Hello Python developers,
Python analysis has been upgraded to detect bugs that make your application crash with KeyError or IndexError exceptions.
The 3 added rules are:
- S6464: Non existent dictionary keys should not be accessed
- S6465: Unpacking should have the same number of elements of the iterable
- S6466: Accessing list elements should not trigger an IndexError
Here is an example of a mistake that can be detected with such rules:
server_platform doesn’t exist in the
certificate dictionary and we’ll lead to a KeyError if the condition on line 473 is true.
These rules are available now on SonarCloud.io and will be part of SonarQube 9.8.
