Re: [web2py] web2py scripts (homemade task queues) and python2 compatibility
Hi Nico,
I tried explicitly with python2.7, by executing:
python2.7 web2py.py -S examples -M -R
applications/examples/private/script01.py
On a fresh downloaded version of web2py.
Same result.
In web2py/gluon/shell.py, I notice the following first line:
from __future__ import print_function
Funny enough, it's only trough an external script that I'm getting this
error.
Using the print statement in a controller function, everything works as
expected.
So I believe it's only when running an 'external' script
through web2py/gluon/shell.py that the print() function must be used.
Or am I missing something/making a mistake?
Best, Tom.

Re: [web2py] web2py scripts (homemade task queues) and python2 compatibility
Hi Tom,
even the latest 2.18.5 version of web2py is still fully compatible with
Python 2.7.
I think you're running both of your tests with python 3 ;-)
Another possibility is that you've first run your web2py framework with
python 3 and then with python 2 - you cannot mix them without cleaning up
caches and dbs... Try test02 a fresh copy of the web2py sources, after
being sure to use python2!

[web2py] web2py scripts (homemade task queues) and python2 compatibility
Can anyone confirm that backward compatibility with python2 is broken with
respect to web2py scripts (or homemade task queueus)?
I just downloaded version "2.18.5-stable+timestamp.2019.04.08.04.22.03" and
it looks like the python3 print() function must be used.
Is there any plan to fix this? If not, it would be good to include this
information in the web2py book.
Test01:
=
script "applications/examples/scrips/script01.py" containing only one line:
print("Test print")
This one executes fine when running:
python web2py.py -S examples -M -R applications/examples/scrips/script01.py
Test02:
==
script "applications/examples/scrips/script01.py" containing only one line:
print "Test print"
This one fails fine when running:
python web2py.py -S examples -M -R applications/examples/scrips/script01.py
Traceback (most recent call last):
File "/home/tclerckx/Downloads/web2py/gluon/shell.py", line 275, in run
execfile(startfile, _env)
File "applications/examples/scrips/script01.py", line 1
print "Test print"
