Save pixel data in txt format in PIL

Question

My program is to extract the pixel from an image and to save the pixel data in the text file for analysis. My picture is a binary image that gives only 255 and 0 's

Here is the program:

from PIL import Image

im = Image.open("thresh.jpg")
pixel = im.load()
row, column = im.size
for y in range(column)
    for x in range(row)
        pixel = pix[x, y]

Question:

I want to save the pixel data in a text file. Suggest me some techniques to save the data.

Just create a file writer object and write the value of the variable pixel to that.

from PIL import Image

im = Image.open("thresh.jpg")
fil = open('file', 'w')
pixel = im.load()
row, column = im.size
for y in range(column):
    for x in range(row):
        pixel = pix[x, y]
        fil.write(str(pixel) + '\n')
fil.close()

Thanks for the reply but i am getting a `type error: expected a character buffer object` – Naveen Raja Feb 10 '15 at 05:08
I am getting error like `type error: expected a character buffer object` for the line `file.write(pixel)` – Naveen Raja Feb 10 '15 at 05:12
Now i have to save the 'pixel' with its positions x and y for eg: x=100 y=100 pixel = 255.... how can i save using `file.write` – Naveen Raja Feb 10 '15 at 05:20
i got it `fil.write(str(x)+str(y)+str(pixel)+'\n')` – Naveen Raja Feb 10 '15 at 05:24
yep, x and y are integers. You can't do like int + str . It won't do the concatenation. For this, you need to type convert the x and y. – Avinash Raj Feb 10 '15 at 05:26
ya i gave like `fil.write(int(x)+int(y)+str(pixel)+'\n')` it was not accepting integers it is accepting only `str(x)` – Naveen Raja Feb 10 '15 at 05:40
