Half-term report

Pupil: Myra Champaign

Teahcer: Mrs. Chak

Form: 3A

Myra continues to excel across all subject areas and shows remarkable promise in Crypto, Mathematics and Logic. As always, she has achieved outstanding marks in class, though her scores did suffer in the run-up to the PCAG Championships. I sometimes worry that Myra is rather isolated from her classmates, and there have been occasions where she has been the victim of mean-spirited pranks. Unfortunately, she may need to get accustomed to this kind of envy as her career progresses.

Not sure if this is only on my card or not, but it appears to me that there is a slight difference in color in the grid from the line next to "Fuschia" (in the word bank) up. Do other people see this too (it's easier to notice if you hold the card slightly away from your face)?

Here's a Python script I wrote to solve this guy. I figured it would be easier on my eyes, and a much better way to start learning Python than Hello World.

Basically, the program loads in letters and their braille representations from a file, then loads in the card data from another file. It starts at one of six starting places and goes through the whole grid by row and column looking for braille patterns. The result is a series of six grids of letters from which you can easily find the color names by hand.

Probably not the greatest script ever, but I'm pretty happy with it since it is my first Python program Very Happy

Main script (since I can't attach it):
Code:
import sys

#-----------------------------------------------------------

def printData (pData):
    # Pretty printing functions

    for rowIndex in range(0, len(pData)):
        for colIndex in range(0, len(pData[0])):
            sys.stdout.write(pData[rowIndex][colIndex])               
        print

    return 0

def GenerateLetters(pStartX, pStartY):
    # Generate a letter grid from a particular start location
   
    aOutput = [ ]
    for rowIndex in range(pStartX, len(aData), 3):

        if (rowIndex+1 < len(aData)-1 and rowIndex+2 < len(aData)):
            aOutputRow = [ ]
           
            for colIndex in range (pStartY, len(aData[0]), 2):

                if (colIndex+1 < len(aData[0])):
                    strKey = ""
                    strKey += aData[rowIndex][colIndex]
                    strKey += aData[rowIndex][colIndex+1]
                    strKey += aData[rowIndex+1][colIndex]
                    strKey += aData[rowIndex+1][colIndex+1]
                    strKey += aData[rowIndex+2][colIndex]
                    strKey += aData[rowIndex+2][colIndex+1]

                    try:
                        aOutputRow.append("%s" % (dictBraille[strKey]))
                    except KeyError:
                        aOutputRow.append(".")
               
            aOutput.append(aOutputRow)

    print "Start location (%s,%s):" % (pStartX,pStartY)
    print
    printData(aOutput)
    print "-"*30
    print
   
    return 0

#-----------------------------------------------------------
# Main program
#-----------------------------------------------------------
fileBraille = open('braile.txt','r')
dictBraille = { }

for curFileRow in fileBraille.readlines( ):
    curFileRow = curFileRow.replace('\n','')
    curFileRowSplit = curFileRow.split(',')
   
    dictBraille[curFileRowSplit[1]] = curFileRowSplit[0]

# Open the file of braille letters and read into an array
fileData = open('data.txt','r')
aData = [ ]

for curFileRow in fileData.readlines( ):
    curFileRow = curFileRow.replace('\n','')

    aDataRow = [ ]
    for curChar in curFileRow:
        curChar = curChar.replace('.','*')
        curChar = curChar.replace(' ','.')
        aDataRow.append(curChar)

    aData.append(aDataRow)

an easier way, no computing involved

I found it easier to look for letters and find the colours from them. The ones I used were
Spoiler (Rollover to View):
V P L G R E W L

and that narrowed it down to unused spaces, given you'll probably miss the odd one. I found this much easier than looking for whole words.
Also, less of a giveaway if you want to look yourself,
Spoiler (Rollover to View):
All of the colours are hidden in the same directions as the two clues, which made looking a whole lot simpler than if back to front or diagonals had been used.[spoiler]

I started off by looking for letters.
Looked for C and got most of those, then realised that this process was probably going to take too long.

So I did it by working out the six grids.
It's a lot quicker than you think, especially after the first two girds when you know most of the characters.

Anyway, I'm going to post them here in case there are hidden messages in the other letters:

Grid 1:
xo (I've used this notation to mean that the top
oo left hand corner of the grid is where the
oo x is in the 6 top-left dots of the main grid)

Spoiler (Rollover to View):

(note the spoiler is to a link of a picture)

Grid 2:
ox
oo
oo

Spoiler (Rollover to View):

Grid 3:
oo
xo
oo

Spoiler (Rollover to View):

Grid 4:
oo
ox
oo

Spoiler (Rollover to View):

Grid 5:
oo
oo
xo

Spoiler (Rollover to View):
(Okay, can't find the piece of paper atm, will edit when I've tidied some of the mess off my desk.)


Grid 6:
oo
oo
ox

Spoiler (Rollover to View):
http://i5.photobucket.com/albums/y158/pineapplejelly/Perplex%20City/S2198Grid6.jpg


Please note there are mistakes in these, as I ended up with four missing colours, not two.

(Got it right on first guess anyway though Very Happy )

Corrections are welcome and encouraged.
