Apparently, a Python version 3 interpreter is used but it finds a Python version 2 library. Those versions cannot mix. I cannot tell you how this mix came into being. I would try to uninstall Python and then reinstall freshly Python 3. -- https://mail.python.org/mailman/listinfo/python-list
CheetahTemplate 3.2.5
Hello!
I'm pleased to announce version 3.2.5, a minor feature release
of branch 3.2 of CheetahTemplate3.
What's new in CheetahTemplate3
==
The contributor for this release is Yegor Yefremov.
Build:
- Install ``Cheetah3`` + ``markdown`` (used in ``Cheetah.Filters``)
using ``pip install cheetah3[filters]`` (or ``cheetah3[markdown]``).
CI:
- Run tests with Python 3.8 at Travis CI.
What is CheetahTemplate3
Cheetah3 is a free and open source template engine.
It's a fork of the original CheetahTemplate library.
Python 2.7 or 3.4+ is required.
Where is CheetahTemplate3

Example
===
Below is a simple example of some Cheetah code, as you can see it's practically
Python. You can import, inherit and define methods just like in a regular Python
module, since that's what your Cheetah templates are compiled to :) ::
#from Cheetah.Template import Template
#extends Template
#set $people = [{'name' : 'Tom', 'mood' : 'Happy'}, {'name' : 'Dick',
'mood' : 'Sad'}, {'name' : 'Harry', 'mood' :
'Hairy'}]
How are you feeling?
#for $person in $people
$person['name'] is $person['mood']
#end for
Oleg.

I mean I've already made and tested a patch it wasn't hard. I did same day as I made the post. I've also done a bit of work on the proposal to make the key function changeable in functools.lru_cache though that is a bit more complex and will take a bit of refactoring to do right. -- https://mail.python.org/mailman/listinfo/python-list
OT: ALGOL 60 at 60
ALGOL 60 at 60: The greatest computer language you've never used and grandaddy of the programming family tree Back to the time when tape was king By Richard Speed 15 May 2020 at 09:47 https://www.theregister.co.uk/2020/05/15/algol_60_at_60/ NB 'El Reg' is known for its irreverent and cynical views of computing, poking-fun at every opportunity and using British-slang (which may challenge some - one way or another). I've often surmised reminders of ALGOL in Python. However, I had not previously remembered the ALGOL Bulletins and their similarity to Python's PEPs. ALGOL was almost 'the machine language' for the Burroughs B6700 series (and similar) but concurring with the article, we regarded it as somewhat academic and majored in FORTRAN, COBOL, or both. (as distinct from those who defined ComSc as compiler writing, for whom ALGOL was a brilliant tool!) The article also managed to elicit an "oh wow" from me, with its picture of a drum-plotter - few today will have seen a plotter that moves the paper as well as the pen (even if that's still the way most 'character-printers' work).

ALGOL was the third programming language I learned after FORTRAN and Assembly on the Bendix G-20 in early 1966. I first learned ALGOL on G.E. time sharing, where input was paper tape, although it didn't require loading the compilers from tape so I never hat that pleasure. I loved the block structure of ALGOL, and started indenting FORTRAN so that the program logic stood out even if FORTRAN didn't understand it. ... >ALGOL was almost 'the machine language' for the Burroughs B6700 series (and >similar) but concurring with the article, we regarded it as somewhat academic >and majored in FORTRAN, COBOL, or both. (as distinct from those who defined >ComSc as compiler writing, for whom ALGOL was a brilliant tool!) I really got into ALGOL on a time sharing system using the Burroughs B-5500 where ALGOL was the system's native language, there was no Assembly Language per-se. The OS MCP, (Master Control Progam) was written entirely in ALGOL. The FORTRAN compiler generated ALGOL source, and I learned a lot looking at the ALGOL output of the FORTRAN program. Many of the programming methods I use today have their roots in doing a lot of scientific programming in ALGOL on the B-5500, then in BPL (Burroughs Programming Language) on Burroughs Medium Systems, B-2500->B-4500.
