[Tutor] serial -->file tranfer
Hello, I have a modem connect to my Windows XP PC through a serial cable. I Want to transfer the file(e.g '.TXT' format) from XP PC to serial modem and also from Serial modem to winXP PC. Can anybody help me out how to do it in Python and provide some sample code or useful links so that I can proceed further in my project?? All help will be highly appreciated.

Try this to start, then turn into a service with FireDaemon,

Another advantage to shorter sleeps is it reduces the latency of anything else your program needs to do, such as exit gracefully, reschedule the event, or whatever. Not too short, because that uses more CPU time. It also makes a difference if the clock gets reset :) Cheers ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

time.sleep is not exactly accurate, so I would suggest that you use this
method, short 5 minutes or so and then do a sleep(10) or so in a loop to get
closer to the time.

Ah, very nice! (But all the '360's should be '3600', of
course.)
Also, there's no longer any need for the loop.
So:
=
#!/usr/bin/env python
#coding=utf-8
# KCTS.py
import time, os
timeStart = raw_input("Enter starting time as hh:mm:ss ")
if timeStart == "":
timeStart = "19:59:25"
print "starting time set as", timeStart
b = timeStart
(bhour, bmin, bsec) = b.split(':')
bsec = int(bsec) + int(bmin)*60 + int(bhour)*3600
act = time.localtime()
actsec = act.tm_sec + act.tm_min*60 + act.tm_hour*3600
wait = bsec - actsec
if wait < 0: # startTime is in next day
wait += 3600*24
print "wait is", wait
time.sleep(wait)
print 'Starting now'
os.startfile('http://www.kuow.org/real.ram')
=
I wish I knew how to change that last line so that it would do what
"E:\Programs\Real Player\realplay.exe"
http://www.kuow.org/real.ram
does at the command line--open Real Player at KUOW without calling my
browser.

It needn't to make this comparison in every 0.5 seconds.
Calculate how long to sleep and ask that from the pc.
import time
b = '20:00:00'
(bhour, bmin, bsec) = b.split(':')
bsec = int(bsec) + int(bmin)*60 + int(bhour)*360

Well said, Kent.
Here's a generic tip to anyone learning Python.
I learned Python after working professionally with several languages
for many years, including Java and Delphi, and I can say that Python
is *very* well designed, is implemented with the highest standards of
software engineering and caters to a rigorous and expert audience.
It is **extremely** unlikely that you will ever find a bug in the
interpreter or the built-ins if you are using a released version of
Python. I've been using Python professionally since 1998 and I never
stumbled upon a single bug anywhere in a released Python distribution.
Of course, there are bugs and even security hot-fixes are issued from
time to time. But I've never been affected by a Python bug in my
projects.
So it's better to assume that any strange behaviour is actually some
misunderstanding on your part than a bug.
Cheers,
Luciano

I'm having a lot of trouble with the windows scheduler. It wants a
password, and there isn't one. In any event, I'd like to do this with
Python, especially if I could have "a Python process running in the

You might consider passing the URL directly to the audio player. This is
usually all the web browser does for you, although its possible there's a
different URL defined on that page each time, but then you could parse the
page in python using urllib and re, or something similar. Not only that,
launching IE7 is a time and memory consuming activity, and definitely lacks
grace.
I dunno how your media player works, but this did the job for me (from the
command prompt):
"c:\Program Files\Real Alternative\Media Player Classic\mplayerc.exe"
http://www.kuow.org/real.ram
You could put this directly into your windows scheduler, and not use python at
all. Start Menu>All Programs>Accessories>System Tools>Scheduled Tasks
You'll get an option to set the command line at the end of teh wizard, if you
check "show advanced options"
You could have a python process running in the background that executed this
command through the subprocess module, at the appointed time. You could even
use something like FireDaemon to turn it into a service. But, it seems
better to use the windows scheduler.

Sidestepping slightly, the natural way to open a URL using
whatever's set up to do so is with os.startfile:
import os
os.startfile
("
http://whatever...ram")
I was going to say that, to use IE7 explicitly, you should
use the webbrowser module. But then I realised that, for
reasons which I'm sure are extremely good but which elude
me for now, iexplorer is not one of the registered browsers.
As a fallback, you can look for its apppath entry in the registry
and use subprocess to call that.
Turns out that
os.startfile('http://www.kuow.org/real.ram')
does the trick. (IE7 is my default browser.)
So the script that will work is:
==
#!/usr/bin/env python
#coding=utf-8
import time, os
b = '20:00:00'
while True:
a = time.strftime('%H:%M:%S')
#print a
time.sleep(.5)
if a == b:
os.startfile('http://www.kuow.org/real.ram')
break
==
Thanks!

I learned Python after working professionally with several languages for many years, including Java and Delphi, and I can say that Python is *very* well designed, is implemented with the highest standards of software engineering and caters to a rigorous and expert audience. It is **extremely** unlikely that you will ever find a bug in the interpreter or the built-ins if you are using a released version of Python. I've been using Python professionally since 1998 and I never stumbled upon a single bug anywhere in a released Python distribution. Of course, there are bugs and even security hot-fixes are issued from time to time. But I've never been affected by a Python bug in my projects. So it's better to assume that any strange behaviour is actually some misunderstanding on your part than a bug.

You've got a couple of options on Windows, actually (not including
any roll-you-own or ported cron efforts). You can either use the
AT command (from the command line or via WMI) or you can use the
Windows scheduler, either from the control panel or programatically
via the win32com.taskscheduler module from pywin32.

The equivalent expression is In [1]: (2 in [1,2,3]) and ([1,2,3]==False) Out[1]: False 'in' is considered a comparison operator and can be chained with other comparisons. For a clearer example, consider In [2]: 2 < 3 < 4 Out[2]: True which is not the same as In [3]: 2 < (3 < 4) Out[3]: False or In [4]: (2 < 3) < 4 Out[4]: True It is equivalent to In [5]: (2 < 3) and (3 < 4) Out[5]: True See http://docs.python.org/ref/comparisons.html Kent ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

I don't know what it is on Windows though.

Sidestepping slightly, the natural way to open a URL using
whatever's set up to do so is with os.startfile:
import os
os.startfile ("http://whatever...ram";)
I was going to say that, to use IE7 explicitly, you should
use the webbrowser module. But then I realised that, for
reasons which I'm sure are extremely good but which elude
me for now, iexplorer is not one of the registered browsers.
As a fallback, you can look for its apppath entry in the registry
and use subprocess to call that.

[Tutor] comparison bug in python (or do I not get it?)
Dear Python folks, here is a sequence of commands (ipython) that lead to a question. See my comments after leading '#': In [1]: 2 in [1,2,3] Out[1]: True #nothing special here, of course 2 is in the list. In [2]: 2 in [1,2,3] == True Out[2]: False #This is somewhat surprising, as one would hope that '2 in [1,2,3]' #evaluates to 'True', and then we expect 'True'=='True' to hold. #However, maybe it is an issue of operator precedence. Let's add parenthesis: In [3]: (2 in [1,2,3]) == True Out[3]: True #Okay, so this does what we expect. #However, if it is an issue of operator precedence, then what is the #operation that is carried out at prompt [2] above? # #Presumably, we work out In [4]: [1,2,3] == True Out[4]: False #which is false. So effectively, The statement at [2] seems to boil down to In [5]: 2 in False --- exceptions.TypeError Traceback (most recent call last) /Volumes/Minmax250a/Users2/fangohr/ TypeError: iterable argument required But this throws an error! And so does the full expression (with paranthesis): In [6]: 2 in ([1,2,3] == True) --- exceptions.TypeError Traceback (most recent call last) /Volumes/Minmax250a/Users2/fangohr/ TypeError: iterable argument required So what is the story here? In my view, the statement in line [2] should either produce True (as in [3]), or throw an error (as in [6]). Why does [2] return False? Would people agree that this is a bug?

[Tutor] How to open IE7 to a certain URL?
I keep missing a certain weekly program on my local NPR station. My
idea is to record it using software I have, Easy Hi-Q Recorder. I can
set it to start recording when the program starts, 8pm, but I need to
have the program playing on my computer. The URL for the station's
audio is http://www.kuow.org/real.ram .
I've got this so far:
#!/usr/bin/env python
#coding=utf-8
import time
b = '20:00:00'
while True:
a = time.strftime('%H:%M:%S')
time.sleep(0.5)
if a == b:
print "TIME!"
break
Obviously, I need to replace the 'print "TIME"' line with something
that will open IE7 to http://www.kuow.org/real.ram . But what?
Thanks,
Dick Moores
