Importing a tuple to a list from a function

I'm trying to modify pixels using range in a loop but I can't import the range from size function.
load = bnw.load()
loadpx = [
(a),
(b)
]
bnw.size(loadpx)
print(loadpx)
for x in a:
for y in b:
new = load[x,y] + 10
if new > 254:
new = 254
bnw = new
The output from bnw.size should be the number of pixels the image has ex. (1920,1080). after knowing the size a is inputted to the x and b to y.
the full code withe the first answer returned the same error

Brand new to scipy/numpy and attempting some batch manipulation

So, I have a bunch of scanned images with annoying white around them that I want to remove. I'm prepping an algorithm using numpy arrays to find the closest pixel row and columns of complete white, cropping them to those positions. This is my code:
from scipy import misc
import os
import datetime
a0 = datetime.datetime.now()
print("Imported at " + str(a0))
def run():
inputdir = '/Users/nicholasezyk/Documents/funeralhomescans'
os.chdir(inputdir)
#batch image renaming
counter = 1
for file in os.listdir(inputdir):
if file.endswith('.jpg'):
img = misc.imread(file)
print(file + ' being analyzed.')
cropx = -1
cropy = -1
lx = img.shape[0]
ly = img.shape[1]
countx = 0
county = 0
while countx < lx:
pix = img[countx, 0]
if pix == (255, 255, 255):
tempcountx = 1
scorex = 1
while tempcountx < ly:
if img[countx, tempcountx] == (255, 255, 255):
scorex = scorex + 1
tempcountx = tempcountx + 1
if 1000 * (scorex / ly) > 1000:
cropx = tempcountx
break
while county < ly:
pix = img[0, county]
if pix == (255, 255, 255):
tempcounty = 1
scorey = 1
while tempcounty < lx:
if img[tempcounty, county] == 255:
scorey = scorey + 1
tempcounty = tempcounty + 1
if 1000 * (scorey / lx) == 1000:
cropy = tempcounty
break
send = img[0:cropx, 0:cropy]
misc.imsave('crop' + str(counter) + '.png', send)
print(file + ' cropped and exported as ' + 'crop' + str(counter) + '.png')
run()
Right now, this is my console statement:

Since I'm unfamiliar with the syntax, if anyone could help me figure out how to work with numpy arrays, that'd be fantastic.

Using PIL, how do i save an image from manipulated after using .load()?

How do I save an image file from data manipulated using image.load()?
This is my code used to merge two pictures of the same size
from PIL import Image
import random
image1 = Image.open("me.jpg")
image2 = Image.open("otherme.jpg")
im1 = image1.load()
im2 = image2.load()
width, height = image1.size
newimage = Image.new("RGB",image1.size)
newim = newimage.load()
xx = 0
yy = 0
while xx < width:
while yy < height:
if random.randint(0,1) == 1:
newim[xx,yy] = im1[xx,yy]
else:
newim[xx,yy] = im2[xx,yy]
yy = yy+1
xx = xx+1
newimage.putdata(newim)
newimage.save("new.jpg")
When I run it I get this error though.
Traceback (most recent call last):
File "/home/dave/Desktop/face/squares.py", line 27, in <module>
newimage.putdata(newim)
File "/usr/lib/python2.7/dist-packages/PIL/Image.py", line 1215, in putdata
self.im.putdata(data, scale, offset)
TypeError: argument must be a sequence
Isn't the dictionary from using .load() a sequence? I can't find anyone else on google having this problem.

The dictionary (which isn't really a dictionary) returned by load is the data in the image. You don't have to reload it with putdata. Just remove that line.
Also, use a for loop instead of a while loop:
for xx in range(0, width):
for yy in range(0, height):
if random.randint(0,1) == 1:
newim[xx,yy] = im1[xx,yy]
else:
newim[xx,yy] = im2[xx,yy]
Now there's no need to initialize and increment xx and yy.
You could even use itertools.product:
for xx, yy in itertools.product(range(0, width), range(0, height)):
if random.randint(0,1) == 1:
newim[xx,yy] = im1[xx,yy]
else:
newim[xx,yy] = im2[xx,yy]
