flake8-blind-except
|
|
===================
|
|
|
|
A flake8 extension that checks for blind, catch-all ``except:`` statements.
|
|
|
|
Using ``except`` without explicitly specifying which exceptions to catch is generally considered bad practice, since it catches system signals like ``SIGINT``. You probably want to handle system interrupts differently than exceptions occuring in your code.
|
|
|
|
It's also usually better style to have many small ``try``-``except`` blocks catching specific exceptions instead of a giant ``try:`` block with a catch-all ``except:`` at the bottom. It's also nicer to your fellow programmers to be a bit more specific about what exceptions they can expect in specific parts of the code, and what the proper course of action is when they occur.
|
|
|
|
An example of code that will fail this check is:
|
|
|
|
.. code-block:: python
|
|
|
|
try:
|
|
something_scary()
|
|
except:
|
|
everybody_panic()
|
|
|
|
However, the following code is valid:
|
|
|
|
.. code-block:: python
|
|
|
|
try:
|
|
something_terrifying()
|
|
except TerrifyingException:
|
|
dont_panic()
|
|
|
|
Installation
|
|
------------
|
|
|
|
If you don't already have it, install ``flake8``::
|
|
|
|
$ pip install flake8
|
|
|
|
Then, install the extension::
|
|
|
|
$ pip install flake8-blind-except
|
|
|
|
Usage
|
|
-----
|
|
|
|
Run the following to verify that the plugin has been installed correctly::
|
|
|
|
$ flake8 --version
|
|
2.0 (pep8: 1.4.6, flake8-blind-except: 0.1.0, pyflakes: 0.7.3)
|
|
|
|
Now, when you run ``flake8``, the plugin will automatically be used.
|
|
|
|
When a blind except is found, ``flake8`` will output::
|
|
|
|
B901 blind except: statement
|
|
|

Notes
|
|
-----
|
|
|
|
I've tested this package with flake8 2.6.2 and Python 2.7.3. It is untested (but likely compatible) with other software versions.
