It's astounding to me that there is no way to get `pylint` or `flake8` to not try to follow a conditional import which is known to be incompatible with the version of Python currently running those linters.

This

try:

    import package.py2

except SyntaxError:

    import package.py3

or this

import sys

if sys.version_info < (3,):

    import package.py2

else:

    import package.py3

are perfectly good patterns for making portable code which also does not require `exec` or `eval`.

This is much more preferable. It keeps each version of the implementation

exposed to IDEs and linters which support that language version, instead of hiding them in programmatically opaque strings, and

looking like normal, clean, straightforward, and idiomatic code for humans.

And yet in both of these cases and any other variant I have been able to think of which did not involve putting `exec` or `eval` into the per-version files, `pylint` and `flake8` try to import both files and get syntax errors.

I get that resolving whether a conditional import applies is hard. Equivalent to the halting problem and may use information impossible to know during linting. Even the provable and simple cases would take effort to code. So it is reasonable to lint all imports, even conditional ones.

But this is well within the checking those linters already implement. Trivial, reliable heuristic. Especially the top variant, a one-liner import within a try block that catches precisely syntax errors.

And this is obviously a nicer way to handle syntax portability issues than `exec` or `eval`, when all the best practices at balanced in.

Pylint Errata

Some notes on runing pylint under VisualStudio Code. Normally pylint looks for a pylintrc file in package path of the file being linted. But with the Python extension in VS Code this doesn’t happen. You have to place your pylintrc file in the root folder of your workspace. And if it isn’t the same as the root package of your python package tree linting won’t use your preferences.

Pylint is a Python source code analyzer which looks for programming errors, helps enforcing a coding standard and sniffs for some code smells (as defined in Martin Fowler’s Refactoring book).

Pylint has many rules enabled by default, way too much to silence them all on a minimally sized program. It’s highly configurable and handle pragmas to control it from within your code. Additionally, it is possible to write plugins to add your own checks.

PyLint, PyChecker or PyFlakes?

I would like to get some feedback on these tools on :

features;

adaptability;

ease of use and learning curve.

Answer: PyLint, PyChecker or PyFlakes?

Well, I am a bit curious, so I just tested the 3 myself right after asking the question ;-)

Ok, this is not a very serious review but here is what I can say :

Are there any static analysis tools for Python?

I am starting to use Python (specifically because of Django) and I would like to remove the burden for exhaustive testing by performing some static analysis. What tools/parameters/etc. exist to detect issues at compile time that would otherwise show up during runtime? (type errors are probably the most obvious case of this, but undefined variables…
