[Tutor] The name of the module
Dear Tutors, there was a thread some weeks ago about how can we find out what is the name of the current module, where the function was loaded from, where the function running from or so, with some magic. I can't find it in the archive. May someone help me with some reference about it ? Yours sincerely, __ János Juhász ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Then your source file is not really in UTF-8.
BTW you can simply say
raw = u"121ø 55' 5.55''"

Get an editor on Windows that can edit UTF-8 text files and file
transfer software that doesn't change the text encoding. Work with UTF-8
exclusively.

This really helped!

Thanks. This sounds really trivial but the thing is that one cannot define file
encoding in PythonWin.
I will have to either use a advanced editor like Notepad++ and run the script
via console or use Geany as IDE.
Since it didn't work in IPython as well I assume that I need to change the
encoding of the IPython shell to UTF-8, too. Still need to find out where.
The following code works on windows when saved to a UTF-8 encoded file:
# -*- coding: utf-8 -*-
# the file needs to be set to UTF-8 encoding if working on windows
from easygui import easygui
raw = unicode("125° 15' 5.55''", 'utf-8')
print raw.encode('utf-8')
lines = raw.split(unicode('°', 'utf-8'))
print lines
entertext = easygui.enterbox(message="Enter something.", title="",
argDefaultText=raw)
print entertext
degrees = lines[0]
print "degrees: ", str(degrees)
Thanks for your support, so far.

I'm sure there'll be lots of other suggestions, but the SciTE
editor (whose name I'm never sure how to prononunce without
blushing) understands the same encoding directive as Python.
It's quite lightweight, and also allows you to run Python scripts
directly, although there are limitations. Worth looking at, anyhow.

Really! That is surprising. Anyone else know how to set the file
encoding for the PythonWin editor?

Was the problem with the print statements? Maybe changing the console
encoding would help. I have some notes here:

Again, I think this can be simplified to
raw = u"125° 15' 5.55''"

Put a file called 'sitecustomize.py' into any directory on your PYTHONPATH.
write the folowing two lines in that file:
import sys
sys.setdefaultencoding('utf-8')
To test, start ipython and type
import sys
sys.getdefaultencoding()
It should be utf-9 now.
Again, may sound trivial. for some. But I started my Python adventures on Ubuntu
Linux which it set to UTF-8 as default encoding. Due to some software
environments I am currently forced to use Windows. After installing Python and
some modules with setup.exe I never new that I even have to care for this...

Just be aware that this affects portability of your scripts; they will
require this same change to run on other systems. For this reason you
might want to change the code instead. If you give a specific example of
what is failing I will try to help.

Amazing! No matter how much I think I know the landscape, there's always something which has escaped my attention. I notice it's GTK-based and I'm running on Win32 where GTK seems to be a bit clunky, but thanks for the heads-up nonetheless.

It does, but it's getting confusing when I compare the following:
>>> raw = u"125° 15' 5.55''"
125° 15' 5.55''
>>> print u"125° 15' 5.55''"
UnicodeEncodeError: 'ascii' codec can't encode characters in position
3-4: ordinal not in range(128)
>>> print u"125° 15' 5.55''".encode('utf-8')
125° 15' 5.55''
>>> print unicode("125° 15' 5.55''")
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position
3: ordinal not in range(128)
>>> print unicode("125° 15' 5.55''", 'utf-8')
UnicodeEncodeError: 'ascii' codec can't encode character u'\xb0' in
position 3: ordinal not in range(128)
So apart from the errors all being slightly different, is there
perhaps some difference between the str() and repr() functions (looks
like repr uses escape backslashes)?
Or does it simply have to do with my locale, which is set to the
default "C" (terminal = standard Mac OS X terminal, with UTF-8
encoding)? Although that wouldn't explain to me why the third
statement works.
And checking the default encoding inside the python cmdline, I see
that my sys module doesn't actually have a setdefaultencoding()
method; was that something that should have been properly configured
at compile time? The documentation mentions something about the site
module, but I can't find it there either.
Any enlightenment on this is welcome.

print must encode unicode strings. It tries to encode them using the
default encoding which doesnt' work because the source is not ascii.

That is the way to get it to work.

Here the problem is trying to create the unicode string using the
default encoding, again it doesn't work because the source contains
non-ascii characters.

This is the same as the first encode error.

The setdefaultencoding() function (it's not a method, it is a
module-level function) is removed from the sys module as part of startup
(I think by the site module). That is why you have to call it from
sitecustomize.py. You can also
reload(sys)
to restore it but it's better to write your app so it doesn't require
the default encoding to be changed.

This is the thing I don't get; or only partly: I'm sending a utf-8
encoded string to print. print apparently ignores that, and still
tries to print things using ascii encoding. If I'm correct in that
assessment, then why would print ignore that?

Ie, use encode('utf-8') where necessary?
But I did see some examples pass by using
import sys
sys.setdefaultencoding('utf-8')
??
Oh well, in general I tend to play long enough with things like this
that 1) I get it (script) working, and 2) I have a decent feeling
(90%) that I actually understand what is going on, and why other
things failed. Which is roughly where I am now ;-).

No, you are sending a unicode string to print.
unicode("125° 15' 5.55''", 'utf-8')
means the same as
"125° 15' 5.55''".decode('utf-8')
which is, "create a unicode string from this utf-8-encoded byte string".
Once you have decoded to Unicode it is no longer utf-8.

print just knows that you want to print a unicode string. stdout is
byte-oriented so the unicode chars have to be converted to a byte
stream. This is done by encoding with sys.getdefaultencoding(), i.e.
print unicode("125° 15' 5.55''", 'utf-8')
is the same as
print u"125° 15' 5.55''"
which is the same as
print u"125° 15' 5.55''".encode(sys.getdefaultencoding())
> Ie, use encode('utf-8') where necessary?
Yes.
> But I did see some examples pass by using

Yes, that will make the examples pass, it just isn't the recommended
solution.

The key thing is to realize that there are implicit conversions between
str and unicode and they will break if the data is not ascii. The best
fix is to make the conversions explicit by providing the correct encoding.

Re: [Tutor] String module; Count
You can only count one at a time.
count = conversion(n).count("0") + conversion(n).count("1")
count is a string method, so it operates directly on the string - you
don't have to call it like you did.
import string
string.count(mystr, "cheese")
is the same as
mystr.count("cheese")
At least it is in newer versions of python.
Let me know if that helped.

Work is work, but how is the 'mainframe technology' you are working under, boring? Why do you think a good scripting language will help the "boredom"? > so chose python...please give me link to a pdf > which is suitable for beginners. Why did you pick on Python? What did Python ever do to you? Lessee now... working under mainframe technology, but 'bored' with it, and looking for a good scripting language to help with the boredom H. Python is anything but boring!

Hi Bryan, Hve a look at the tutorial (on python.org) section on reading from files. You'll also need to read about string methods in the standard library (specifically, the split() method) and dictionaries (in the tutorial, again). If you get stuck, show us what you've tried and we'll try to help. -- John. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
