cone stack on plain floor
Csingle cone on painted floor
Sample:
create_world('''
#> #
# 3#
''')
this creates a world where 2x2 floor are is padded with walls. Pykkar is in
north-west
corner of the floor, looking east and in south-east corner there is a stack of
3 traffic
cones.
In procedural style, Pykkar can be commanded by calling global functions
defined in this
module (eg. ``step()``, ``right()``, etc). There are also functions for
querying the
world (``is_wall()``, ``is_box()``, etc). New compound commands can be defined
by defining
new functions in client module.
In OOP style, Pykkar is represented by a separate object of class ``Pykkar``.
In the
start of the program, client code is supposed to create new world (eg. ``w =
World(layout)``)
and a Pykkar living in that world (eg ``p = Pykkar(w)``). Commands are given by
calling
the methods of Pykkar object. New commands should be defined by subclassing
``Pykkar``.

Technical stuff
In order to reserve the main thread for executing commands (this way respective
function calls
can be written in client module's toplevel), tkinter window must run in a
different thread.
Unfortunately, tkinter runs reliably only in the main thread of the process.
For this reason the execution is divided into 2 processes: the "main" process,
which is just a shallow command proxy and the child process, which runs actual
program
logic and presents the world state in a tkinter window.
Main process (ie. user module) normally begins by creating the world (with
either
``create_world(...)`` or ``World(...)``). This spawns a child process which
creates
tkinter window representing the world. Main process then continues by executing
user-provided function/method calls, which amounts to writing respective
command strings
to child process' stdin and reading results back from child process' stdout.
Main player in child process is an object of class ``_WorldProper``. It keeps
the
data structures about world layout, responds to commands that alter the world
state and runs
a tkinter window. It reads periodically next command from stdin, acts upon it
and writes
result (may be None) to stdout.
NB! as stdout from tkinter process is parsed, you can't just print out debug
information
to sys.stdout. Use sys.stderr instead!

Unlimited canvas painting program
How to create a program similar to paint, but the difference would be that the cursor would be always in the middle and the canvas moves or the camera is always fixed on the cursor as it moves around the canvas. And the canvas should be infinite. What would be reasonable to use? In addition, i want it to draw a line whidout me having to press a button, just move the mouse. Ill try to think a better way to describe, what i want, but for now i hope this is sufficient and clear enough. -- https://mail.python.org/mailman/listinfo/python-list
Re: Unlimited canvas painting program
So, i`ll take the canvas, somekind of mouse tracker, for each mouse location il draw a dot or 2X2 square or something. Main thing i have never understood, is how can i get the backround to move. Lets say ia hve 200X200 window. In the middle of it is the cursor that draws. If i move the mouse the cursor doesent move, but the canvas moves. So if i move mouse to the left, i get a line that goes to the left. So i probably must invert the canvas movement. If mouse goes left, canvas goes right. And if possible i would like to save my piece of art aswell :D -- https://mail.python.org/mailman/listinfo/python-list
