[issue14677] Python 2.6 Printing Error

[mesheb82]

New submission from mesheb82 :

I’m running:
Python 2.6.2 (r262:71605, Apr 14 2009, 22:40:02) [MSC v.1500 32 bit (Intel)] on 
win32

I was testing out some print functionality and I made an error in typing (I 
meant to use %8.8f), but is this behavior intentional or is it an error?
>> print '%8.8s' %(101.)
>> '1000'


I would expect this to return a TypeError.

I also tested this on Python 2.4 and Python 2.5 on linux and had the same 
behavior.

Steve

[issue14897] struct.pack raises unexpected error message

[mesheb82]

New submission from mesheb82 :

I found some unexpected behavior while working with the struct module.
>>> import struct

This works as expected:
>>> struct.pack('1s1s','3','4')
'34'

In this case, with bad input, the error message says I need 2 arguments, when I 
provide 2 arguments.
>>> struct.pack('1s1s','33')
Traceback (most recent call last):
  File "", line 1, in 
struct.error: pack requires exactly 2 arguments

Also, I tested this on Windows in Python 3.2.3 and Windows in Python 2.7.2

I got unexpected results when working with a string that has an apostrophe in 
it.
"Joe's".title()

[issue29628] struct objects can no longer be pickled

[mesheb82]

New submission from mesheb82:

When I run the following code on Windows/Linux for < Python 3.6, I have no 
problems.  When I run in Python 3.6.0, I get the subsequent traceback.

I checked the release notes and only saw the following struct module note 
related to half-floats: Issue #11734

from struct import Struct
import copy
this_fails = Struct('
copy.deepcopy(this_fails)
  File "F:\Anaconda\envs\py36\lib\copy.py", line 169, in deepcopy
rv = reductor(4)
TypeError: can't pickle Struct objects


To be clear, I'm copying struct objects as part of a larger class.  As I'm 
running many function calls where I create the same struct objects, saving the 
common struct objects allows me to get a factor of 2x speedup on my code.  
Deleting the saved struct objects at the end of file reading (and before the 
deepcopy takes place) fixes the problem.

[issue30906] os.path.join misjoins paths

[mesheb82]

New submission from mesheb82:

I'm trying to join paths on Windows with data taken from a user generated file. 
 In doing so, I came across:

>>> os.path.join('dir1', '/dir2')
'/dir2'

I'd expect an error or:

'dir1\\dir2'

This has been tested and is consistent with Python 2.7.13 and 3.6.1.

[issue30906] os.path.join misjoins paths

[mesheb82]

mesheb82 added the comment:

Testing on Python 2.7.12 on through Windows 10 bash (so Linux), I find an 
inconsistency with the documented statement "If a component is an absolute 
path, all previous components are thrown away and joining continues from the 
absolute path component"

>>> os.path.join('dir', 'C:/dir2')
'dir/C:/dir2'

To me, the is very similar to the original problem (Windows 10 Python 2.7.13 
and 3.6.1):

>>> os.path.join('dir1', '/dir2')
'/dir2'

I would argue that on Windows, '/dir2' is not an absolute path.  Testing from 
cmd and powershell on Windows 10 from `C:`
>>> cd /dir2
C:/dir2

I do agree though that is a terrible idea to not respect the second parameter 
in:
os.path.join(absolute_path_or_local_path, absolute_path)

I think the question is what is considered an absolute path and does that 
change depending on the OS?
