Python has a pretty fast algorithm built-in called an adaptive merge sort. Here is an example:

# sort a list of names without changing the original list
# uses the high speed sorting algorithm built-into Python

name_list1 = ['Frank', 'Mark', 'Hank', 'Zoe', 'Bob', 'Carl', 'Al']
name_list2 = sorted(name_list1)

print "Original:"
print name_list1
print "Sorted:"
print name_list2

"""my output -->
Original:
['Frank', 'Mark', 'Hank', 'Zoe', 'Bob', 'Carl', 'Al']
Sorted:
['Al', 'Bob', 'Carl', 'Frank', 'Hank', 'Mark', 'Zoe']
"""

If you have to create your own sorting algorithm, go with a selection sort. It is relatively slow, but rather easy to understand.

A selection sort of a list of numbers is pretty simple. You start
with two lists, let's call the original unsorted list the start_list
and you have another list call it the end_list which is empty at
the start.

If you want to sort ascending (lowest value first) you get the lowest
value of start_list using lowest = min(start_list) and append it to
the end_list with end_list.append(lowest). Now remove this value from
the start_list with start_list.remove(lowest) and repeat until the
start_list is empty and return the end_list with the sorted values. The repeat can be done with a while loop.

Have you no shame?

saw it in 3d...great graphics...lame plot though...just my thought on it...

I agree, but then this is Hollywood, entertainment makes the money, a plot might happen.

I think she was referring to the founders of the Tea Bag Party.

Now it works, nice concept!

I would say your indentations are a little screwy. Indentations are very important for Python to designate statement blocks.

Duck Typing comes to mind.

Very nice idea.

Of course i write python scripts... i just use the shell to test fast some functions AFTER i find bugs in my script...
...
...

Then this code you gave:

myvalue = 16

command2 = r"\x03\xa2\x%02x" % myvalue

# JUST OUTPUT THE STRING INSTEAD OF PRINTING IT
command2  #\\x03\\xa2\\x10

should not give any display. See what I mean?

In essence this would be the search of a 'subset' in a set:

# search for a subset in a set (Python3 syntax)

set1 = {'red','green','blue','black','orange','white'}
set2 = {'black', 'green'}

print('These are the colors common to set1 and set2:')
print(set1 & set2)

"""my result ==>
{'green', 'black'}
"""

Please read the note on homework help. We only help those who show at least some coding effort.

The module psyco compiles to 386 machine code rather than byte code. It speeds things up a little for the Python interpreter.

To my knowledge two complete OS have been written using mostly Python, both of them are less than ideal and are used for research purposes only. Python is a high level language and has not been designed for such a low level task!

I trained there and it didn't stop my drinking problem!

On question four I can say that most mistakes in our organization are now made on the computer.

Don't you just hate signature spammers! They make the pasta you ate come right back up again! Who the heck cares about the cheap bumper stickers they peddle.

Directed at ktsangop,

Are you writing your program with an editor, save it as a .py file and then run it, or are you simply running it directly from the Python interpretive shell?

If you run it from the shell, we can argue till the cows lay eggs.

Usually homework like that asks for change with the least amount of coins.

Just a short explanation on how to create and access a Python package:

"""
assumes that you are using Python31 installed on the c drive
1) create a directory c:/Python31/MyModules
2) write an empty file __init__.py to that directory
   ( this makes MyModules a package)
3) write a test module module1.py to that directory
   ( has one code line --> text = "text from module1" )
4) test module module1.py in c:/Python31/MyModules
   with the code below, this file can be saved anywhere

since package directory MyModules is in the Python path
it will be found, remember package names are case sensitive
as are module names
"""

import MyModules.module1 as mm_module1

print(mm_module1.text)

Just change your drive and Python version as needed. On Linux you may need root permission.

Really not very complicated, just follow this sequence of actions:

"""
assumes that you are using Python31 installed on the c drive
create a directory c:/Python31/MyModules
then save this file in that directory as __init__.py
basically an code-empty file with an optional explanation
it will make MyModules a package
"""

Now directory MyModules is a package and you can put your custom modules in it, for instance this test module:

"""
now create this simple test module
and save in c:/Python31/MyModules as module1.py
"""
text = "text from module1"

Next write some code to test module1, this file can be saved anywhere and when you run Python (in this case Python 3.1.1) it will find package directory since it is in the Python search path:

"""
assumes that you are using Python31 installed on the c drive
1) create a directory c:/Python31/MyModules
2) write an empty file __init__.py to that directory
   ( this makes MyModules a package)
3) write a test module module1.py to that directory
   ( has one code line --> text = "text from module1" )
4) test module module1.py in c:/Python31/MyModules
   with the code below, this file can be saved anywhere

since package directory MyModules is in the Python search path
it will be found, remember package names are case sensitive
as are module names
"""

import MyModules.module1 as mm_module1

print(mm_module1.text)

My Sony Multimedia computer is slowly giving up after 7 years of heavy use, so I am replacing it with an economically priced Dell Inspiron 545 (it's getting tough to find a regular desktop computer).

Wow, what a difference 7 years make. The price is now 1/4 of the Sony. The hard disk has jumped from 48Gb to 640Gb and internal memory is now 6Gb. It will be my first experience with Windows 7 (64bit). Wish me luck!

The old Sony will be properly recycled.

If you want to use drag and drop to design your widget layout then the PyQT GUI toolkit comes with QTdesigner, see:

The wxPython GUI toolkit can use BOA constructor, see:

Another nice drag and drop utility for wxPython is wxGlade.

Shorten the list and add a temporary print for testing. See what that will do for you:

# shorten list for test
a = range(1, 10)
b = []
d = 0
for n in a:
    while n != 1:
        if n % 2 == 0:
            b.append(n)
            n = n/2
        elif n % 2 != 0:
            b.append(n)
            n = n*3 + 1
        else: b.append(n)
    print b, d, len(b)  # test
    if len(b) > d:
        d = len(b)
        b = []

Today was Super Bowl Sunday (final pro football game of the season) here in the US. One of the traditional foods to watch the game with are chicken wings, honey bbq in my case. I had six friends over and we went through 5 pounds of wings and a couple of six packs of local microbrew beer. Seeing the New Orleans Saints win was a thing of beauty!

Almost two more years to wait until this spectacular event will happen. Makes the rest of the wait boring.:)

Anyway, yesterday I enjoyed some cherry ice cream and it had a part of a pit in it, enough to chip my tooth and now I have to spend some time at the dentist.

I have only python 2.5 installed and i can find PIL in the Pythons installation directory. I use a IDE called PyScripter. When i run the program from the IDE it works fine. But it throws error when i run it from the command line.

What do you mean with run it from the command line? What is your command?

Calm down, nobody has called you anything!

The thread caters to project ideas that are for the beginner. However beginners are at all sorts of levels in their learning progress. Any project takes some research, otherwise it isn't a project!

I have enjoyed the sticky's project ideas very much. Please put your clever Raffle project back into the thread. Avoid the unsubstantiated extra comments about other projects. If you manage to freeze up Python on a program you wrote, go to the regular forum and ask questions. This way you won't ask other folks to clutter up this nice thread/sticky with answers. That is what the rules imply.

It looks like the word Beginner should have been replaced by Python Enthusiast or something.

Simply loop your code a million times and time the whole thing. There is also module timeit.

I saw Gallagher on TV once, what a riot! People in the front rows had to cover with plastic, as he was hitting those water melons on stage with a big hammer.

The government also has the power to print money. lots of it! A measly 14 trillion, ha, just a drop in the bucket!

What is important is the annual cost of the debt compared to annual GDP. That comes to about 5% of GDP. Once you have to borrow money to service the debt, then you are in deep trouble! We are not quite there yet!

The debt that our major banks have accumulated with funny money and fake loans to each other, far exceeds the national debt.
