Wow :) very impressive and exactly what I was looking for. Thanks!

I have an array of numbers and want to print out how many of each number there are in the array. My method works but I was wondering what a more efficient way of doing this would be. I figure a loop...

Thank you guys for your replies!

Hi, I'm trying to run code that asks a yes or no question. If a yes or no isn't entered, then the question will continue to re-ask say every 3 seconds until a yes or no is entered. Here's the basics...

jlm699, thank you! That helped alot!

I put a loop up of numbers to show that I can run a loop with a given amount of chars. I can add 2 more values to it if a list of 5 is what I'm after. Running the numbers loop will produce:
0 0 0
0...

Thanks for the reply. Here's part of my problem with that:

for i in range(97,122):
for j in range(97,122):
for k in range(97,122):
print chr(i),chr(j),chr(k)

That type of loop will...

How can I write a loop using letters instead of numbers so it looks like this:
2 sets used 'a-z' and 'A-Z'
aaaaa
aaaaA
aaaAa
aaAaa
and so on:
aaaAA
then on to b:
bbbbb

Yes it worked....I did finally figure it out.

:) I think I figured it out:


y = 0
for x in range(width):
if pixel_dict[(x,y)][2] > 0:
print( "(%d, %d): %s"% (x, y, pixel_dict[(x, y)]) )

When I run this:

from PIL import Image

img = Image.open('10x.bmp')
for pixel in img.getdata():
if pixel[2] > 0:
print pixel

it works but doesn't have the x,y positions. When I...

I'm bumping this thread to see if I can get a reply....the code by sneekula works for what I need but I can't figure out how to get it to just print out the ones where the 'B' value is greater than...

I wanted to edit the above thread but anyway.....I got it to loop through so now the last thing I need to work out is how to get it to print out just the values where 'B' is > 0, like in the first...

Wait a sec.....after playing around with sneekula's code for a while, I realized that it works, it's just printing out 1 row.

# testing ...
# show contents of the first row
y = 0
for x in...

Thanks for the replies. Sneekula, that's along the lines of what I'm after but when I run that on the image I have, it doesn't print out the B values like with the first code I posted.
My code on my...

I'm trying to locate the 'x' positions of certain pixels. Here's and example image:

if I run this code it gives me the 88 'odd' pixels that I'm...

Thanks!

I can't seem to figure out what's wrong with this simple code. I have a user input and if it matches prints out 'That's good', if not prints out 'Too bad' but how can I get the input to ignore being...

Works great, thanks!

I am printing out the R,G,B values of an image and get results like this:

(30, 0, 0)
(29, 0, 0)
(28, 0, 0)
(27, 0, 0)
(26, 0, 0)
(25, 0, 0)
(24, 0, 6)
(23, 0, 0)

Wow....now if that prints out that particular list of tuples, how could you go about locating a pixels x,y position? Let's say one of the R,G,B tuples was this: (255,0,9) and you wanted the position...

Hi, how can I open an image and get the R,G,B values of just the first line?


from PIL import Image

im=Image.open("image.bmp")
img=im.getcolors()
print img

Ok, thank you. That will work.

What can I use to examine the RGB values of an image :(

Here's an example image:

Hi I'm trying to use PIL to get data from an image and find 'unusual' RBG values but haven't found the right way.


Import Image, PIL

im=Image.open("image.bmp")
ans=im.getdata()
print ans

I'm trying to auto send a form submission to a website but it isn't working. I've done this before and it worked but for some reason, using the same basic code, it doesn't seem to submit it. I'm...

Wait, I think I've got it:


>>>x=1234567
>>>sum(int (i) for i in str(x)])
28

Something like this will work, I just have to get it to the point that it does it without the 'raw_input'......

>>>sum([int(i) for i in raw_input("Enter integer: ")])
Enter integer:1234567
28

I know python has math functions like 5+6 and 5*6 and 5/6 etc...but I have something like this:
x=575124357

and need to add them all together:
5+7+5+1+2+4+3+5+8=40

Ah....! That's it! I didn't realize I could add 'not' like that. Thanks again

Yes :) just what I was looking for, thank you

I have code that when executed will give me a long list output, which is fine, but how can I get it to print without the parenthesis and commas? example: answer =('7', 'Q', '5', 'H', '9', '4', '3',...
