I noticed when trying out Python's 2.6b2 release that the repr of

double quotes were used whereas on 2.6b2:

>>import decimal

single quotes are used. Searching around I see this was done in r60773
with the log message:
Fix decimal repr which should have used single quotes like other reprs.
but I can't find any discussion other than that.
My problem is this breaks a bunch of doctests that were written assuming
the prior repr. I can't just update the tests to assume the new single
quotes because they are for code that is supposed to run on everything
back to Python 2.3.
So my question:
Is this backwards-incompatible change really necessary and could it be
reconsidered?
If it's here to stay, is there some straightforward why that I am
unaware of to construct tests that use Decimal repr but will work
correctly on Python 2.3-2.6?
Also, if this is not the right list for this question please let me know
where would be more appropriate and I will go there.
If answers here do not satisfy, the pydev list would be the place to
request that this change be put off until 3.0, when changes that break
are more permissible. I do not remember any discussion of this issue.

Dear All,
I need a way of writing strings or arbitrary Python code that will
a) allow the strings to be read again unchanged (like repr)
b) write multiline strings as multiline strings instead of escaping the
\n's.
A repr function that output triple-quoted strings with explicit
(non-escaped) linebreaks would be perfect.

Suggestions and all kinds of recomendations are more than welcomed.
If it all goes ok, it'll be a PEP when I finish writing/modifying the code.
Thank you.

I wonder why this expression works:

but this one causes an error

Sorry to ask a Perl question here, but... Does Perl have something like
Python's repr() function? I want to print out a string and have CR print as
\r, LF as \n, etc. I looked in the Perl/Python phrasebook:
http://wiki.python.org/moin/PerlPhrasebook
but saw nothing along those lines.
Thx,

I understand that idea of an object's __repr__ method is to return a
string representation that can then be eval()'d back to life, but it
seems to me that it doesn't always work.
For example it doesn't work for instances of the object class:
In : eval(repr(object()))
------------------------------------------------------------
File "<string>", line 1
<object object at 0xf233e8>

Was looking at PEP 3108, http://www.python.org/dev/peps/pep-3108/ ,
and saw that the repr module was slated for vaporization. I've only
used the module a few times ever. I'm curious if the community wants
it kept around or whether it is considered clutter.
The PEP is going to be finalized soon, so if you have issues with it,
they should be sent to the PEP author or brought up on the list,...

I've been saving data in a file with one line per field.
Now some of the fields may become multi-line strings...
I was about to start escaping and unescaping linefeeds
by hand, when I realized that repr() and eval() should
do. Hence the question: If s is a string, is repr(s)
guaranteed not to contain line breaks?

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
