The problem:
1. there are various code inspection tools that parse Python programs looking
for style issues or whatnot. The deeper ones have to do a full parse of the
python program. It would be helpful if there were a uniform way to indicate the
Python language level used in Python source code.
2. I get a standalone python program that is not part of a package. vcprompt
https://bitbucket.org/gward/vcprompt might be an example
It would be helpful if there were an easy way to know what language version of
Python it assumes
Perl has something like called "use perl". "use" is roughly equivalent to
"import".
Possible solutions:
Do it the similar to "use perl". Here "perl" is a package that just tests the
parameter given it. In Python such the code would look something like
File/module python30.py
import sys
assert sys.version >= (sys.version_info >= (3, 0))
The above works, but to reduce proliferation of packages it might be preferable
to come up with some way to pass a version specification string similar to the
specification strings allowed in setup.py
A metadata tag as a comment in a docstring or in a comment.
Preferably this would be given towards the top of the file to make it easier
for tools to extract this information.
Thoughts?
I don't understand your assertion
Python 3.2.3 (default, Jun 18 2015, 21:46:42)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> assert sys.version >= (sys.version_info >= (3, 0))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: unorderable types: str() >= bool()
What you means ?
