[Tutor] walking directories
Hi folks,
Im running python2.4 on linux.
I have many python scripts in various directories of varying depth under my
home directory, and I need to change one line in each of these files.
I thought about using os.walk with os.path.join eg
>>> for r,d,f in os.walk('.'):
... print os.path.join(r,d,f)
but I get this error
Traceback (most recent call last):
File "", line 2, in ?
File "/usr/local/lib/python2.4/posixpath.py", line 60, in join
if b.startswith('/'):
AttributeError: 'list' object has no attribute 'startswith'
which makes sense.
I know I can use glob.glob on the current directory, but Im struggling to see
how I can access these files, change them and save the changes.
Im also a little annoyed with myself cos I feel that I really should know how
to do this by now.
If anyone can just give me a pointer in the right direction I would be very
grateful.
Many thanks
Nick .

Richard, if you try to print sys.argv[1:] when sys.argv only contain sys.argv[0] then you are bound to get an empty list returned, [] .

[Tutor] reading from stdin
Hi folks, I've been pondering how to get python to read from a pipe outside of itself, sort of. For example I tried a simple python prog to do a grep, eg # ps -e | myprog.py cron would give this output 3778 ?00:00:00 crond same as # ps -e | grep cron The way I did this was to use sys.stdin.readlines() to get the output from the pipe. Here is the program: [code] import sys, glob args = sys.stdin.readlines() # found on the net pat = sys.argv[1] for i in args: if (i.find(pat) != -1): print i, [/code] My question is am I getting the output from the pipe in the correct way ? The way Im doing it works (so far) but should I be doing it another way ? Many thanks Nick . ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] [HELP]how to test properties of a file
I've gotten into the habit of just using the os.?_OK stuff.
eg
>>> import os
>>> os.access('/', os.W_OK)
False
>>> os.access('/tmp', os.W_OK)
True
Thats gotta be simple if I understand it lol :)

Alan Gauld wrote:
The simplest, IMHO, is :
try:
f = file(filename, "w")

print "The file is not writable"
Of course, not that this method empty the file if it is writable !
The
best is to just put your IO code in such a try block ... That way,
you're sure the file has the right mode.
Its not really the simplest, its not efficient and it might be
dangerous
if the file is not empty. At the very least open using 'a' to avoid
obliterating the file!!
However the os.stat function and stat module do what you want safely
and more comprehensively:
---
Help on module stat:
NAME
stat - Constants/functions for interpreting results of
os.stat() and os.lstat().
FILE
/usr/lib/python2.3/stat.py
DESCRIPTION
Suggested usage: from stat import *
DATA
ST_ATIME = 7
ST_CTIME = 9
ST_DEV = 2
ST_GID = 5
ST_INO = 1
ST_MODE = 0
ST_MTIME = 8
ST_NLINK = 3
ST_SIZE = 6
ST_UID = 4
S_ENFMT = 1024
-
The constants above are the indices into the tuple returned by
os.stat()
That will tell you most of the things you need to know,
check the docs to find out what they all mean.
For your purposes the important one is ST_MODE.
So
import os
from stat import *
status = os.stat('somefile.txt')[ST_MODE]
if status & S_IWRITE: print 'writable'
elif staus & S_IREAD: print 'readable'
else: print 'status is ', status
Notice you have to use bitwise AND (&) to extract the status bits.

Re: [Tutor] Are Empty "Placeholder" Functions possible?
Hi John,
you can use 'pass' . This works the same as with exceptions, eg
try:
open('somefile')
except IOError:
pass
so we can have
class doNothing:
def __init__(self):
pass
def boring(self, other):
pass
Hope that helps :)

Subject: [Tutor] Are Empty "Placeholder" Functions possible?
Is there a way to create an empty function definition with no lines of code
in it? In my coding style I will often do this ( in other languages ) for
RAD just to remind myself that I will need to implement the function later.
Example: For a file handling class, I may need functions such as
copy,delete,move,etc so I want to start off with:
class FileHandler:
def __init__(self):
def copy(self):
def delete(self):
.
.
.
then in my driver/aka testing file:
import FileHandler
def main()
MyHandler = FileHandler()
print "Handler Created."
main()
Right now, this won't work as the compliler will error on functions with
nothing in them. Is there a "no-op", "do nothing", or some similar command I
can put in the empty functions to keep the compiler/interpreter from
erroring on them? This would really help speed up my development so that I
can create the class skeleton quickly and then implement each function and
test it as I go.

[Tutor] Should I be thinking of threads for this ?
Hello folks, I have the following code taken from the Twisted examples - [code] # filewatcher.py from twisted.application import internet def watch(fp): fp.seek(fp.tell()) for line in fp.readlines(): sys.stdout.write(line) import sys from twisted.internet import reactor s = internet.TimerService(1.0, watch, file(sys.argv[1])) s.startService() reactor.run() s.stopService() [/code] I find this piece of code amazing and I am keen to put it to use. If I run './filewatcher.py myfile' it will print out any changes made to 'myfile', very similar to 'tail -f' . Now if I want to have this program monitor several files at once I could run './filewatcher.py file1 file2 filex' or './filewatcher.py file1 & ./filewatcher file2 & etc' both with minor modifications to the code, but I think that could cause performance problems relating to the OS. So I'm thinking I will need to learn python threads (no bad thing) instead, but Im hoping that someone could tell me if that seems the best way to go ? I will be getting to grips with python threads anyway but I'd appreciate any input on this. Many thanks, Nick . ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

The default install of python on Mandrake probably install the python executable in /usr/bin/python. /usr/bin/ is in your PATH, so if you put PATH=$PATH:/usr/local/Python-2.4.1 in /etc/profile it will still pick up the default python install. Try typing 'which python' at the command line and see what it picks up. Chances are it will be /usr/bin/python. You could solve this by either putting PATH=/path/to/my/wanted/python/dir:$PATH in /etc/profile (or ~/.bash_profile) or by putting an alias in ~/.bashrc, such as 'alias python='path/to/my/wanted/python/dir/python'. What I must stress is that you do not overwrite your default python installation, leave it as it is, otherwise many of mandrakes GUI tools will no work. I hope that helps, feel free to ask more questions about this as I have had to overcome the same issue on RHEL serveral times.

[Tutor] Global var problem
Hi Folks, messing about with classes I've come across something basic that I don't understand. Take this class class T: def p(self): print x if __name__ == '__main__': x = 1 t = T() t.p() This outputs 1 Now this class T: def p(self): x += 1 print x if __name__ == '__main__': x = 1 t = T() t.p() This outputs UnboundLocalError: local variable 'x' referenced before assignment So I tried this class T: def p(self): x += 1 print x if __name__ == '__main__': global x x = 1 t = T() t.p() but that gives me the same UnboundLocalError exception. This has got me confused. Why does the first example work ok, but not the second ? And in the third example I get the same error even after declaring x to be global.

Re: [Tutor] smtplib alternative???
Hi Adisegna, Lets say that you are [EMAIL PROTECTED] and you want to send email to [EMAIL PROTECTED], [EMAIL PROTECTED] and [EMAIL PROTECTED] . You setup SMTPLib to talk to the MX server for abc.com which all users on abc.com use to send email. SMTP connects to that email server and you can send emails to anyone you like (unless theyre blacklisted). So by telling python to use [EMAIL PROTECTED] (your ISP's mail server) you can send email to [EMAIL PROTECTED] (obviously), [EMAIL PROTECTED] (because your a member of abc.com) and [EMAIL PROTECTED] (again cos your a member of abc.com). However, if you want your emails to be received with a different address, ie your using the isp abc.com and you want to send an email to [EMAIL PROTECTED] and it to appear to have come from [EMAIL PROTECTED] then you will need to tell pythons smptlib to connect to the MX server for pinkstuff.com to send the email, and you'll probably have to be dialled in to pinkstuff.com. Webmail MX servers differ in that they require authentication so it doesnt matter which ISP your dialled in from. Generally smtp servers are only configured to send to or from domains in which they belong.

Hi Danny, Yes, when sending an email your mail client will always send the email to the mail server specified by the MX record in the authoritive domain. Usually the domain specificed after the @ symbol. The problem with smtplib is that I have to specify the mail server I'm sending email too. What if I wanted to send an email to 3 different people on three different domains hosted by 3 different mail servers? Smtlib prohibits this functionality. Do you see what I mean now...?

RFC821 seems to confirm this: http://www.faqs.org/rfcs/rfc821.html so what you're asking, to be able to send mail without an SMTP server, may not be possible. There is an 'smtpd' module that comes with Python: http://www.python.org/doc/lib/module-smtpd.html I'm also not sure I understand the reason you're trying to avoid talking to an outside smtp server. But again, I'm unfamiliar enough with how the SMTP email protocol really works that perhaps I'm just overlooking something. -- Arthur DiSegna Network Operations Center Authentium, Inc. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] Learning books
Hi Richard, I myself just about know enough python to help me in my job occasionally and to do some cool little hobby projects. When it comes to creating GUI's for my programs I always use pythoncard, see here www.pythoncard.org . It's very simple to use, and the tutorials on their site will have you up and running in no time. It's based on wxpython but you don't need to know wxpython to use it at all, unless pythoncard itself does not implement some functionality that you desire. The pythoncard mailing list is also very low volume and very helpful. As a side note, I am the senior unix admin for a uk financial corp and I know very well that learning perl would be the best 'prospective' language for me to get to grips with, but no matter what issue I come up with at work (or home) python is always, and I truly mean always, the better option. I wish you good luck with your python learning experience, and I'm sure that you will find it's also a very cool language to use. I can't help but feel that it is inevitable that it will eventually overtake perl as the scripting language of choice. I hope none of that went too far off topic :) Nick . > -Original Message- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > Behalf Of Richard > Sent: 23 December 2005 20:05 > Cc: tutor > Subject: Re: [Tutor] Learning books > > > First of thanks for all the great input from everyone!!! > > Okay, so I have been reading some of the tutorials around the net on > Python. great stuff I might add but I am getting all confused with the > TCL, xwwidgets etc. I want to be able to program and I am just using the > standard IDE that comes with Python.

Re: [Tutor] problems with the shebang line and linux
Hi Brian, it's the ^M characters that are catching you out here. Often files from a windows PC will have ^M as the newline char when viewed in linux/unix. On linux you should be able to check if a file has ^M in by running either 'vi -b filename' or 'sed -n l filename'. Try this with the file vi filename escape :%s/^M// That should get rid of all the ^M chars. (not on linux at the mo so not 100% sure). The ^M is done in vi by actually typing in 'Ctl-V M' not shift6 M. What I wrote above may not sound too clear, but feel free to email me off list if you need any vi or linux commandline help (altho ive never used ubuntu so anything ubuntu specific I wont be much use with).
