[issue13718] Format Specification Mini-Language does not accept comma for percent value

[Michael Kesper]

New submission from Michael Kesper :

http://docs.python.org/library/string.html#format-specification-mini-language 
mentions:
Changed in version 2.7: Added the ',' option (see also PEP 378).

PEP 378 tells me:
The ',' option is defined as shown above for types 'd', 'e', 'f', 'g', 'E', 
'G', '%', 'F' and ''.

However:

Python 2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit (Intel)] on win
32
Type "help", "copyright", "credits" or "license" for more information.
>>> '{:.2,%}'.format(.537568)
Traceback (most recent call last):
  File "", line 1, in 
ValueError: Invalid conversion specification
>>> '{:2,%}'.format(.537568)
'53.756800%'

New submission from Michael Kesper :

In http://docs.python.org/library/stdtypes.html#mutable-sequence-types
s.pop([i]) is listed. Correct would be:
s.pop(i)

[issue5291] Windows upgrade to 2.6.1 requires 2.6 installer to be present

[Michael Kesper]

New submission from Michael Kesper :

When upgrading to 2.6.1, an error occurs if the old installer is not
found. I needed to open it several times until I read _what_ was needed.
Finding old installers on python.org requires too much search, too.

Now that you remind me, I remember having deleted some uninstall folders 
because the machine did not have any free disk space at that time.
Can possibly be closed. Thank you!

Best wishes

[issue29390] Python Tutorial should introduce iterators and generators

[Michael Kesper]

New submission from Michael Kesper:

Please look at 
http://stackoverflow.com/questions/41932287/how-can-i-create-a-loop-for-these-if-statements/41932494?noredirect=1#41932494
 

For beginners, it would be good to introduce the concepts of 'pythonic' dealing 
with sequences (iterators) and streams (generators) as soon as possible and 
everywhere where sequenceable data structures are discussed.

It is a common idiom in other languages to access members of sequences with 
counters, risking off-by-one errors or IndexErrors.

If beginners aren't introduced to the 'right' concepts soon enough, they might 
have a hard time figuring out the 'iterator' way.
Iterators should at least be mentioned in 
https://docs.python.org/3/tutorial/datastructures.html#looping-techniques.

[issue23241] shutil should accept pathlib types

[Michael Kesper]

New submission from Michael Kesper:

source_path = Path('../data')
destination_path = Path('//file_server/work/whatever')
for file_name in source_path.glob('xyz-*'):
shutil.copyfile(source_path / file_name, destination_path / file_name)

leads to:

Traceback (most recent call last):
  File "copy_shares_2_work.py", line 9, in 
shutil.copyfile(source_path / file_name, destination_path / file_name)
  File "C:\Python34\lib\shutil.py", line 90, in copyfile
if _samefile(src, dst):
  File "C:\Python34\lib\shutil.py", line 75, in _samefile
return os.path.samefile(src, dst)
  File "C:\Python34\lib\genericpath.py", line 90, in samefile
s1 = os.stat(f1)
TypeError: argument should be string, bytes or integer, not WindowsPath

Converting to str() works but is unexpected.
