[Tutor] Replacement for 'Find' Module
On my Windows XP box running Python 2.4, I attempted to use the 'find'
module per the example in Programming Python (Ch. 2) - i.e.:
>>>import find
>>>find.find('*')
However, Python didn't find the find module. The docs say it's now
deprecated, but don't point to what tool should be used to replace
find. My Googling efforts haven't been fruitful so far. Could
someone please point me in the right direction?

Nearly everything is possible; you just have to order your thoughts correctly :-) In this case, you're looking for a way of mapping from cards to values. Python has a mapping type built in, called a dictionary.

Re: [Tutor] Replacement for 'Find' Module
You could probably do something like this... (Note: This example is
for Linux - but you can adapt it fairly easily to Windows.)
# E.g. Find every .inf file on a CD-ROM.
path = '/cdrom'
# 'E:\\' or whatever for Windows
inf_list = []
for root, dirs, files in os.walk(path):
for current_file in files:
if '.inf' in current_file:
inf_list.append(os.path.join(root, current_file))
I, too, would be interested in knowing if anyone has a better way to do this :)
You would probably combine the 'glob' module with os.walk to grab what
you wanted, and build the list of files that way.
Lemme know what you figure out.

Re: [Tutor] How can I make this run right?
I'd do it like this... And there's probably an even quicker way, if
you really sat down and thought about it.
n = int(raw_input("Number: "))
x = n-1
while x > 1:
n *=x
x -=1
print n
The reason why it isn't working is because of
"
while x > 1:
x -= 1
"
When your program hits this point it stays in the while loop,
subtracting 1 from x each time, but not multiplying anything anymore,
until it hits break. So your program does this.
Number: 4
n = 5
x = 4
t = 20
x = 3
x = 2
x = 1
BREAK.

What output did you expect? What did you get?
Without that information we have to read the code and guess what you

One thing you might find handy is IDLE's debugger (if you use IDLE).
Turn it on under Debug / Debugger. Make sure the "Source" checkbox is
checked. Then hit the step button to run your program in "slow motion"
so you can see everything it does one step at a time.
(You might have to temporarily click the output window to the front
when the raw_input wants you to type a number)

Hi All, I'd like to write some web gallery software from scratch for my girlfriend. I've looked at the PIL (python imaging library) and I'm using it to generate thumbnails from given images. Something else i'd like to get done now though, is building an index of images. Are there any libs suited for this? basically I want an text index of images, which contains the main image name, the thumbnail name, and a description. a new image can be added to the index either by adding it via ftp, or through an html upload form with the comment in the form. So basically, i'm after advice on indexes. thanks for reading, Paul ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Directly Quoted From the Python Cookbook
1.3 Constructing a Dictionary Without Excessive Quoting
Credit: Brent Burley
1.3.1 Problem
You'd like to construct a dictionary without having to quote the keys.
1.3.2 Solution
Once you get into the swing of Python, you may find yourself
constructing a lot of dictionaries. However, the standard way, also
known as a dictionary display, is just a smidgeon more cluttered than
you might like, due to the need to quote the keys. For example:
data = { 'red' : 1, 'green' : 2, 'blue' : 3 }
When the keys are identifiers, there's a cleaner way:
def makedict(**kwargs):
return kwargs
data = makedict(red=1, green=2, blue=3)
You might also choose to forego some simplicity to gain more power.
For example:
def dodict(*args, **kwds):
d = {}
for k, v in args: d[k] = v
d.update(kwds)
return d
tada = dodict(*data.items( ), yellow=2, green=4)
End Quote
Hi guys,
Above is a direct cut & paste from the book (hope I am not violating
any thing...). I've read the Python docs and can understand the first
def example ok, I suppose. However I would like some detailed
explaination about the second example, the dodict one. How exactly
does it work? It just puzzles me why this would be more powerful or
better, even though I can understand and agree that re-writting
programs makes good practice. In fact that's what I am looking for
from reading this book. Just hope someone can walk me through this
simple code. Thanks for the help.

complains if I use root by saying:

Re: [Tutor] Would like some help
Howard,
I believe what's happening in the second example is that you can combine
dictionaries.
...
>>>d2 = {'hello':1,'hi':2}
>>>print d2.items()
[('hi',2),('hello',1)]
so in the second example you can just pass it a list of elements (.items())
and it will concatenate (append?) these to the new dictionary.
hope that helps.

This recipe is obsolete; since Python 2.3 (at least) you can pass keyword args
directly to the dict() constructor:
data = dict(red=1, green=2, blue=3)
> You might also choose to forego some simplicity to gain more power.

This can now be written as
tada = dict(data, yellow=2, green=4)

Most likely you need "root" privileges to change anything under "/usr". If you trust the code, try running it again as "root" (also known as "super-user"). Only do that if you're certain that the code is clean (i.e. no viruses, trojans, spyware and/or worms)! (Sorry, I don't know anything about Linspire, or else I would guide you step by step on how to do that!. In general, try "sudo" with your own password, or "su" with root's password.)

your problem is easy to see...

> >> x = n-1
> >> while 1:

think about it for a *while*...
Hint *while*
hint hint *change the while*
hint hint hint *the inner while*
nathan I see that you want to do n!(factorial)
but when you explained it you just said you wanted number!
which is confusing because I think everyone thought you were just excited.
you could always use a recursive function for factorial, IE.
def factorial(n):
if n > 1:
return factorial(n-1) * n
else:
return n
HTH,

P.S. Try to fix yours it'll help you. tell me if you get it working
correctly.

Dear Nathan,
Everyone is giving you very good hints but seems to me you keep to
resist :-)
Looks like you always wait for complete solution, dont you?
Here it is. There is one add and two changes. Can you see them?
n = int(raw_input("Number: "))
x = n-1
t=n
while 1:
t = t*x
if x > 1:
x -= 1
else:
break
print t
Its not the best solution for number!, but it is yours (and a bit of
mine :-) )

I wrote this in a script for limited globbing:
if cd:
toss = os.path.join(trashcan, os.path.split(i)[1])
pwd = os.getcwd()
else:
toss = os.path.join(trashcan, i)
if toss[-1] == '*':
crumple = []
if cd:

for i in l:
crumple.append(os.path.join(cd, i))

crumple = os.listdir('.')
for i in crumple:
if i.startswith(toss[:-1]):
junk.append(i)

Your function didn't look like the usual factorial function. FWIW here is my version :-) def factorial(n): result = 1 for x in range(2,n+1): result *= x return result By avoiding while loops you avoid all the mess of trying to maintain the counter - one of the most common causes of errors in programming! For a different approach see the recursion topic in my tutor.

[Tutor] convert a file from plaintext(Ascii) to unicode? very quick questions
Hello guys! Is there a way to convert a file from plaintext(Ascii) to unicode? I have found all my notes about moving between hex., int's, chr's, ord's, etc, but all of these things were only riddle exercises to me and I have a hard time keeping them straight. I'm pretty sure I knew the answer to this and now cannot find it anywhere (even googling through my old tutor posts!) Does anyone have a quick answer/pointer?

List: I'm forwarding this private message(hope you don't mind Denise) I personally have no idea what to do, but someone else might be able to help. -Luke - Forwarded Message - text is a list, so you can't encode it. but you can iterate over each of the elements and encode them.

[Tutor] From file2.py append an item to file1.py combobox
Hi to all:
How can I append some data from file1.py to a combobox
on file2.py?
I know, if you want to append data to a combobox
inside the same script, I would be like follows:
# file1.py
import wx
class Myframe(wx.Frame):
def __init__(self, *args, **kwds):
...
self.mycombobox = wx.Combobox(...
...
# and then...
self.mycombobox.Append("Item")
# would append to the combobox a new item.
# file2.py
# So here are my problems...
# I got:
import wx,file1
class Subframe(wx.Frame):
def __init__(self, *args, **kwds)
...
def Mymethod(self,event):
file1.Myframe.mycombobox.Append("Item")
# and it doesnt work...
# file1.Myframe.self.mycombobox.Append("item")
# does not work either..
What can I do? thanks in advance
Daniel.

Re: [Tutor] convert a file from plaintext(Ascii) to unicode? very quickquestions
I think Luke's suggestion will work if you use f.read() (to read the whole file as a single string) instead of f.readlines() and f.write() instead of writelines().
