silly thing to render QR codes with unicode block characters

blockqr.py

!#/usr/bin/python3
import pyqrcode
#first create a code, and convert it to text as a pattern of 0 and 1
code = pyqrcode.create("westbrit.ie")
text=code.text()

def blockify(block):
    #this converts a representation of a 2x2 block into a unicode character
    bricks={
    "0000":" ",
    "0001":"▗",
    "0010":"▖",
    "0011":"▄",
    "0100":"▘",
    "0101":"▐",
    "0110":"▞",
    "0111":"▟",
    "1000":"▘",
    "1001":"▚",
    "1010":"▌",
    "1011":"▙",
    "1100":"▀",
    "1101":"▜",
    "1110":"▛",
    "1111":"█",
    }
    return bricks[block]


#now we loop through the qr text generating bricks
result=''
lines=text.split()
#loop through two lines at a time, and for each line loop through two characters at a time
for x in range(1,len(lines),2):
  for y in range(1,len(lines[x]),2):
    #get the 2x2 block
    #print(x,y)
    #print(lines[x][y:y+2])
    #print(lines[x+1][y:y+2])
    block=lines[x][y:y+2] + lines[x+1][y:y+2] #assemble a 4 character string for each 2x2 block
    result=result+blockify(block) #add the character to our result
  result=result+"\n" #newline for each line in the QR
print(result) #output our masterpiece. It is padded all round by spaces which might eat too many characters.
