Mike,

Thank you.

I moved to Python 3 some time ago.  I confirm that Python 3 does not
have the problem.  But I can't conveniently verify your workaround for
Python 2.

Regards,

[issue25257] In subject line email library inserts unwanted space after a thousands comma in a number

2015-09-28 Thread Bob Hossley 

New submission from Bob Hossley:

In my function makeMsg(), there is:

msg = email.mime.nonmultipart.MIMENonMultipart('text',
'plain', charset='utf-8')
msg['Subject'] = email.header.Header(subject, 'utf-8')

subject has no space after the thousands comma:

u'1,010 words - "The Blackmail Caucus, a.k.a. the Republican Party" By Paul 
Krugman'


But

msg['Subject'].__str__()

'1, 010 words - "The Blackmail Caucus,\n a.k.a. the Republican Party" By Paul 
Krugman'

has a space after the thousands comma and the email message later generated has 
a space after the thousands comma.

This is objectionable.

Note that the email library also inserts a newline after the comma that is 
followed by a space.  Since I see no effect of this newline on the email 
generated, I have no objection to the newline.

Thank you R. David Murray.

I look forward to being able to move my application to Python 3.

[issue24949] Identifier lookup in a multi-level package is flakey

2015-08-31 Thread Bob Hossley 

Bob Hossley added the comment:

msg<249269>

Thank you David Murray.

I should have asked myself, what is reasonable behavior?  In the case of 
email.mime.nonmultipart an explicit import is clearly needed.

I was misled by my experience with the os library.  As a "package" it is very 
different from the email library.  Importing os also makes available all of 
what appear at the script syntax level to be all its "sub-packages."

Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> print(os.path.split)


In the future I will try to remember that the effects of importing a "package" 
depend on how the "package" is packaged.

So far as I'm concerned this issue is closed.

I doubt that symptom "flakey Python behavior" is serious enough to interest 
Canonical.

[issue24949] Identifier lookup in a multi-level package is flakey

2015-08-31 Thread Bob Hossley 

Bob Hossley added the comment:

msg249272

Thank you Martin Panter for the documentation URL's.  The import machinery is 
so complicated that I have given up trying to understand what is "correct" 
behavior.Depending on the code in the relevant __init__.py and/or 
explicitly referenced Python modules each Python library can have vastly 
different import behavior.  I believe the simplest way to figure out what an 
import does and hence, what import statements I need is to run a Python 
interpreter in a terminal, execute an import statement, and then use the dir() 
function several times to see what the import statement did.

The import documentation is only slightly useful due to its great length and 
complexity.

[issue24949] Identifier lookup in a multi-level package is flakey

2015-08-27 Thread Bob Hossley 

New submission from Bob Hossley:

This seems like a bug to me, but it may be a recognized limitation even though 
I couldn't find any documentation suggesting that my tests should not work 
reliably.  I see no reason why my tests should not work reliably.

I have reliably reproduced the flakeyness under Windows XP with Python 2.6.4 
and under Xubuntu 14.04 64-bit with Python 2.7.6 and Python 3.4.0.

Ubuntu 14.04 (trusty)  - XFCE desktop (Xubuntu) 64-bit
Gnome:  3.8.4
Kernel:  3.13.0-62-generic
GCC Version:  4.8 (x86_64-linux-gnu)
Xorg Version:  1.15.1 (12 February 2015  02:49:29PM)

Rebooting doesn't help.

I first encountered the flakeyness in a complicated script which I will 
describe in outline first.  The very, very simple interactive Python sessions 
that follow are probably of more interest and use to you.
---
Outline of my complicated script:

import email

# The next line works around a flakeyness in Python
from email.mime.nonmultipart import MIMENonMultipart

msg = email.mime.nonmultipart.MIMENonMultipart('text', 'plain', 
charset='utf-8')

Without the above work around I always get Error:

AttributeError: 'module' object has no attribute 'nonmultipart'

Note import email is global.  from email.mime.nonmultipart import 
MIMENonMultipart is local to the function containing the msg =  line which 
is the line that fails whenever the workaround is absent.
