If a cluttered desk is the sign of a cluttered mind, what is the significance of a clean desk?

Guess I won't worry too much about Christmas shopping that year.

Good thinking! There is a silver-lining in every cloud.

Because of the increase in the number of 'double flushes' the introduction of the so-called "low flow" toilets has actually increased water consumption.

Some people in the US sit in front of a turned off TV and find it more entertaining than turning it on.

Housewife to house painter:
"Let's go to the master bedroom and I will show you the spot my husband touches when he takes his pants off."

Painter: "Lady, I am not that kind of painter, besides I am married."

Doctor: "I can't find a cause for your complaint. Frankly, I think it's due to heavy drinking."
Patient: "In that case I'll come back when you're sober!"

I would feel so sorry for all the inovative folks at Yahoo.

I got one when I joined Daniweb around 2 years back, though I must admit it was more along the lines of the moderator not knowing what an infraction was meant for considering the infraction feature was newly introduced. ;-)

Well, an honorary infraction like that is a nice feather on your cap and should be cherished.

On a picture the easiest way to distinguish the A319 from the A320 is the location of the rear door with respect to the onset of the tail.

Here is mystery plane #50 (John McCain flew those in his early years)

If the first code you showed is part of a function you have to tell it that gold is a global variable, start your function code with

global gold

This must be specific to the Mac OSX. I wonder if PIL has a users forum, or a place you can ask.

Somewhere above your lines shown you have to give gold a starting value, most likely:
gold = 0

Just a helpful note, putting our remarks above the line makes your code much more readable:

def search_nested(mylist, val):
    """
    This function will search each cell of mylist for val and
    if found will return the entire row
    """
    #loops i from 0 to the length of mylist (num of rows)
    for i in range(len(mylist)):
        #loops j from 0 to num of cols in each row
        for j in range(len(mylist[i])):
            #print i, j  # my own debugging commented out
            #compare each cell to search value
            if mylist[i][j] == val:
                #if found, return entire row that the value was found in
                return mylist[i]
    #if value not found, return a string instead
    return str(val) + ' not found'


#define 2d list
nested_list = [[1,2,3],[5,6,7],[9,10,11]]  #define 2d list

#call function and display the value the function returns
print search_nested(nested_list, 1)

print search_nested(nested_list, 4)

print search_nested(nested_list, 6)

Also using python code tags give you highlighting:
[code=python]
your Python code here

[/code]

bachmabt's solution works in your case where you have:
nested_list = [[1,2,3],[5,6,7],[9,10,11]]
but for more complex nesting like:
nested_list = [[1,2,3],[5,6,7],[9,[10,11]]]
you may have eventually flatten the list.

I am really not a mind reader, so show us some code that gives the error!

Tkinter only displays gif and ppm images, to show the more popular jpg and png images you have to incorporate the Python image Library (PIL). Here is an example:

# load and display an image with Tkinter
# Tkinter only reads gif and ppm images
# use Python Image Library (PIL) for other image formats
# give Tkinter a namespace to avoid conflicts with PIL
# (they both have class Image) PIL is free from:
# http://www.pythonware.com/products/pil/index.htm

import Tkinter as tk
from PIL import Image, ImageTk

root = tk.Tk()
cv1 = tk.Canvas(root, width=500, height=500)
cv1.pack(fill='both', expand='yes')

# open a jpeg file into an image object
# image should be in the source folder or give full path name
image1 = Image.open("flowers.jpg")
# convert image object to Tkinter PhotoImage object
tkimage1 = ImageTk.PhotoImage(image1)

# tk.NW anchors upper left corner of image
# at canvas coordinates x=10, y=20
cv1.create_image(10, 20, image=tkimage1, anchor=tk.NW)

root.mainloop()

Be aware that there is a namspace conflict with class Image:

# load and display an image with Tkinter
# Tkinter only reads gif and ppm images
# use Python Image Library (PIL) for other image formats
# give Tkinter a namespace to avoid conflicts with PIL
# (they both have class Image) PIL is free from:
# http://www.pythonware.com/products/pil/index.htm

import Tkinter as tk
from PIL import Image, ImageTk

root = tk.Tk()
cv1 = tk.Canvas(root, width=500, height=500)
cv1.pack(fill='both', expand='yes')

# open a jpeg file into an image object
# image should be in the source folder or give full path name
image1 = Image.open("flowers.jpg")
# convert image object to Tkinter PhotoImage object
tkimage1 = ImageTk.PhotoImage(image1)

# tk.NW anchors upper left corner of image
# at canvas coordinates x=10, y=20
cv1.create_image(10, 20, image=tkimage1, anchor=tk.NW)

We all know, but we don't do your homework! Read the DaniWeb rules.

But, why would someone choose Java over Python? Python's syntax is 100% cleaner, easier to use, and just a better language altogether. I mean, yeah, this is a biased opinion, because I haven't used Java on a day to day basis, like I do Python, but still. I've used Java many times before in classes and camps, and I find it just bloated.

Java has been taught by college CS departments for many years. The typical inertia shown by CS staff makes certain that Java will be taught for many more years to come. There are hordes of Java programmers out there. Also Java, being more complex, ensures job security since development is slower and more programmers are needed to do the job.

Python, being easier and quicker to teach, would of course reduce the number of instructors too. Oh my!

Simple debugging using the Python debug module pdb:

# test the built-in Python Debugger (Pdb in the Python reference)
# at the debugger's '(Pdb)' prompt you can type  h  for help or
# more specifically use   h step  or   h next

import pdb

#help('pdb')

# once the '(Pdb)' prompt shows, you are in the debugger
# and you can trace through by entering:
#
# next (or n) which goes line by line and does not get
# into functions or into every iteration of a loop
#
# step (or s) which is more detailed and for instance
# loops through an entire range()
#
# so use next to get where you want to be and then use step,
# once you have all the details you need, use next again

pdb.set_trace()

# now you can test the following code ...

def hasCap(s):
    """returns True if the string s contains a capital letter"""
    for num in range(65, 91):
        capLetter = chr(num)
        if capLetter in s:
            return True
    return False

str1 = 'Only pick up strings without Capital letters!'
str2 = 'only pick up strings without capital letters!'

# test the function hasCap()
if hasCap(str1):
    print "str1 has a capital letter"
else:
    print "str1 has no capital letter"

if hasCap(str2):
    print "str2 has a capital letter"
else:
    print "str2 has no capital letter"

You need to play with this a little to get familiar with the pdb debugger.

I have found some bugs just using the Python debugger module pdb:

# test the built-in Python Debugger (Pdb in the Python reference)
# at the debugger's '(Pdb)' prompt you can type  h  for help or
# more specifically use   h step  or   h next

import pdb

#help('pdb')

# once the '(Pdb)' prompt shows, you are in the debugger
# and you can trace through by entering:
#
# next (or n) which goes line by line and does not get
# into functions or into every iteration of a loop
#
# step (or s) which is more detailed and for instance
# loops through an entire range()
#
# so use next to get where you want to be and then use step,
# once you have all the details you need, use next again

pdb.set_trace()

# now you can test the following code

def hasCap(s):
    """returns True if the string s contains a capital letter"""
    for num in range(65, 91):
        capLetter = chr(num)
        if capLetter in s:
            return True
    return False

str1 = 'Only pick up strings without Capital letters!'
str2 = 'only pick up strings without capital letters!'

# test the function hasCap()
if hasCap(str1):
    print "str1 has a capital letter"
else:
    print "str1 has no capital letter"

if hasCap(str2):
    print "str2 has a capital letter"
else:
    print "str2 has no capital letter"

The hottest day on record was 70 degrees Celcius (158 degrees Fahrenheit), and was recorded in the city of Majubea in northern Sudan. Time to hit the pool!

This would be my dream car.

I think plane #46 is an Airbus A319.

Plane #48 is a MIG15 with Dutch markings(?)

Genarally this is done this way:

def get_int(low, high):
    """
    the function will loop until an integer number within the
    given low and high range has been entered
    """
    prompt = "Enter an integer number between %d and %d: " % (low, high)
    while True:
        try:
            n = int(raw_input(prompt))
            if low <= n <= high:
                return n
        except ValueError:
            print "Integer value in range required!"

# test the function
n = get_int(1, 50)
print n

Then there is Boo, has a Python like syntax and ties in with C#. Vegaseat left a code snippet of Boo code at:

No one died when Clinton lied.
Sorry sight that rhyme implied.
Has the time finally arrived,
When we must to that poor mentality be subscribed?
Glutton for pleasure, this Clinton was
At the eve of the September attack.
Some may say how lucky the man was
When the strike came, it was not his watch.
Others may feel, it ain't right not to cash
What he helped and allowed to be set up.
In his legacy perhaps a tiny stain
Regardless, skeptic I must remain.
For what form of luck can be bestowed,
that compensate for such a large nose?

I don't think I would ever dare to publish such poor peotry! Bold font too!

Here is an example that should get most of the way there. All you need to do is to supply the search string from the listbox selection:

# searching a long text for a string and scrolling to it
# use ctrl+c to copy, ctrl+x to cut selected text,
# ctrl+v to paste, and ctrl+/ to select all

import Tkinter as tk

def display(data):
    """creates a text display area with a vertical scrollbar"""
    scrollbar = tk.Scrollbar(root)
    text1 = tk.Text(root, yscrollcommand=scrollbar.set)
    text1.insert(0.0, data)
    scrollbar.config(command=text1.yview)
    scrollbar.pack(side='right', fill='y')
    text1.pack(side='left', expand=0, fill='both')
    
    # could bring the search string in from a listbox selection
    pattern = "Chapter 3"
    # line.char(lines start at 1, characters at 0)
    start = "1.0"
    # returns eg. "31.0" --> line 31, character 0
    index = text1.search(pattern, start)
    # scroll text until index line is visible
    # might move to the top line of text field
    text1.see(index)
    
    
root = tk.Tk()

str1 = """\

That sort of thing is usually done by subprocess.Popen() or os.popen() functions.

I always thought you were some kind of car buff. What happened?

Okay, I am still a car buff, but I thought that sounded too Lithuanian.

Funny movies...
i heard sometimes people drink to keep their body still warm (in winter). this reason can be accepted or not?

In Siberia they drink vodka because most other 'drinkems' are frozen solid.

Very interesting indeed!
