Is there a way to turn binary into a QR code programmatically?

Question

I have the following:

1 1 1 1 1 1 1   1   1   1 1   1     1 1 1 1 1 1 1 
1           1     1 1 1 1 1     1   1           1
1   1 1 1   1   1 1 1         1     1   1 1 1   1 
1   1 1 1   1   1 1 1   1   1 1     1   1 1 1   1 
1   1 1 1   1   1     1 1   1 1 1   1   1 1 1   1 
1           1       1 1   1     1   1           1 
1 1 1 1 1 1 1   1   1   1   1   1   1 1 1 1 1 1 1 
                    1   1     1 1                 
1 1 1 1     1   1   1 1 1 1   1 1 1     1 1 1   1 
    1         1     1   1 1 1   1     1   1       
1 1   1 1 1 1     1 1 1 1 1     1         1       
    1 1 1     1   1 1           1 1       1 1 1   
    1 1 1 1 1 1   1 1   1   1     1 1 1 1   1 1   
      1   1   1 1 1   1 1   1 1 1   1 1 1   1 1 1 
  1   1     1 1 1     1   1           1       1   
1   1 1 1 1     1   1 1     1         1       1 1 
    1   1 1 1 1 1   1   1   1   1 1 1 1 1   1 1   
                1   1       1 1 1       1 1 1   1 
1 1 1 1 1 1 1     1 1     1 1   1   1   1     1 1 
1           1     1   1   1 1 1 1       1         
1   1 1 1   1     1       1 1   1 1 1 1 1         
1   1 1 1   1   1 1 1             1 1   1 1   1 1 
1   1 1 1   1   1 1         1   1   1 1 1     1   
1           1   1     1 1 1 1     1       1 1     
1 1 1 1 1 1 1   1   1 1             1     1 1 1 1

and it won't scan on a QR code reader. Is there any way I can change this into an actual QR code so that it is scannable?

In what format? Also, it might work better if you used some other symbol then "1", like "#" or something more "filling". — CrazyCasta

Since it appears you already know which squares to make black and which not, you could just use pillow to generate an image. You'll need to use ImageDraw and Image. What you need to do is something like:

from PIL import Image, ImageDraw
im = Image.new('1', (width, height), color=1) # Background white
draw = ImageDraw.Draw(im)
draw.point((x, y), 0) # Draw black

I actually ended up turning the background of my text editor white, replacing all the 1 characters with two █ characters ██, taking a screenshot of it, and then scaling down the image so that it wasn't so spread out.

Just thought I'd add that in for completeness.
