Frequently Asked Questions¶
Under Which Version of Python Should I Install Bandit?¶
The answer to this question depends on the project(s) you will be running Bandit against. If your project is only compatible with Python 3.8, you should install Bandit to run under Python 3.8. If your project is only compatible with Python 3.9, then use 3.9 respectively. If your project supports both, you could run Bandit with both versions but you don’t have to.
Bandit uses the ast module from Python’s standard library in order to analyze your Python code. The ast module is only able to parse Python code that is valid in the version of the interpreter from which it is imported. In other words, if you try to use Python 2.7’s ast module to parse code written for 3.5 that uses, for example, yield from with asyncio, then you’ll have syntax errors that will prevent Bandit from working properly. Alternatively, if you are relying on 2.7’s octal notation of 0777 then you’ll have a syntax error if you run Bandit on 3.x.
