The xml.etree.ElementTree.ElementTree() can accept lxml.etree.Element() as a
node, but node in node is impossible.

[issue28237] In xml.etree.ElementTree bytes tag or attributes raises on serialization
New submission from py.user:
https://docs.python.org/3/library/xml.etree.elementtree.html#xml.etree.ElementTree.Element
"The element name, attribute names, and attribute values can be either
bytestrings or Unicode strings."
The element name, attribute names, and attribute values can have bytes type,
but they can't be serialized:

Also attribute name can be serialized, but it holds the letter "b" and single

And same try with site package lxml works fine for all cases because it
converts bytes to unicode strings right away:

>>> root
>>>
>>> elem = lxml.etree.SubElement(root, b'y', {b'a': b'b'})

[issue27992] In the argparse there is a misleading words about %(prog)s value
New submission from py.user:
https://docs.python.org/3/library/argparse.html#argumentparser-objects
"prog - The name of the program (default: sys.argv[0])"
It doesn't take all sys.argv[0]. It splits sys.argv[0] and takes only the
trailing part.
An example:
a.py
#!/usr/bin/env python3
import argparse
import sys
parser = argparse.ArgumentParser()
parser.add_argument("arg", help="The name is %(prog)s, the sys.argv[0] is " +
sys.argv[0])
args = parser.parse_args()
The output in the console:
[guest@localhost bugs]$ ../bugs/a.py -h
usage: a.py [-h] arg
positional arguments:
arg The name is a.py and sys.argv[0] is ../bugs/a.py
optional arguments:
-h, --help show this help message and exit
[guest@localhost bugs]$
In the output we see that %(prog)s takes only trailing part of sys.argv[0] not
all.
Applied a patch to the issue that specifies about part of sys.argv[0].

[issue27991] In the argparse howto there is a misleading sentence about store_true
New submission from py.user:
https://docs.python.org/3/howto/argparse.html#combining-positional-and-optional-arguments
"And, just like the “store_true” action, if you don’t specify the -v flag, that
flag is considered to have None value."
This sentence is misleading. It supposes that "store_true" action can save None
value. But "store_true" action always saves True or False value.
An example:
This code was taken from the argparse howto. I've just added the -f option and
printed args to the stdout.
a.py
#!/usr/bin/env python3
import argparse
parser = argparse.ArgumentParser()
parser.add_argument("square", type=int,
help="display the square of a given number")
parser.add_argument("-v", "--verbosity", action="count",
help="increase output verbosity")
parser.add_argument("-f", "--flag", action="store_true")
args = parser.parse_args()
print('args:', args)
The output in the console:
[guest@localhost bugs]$ ./a.py 1
args: Namespace(flag=False, square=1, verbosity=None)
[guest@localhost bugs]$
In the output we see that the -f option have got the False value not None.
Applied a patch to the issue that just removes words about analogy with
store_true action.

Actually, it behaves like a string, but the format should call internal format
function of the passed number and the internal format function should not
format different numbers as equal numbers.
Why does it represent number 1 as number 10?
>>> format(1, '<02')
'10'

'10'

I guess, there should be a restriction.
Zero padding for numbers should be correct.

[issue24477] In argparse subparser's option goes to parent parser
New submission from py.user:
Some misleading behaviour found with option belonging.
It's possible to put one option twicely, so it can set different
parameters accoding to context.
A source of argt.py for test:
#!/usr/bin/env python3
import argparse
parser = argparse.ArgumentParser()
parser.add_argument('-f', dest='tf', action='store_true')
subs = parser.add_subparsers()
sub = subs.add_parser('cmd')
sub.add_argument('-f', dest='cf', action='store_true')
parser.add_argument('arg')
args = parser.parse_args()
print(args)
Running it:
[guest@localhost debug]$ ./argt.py cmd 1
Namespace(arg='1', cf=False, tf=False)
[guest@localhost debug]$ ./argt.py cmd -f 1
Namespace(arg='1', cf=True, tf=False)
[guest@localhost debug]$ ./argt.py cmd 1 -f
Namespace(arg='1', cf=False, tf=True)
[guest@localhost debug]$
ISTM, options for the top parser should be placed between program name and
subcommand name in any order, and options for the subcommand should follow
subcommand in any order. The argument of top parser should be moved to the end
and parsed after all options were placed correctly.

py.user added the comment:
paul j3 wrote:
You can give the positional any custom name (the first parameter).
The dest argument is not required for giving name for an optional.
You can either make it automatically or set by dest, it's handy and clear.
import argparse

_ = parser.add_argument('-a', '--aa')
_ = parser.add_argument('-b', '--bb', dest='x')
args = parser.parse_args([])
print(args)
Namespace(aa=None, x=None)
But if you do the same thing with a positional, it throws an exception. Why?
(I'm a UNIX user and waiting predictable behaviour.)
And the situation with another action (not only append_const, but future
extensions) shows that dest may be required.

It's not very useful to print empty choices, but the choices list could be
formed dynamically. So the command-line user can't figure out what's happen.

New submission from py.user:
A script, configuring argparse to have no choices:

Running it:

[issue24419] In argparse action append_const doesn't work for positional arguments
New submission from py.user:
Action append_const works for options:
import argparse
parser = argparse.ArgumentParser()
_ = parser.add_argument('--foo', dest='x', action='append_const', const=42)
_ = parser.add_argument('--bar', dest='x', action='append_const', const=43)
parser.parse_args('--foo --bar'.split())
Namespace(x=[42, 43])
Action append_const works for single positionals:
import argparse
parser = argparse.ArgumentParser()
_ = parser.add_argument('foo', action='append_const', const=42)
_ = parser.add_argument('bar', action='append_const', const=43)
parser.parse_args([])
Namespace(bar=[43], foo=[42])
Action append_const doesn't work for positionals in one list:
import argparse
parser = argparse.ArgumentParser()
_ = parser.add_argument('foo', dest='x', action='append_const', const=42)
Traceback (most recent call last):

The reason is that a positional argument can't accept dest:

parser = argparse.ArgumentParser()
parser.add_argument('foo', dest='x')

Ok.
What about inconsistent conversion dashes to underscores?

parser = argparse.ArgumentParser(prefix_chars='@')

_ = parser.add_argument('@@y-one-two-three@')

We set dash as non-option char, but it continues to convert to underscore while
another option char doesn't convert.

It depends on encoded part in the header, what email.header.decode_header()
returns.
If the header has both raw part and encoded part, the function returns (bytes,
None) for the raw part. But if the header has only raw part, the function
returns (str, None) for it.
import email.header
s = 'abc=?koi8-r?q?\xc1\xc2\xd7?='

[(b'abc', None), (b'\xc1\xc2\xd7', 'koi8-r')]

email.header.decode_header(s)

There should be (bytes, None) for both cases.

These are another cases. The first is very special. The second and third are
special too, but with different contents of assertion they can do useful work.
While (?=any contents){N}a never uses the {N} part in any useful manner.
So I think this report should be closed
I looked into Perl behaviour today, it works like Python. It's not an error
there.
