With the following:
##
import email.message
m = email.message.EmailMessage()
m['Subject'] = 'Übung'
m.set_content('Dies ist eine Übung')
print('== cte: default == \n')
print(m)
print('-- full mail ---')
print(m)
print('-- just content--')
print(m.get_content())
m.set_content('Dies ist eine Übung', cte='quoted-printable')
print('== cte: quoted-printable ==\n')
print('-- full mail --')
print(m)
print('-- just content --')
print(m.get_content())
##
I get the following output:
##
== cte: default ==
Subject: Übung
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: base64
MIME-Version: 1.0
RGllcyBpc3QgZWluZSDDnGJ1bmcK
-- full mail ---
Subject: Übung
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: base64
MIME-Version: 1.0
RGllcyBpc3QgZWluZSDDnGJ1bmcK
-- just content--
Dies ist eine Übung
== cte: quoted-printable ==
-- full mail --
Subject: Übung
MIME-Version: 1.0
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: quoted-printable
Dies ist eine =C3=9Cbung
-- just content --
Dies ist eine Übung
##
So in both cases the subject is fine, but it is unclear to me how to
print the body. Or rather, I know how to print the body OK, but I don't
know how to print the headers separately - there seems to be nothing
like 'get_headers()'. I can use 'get('Subject) etc. and reconstruct the
headers, but that seems a little clunky.

TkInter Scrolled Listbox class?
Hi, I would like to build a class ScrolledListbox, which can be packed somewhere in ttk.Frames. What I did is to build not really a scrolled Listbox but a Frame containing a Listbox and a Scrollbar: class FrameScrolledListbox(ttk.Frame): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) # # build Listbox and Scrollbar self.Listbox = tk.Listbox(self) self.Scrollbar = ttk.Scrollbar(self) # # configure these two self.Listbox.config(yscrollcommand=self.Scrollbar.set) self.Scrollbar.config(command=self.Listbox.yview) # # pack them in Frame self.Listbox.pack(side=tk.LEFT, fill=tk.BOTH) self.Scrollbar.pack(side=tk.RIGHT, fill=tk.BOTH) That works, so instances of FrameScrolledListbox can be packed and the tk.Listbox itself is accessible via an attribute: frmScrolledListbox = FrameScrolledListbox(main) frmScrolledListbox.Listbox.config(...) But it would be a bit nicer to get a class like class ScrolledListbox(tk.Listbox): ... So it would be used that way: scrolledListbox = ScrolledListbox(main) scrolledListbox.config(...) Is that possible? The problem which I can't handle is to handle the Frame which seems to be needed to place the Scrollbar somewhere.

It's a great shame that Tix is gone, it had a lot of these useful widgets, but they were all wrappers around Tcl/Tk's Tix module and that is the thing that has gone. If you really want to replace it I'd suggest looking at the IDLE code and see what they did because the IDLE settings dialogues have scrolled lists and the IDLE guys have probably done a decent job in building their widgets.

Possibly you want to do that with parameters in `__init__` also. Example: class FrameScrolledListbox(ttk.Frame): def __init__(self, *frame_args, *, height=None, jump=None, **frame_kw): super().__init__(*frame_args, **frame_kw) self.Listbox = tk.Listbox(self, height=height) self.Scrollbar = ttk.Scrollbar(self, jump=jump) def config(self, *a, **kw): return self.Listbox.config(*a, **kw) and so forth for the various listbox methods you want to proxy to the listbox itself. You could pass scroll specific methods to the scrollbar as well. Cheers, Cameron Simpson -- https://mail.python.org/mailman/listinfo/python-list

OK, so I can do:
##
if args.verbose:
for k in mail.keys():
print(f"{k}: {mail.get(k)}")
print('')
print(mail.get_content())
##
prints what I want and is not wildly clunky, but I am a little surprised
that I can't get a string representation of the whole email in one go.

Sorry, I am confusing the terminology here. The 'body' seems to be the
headers plus the 'content'. So I can print the *content* without the
headers OK, but I can't easily print all the headers separately. If
just print the body, i.e. headers plus content, the umlauts in the
content are not resolved.
