PyCharm intellisense for boto3
I was frustrated with the same issue. So I decided to parse boto3 documentation and generate wrapper classes from the documentation. Here is the link to project https://github.com/gehadshaat/pyboto3
To install it
pip install pyboto3
To use it
import boto3 s3 = boto3.client('s3') """ :type : pyboto3.s3 """ # s3. -> will give you autocomplete for s3 methods in pycharm
Make sure that you first:
- Install pyboto3 -> pip install pyboto3 | pip3.x install pyboto3
- Check your interpreter settings and verify that you see pyboto3 on the list
- Do a File -> Invalidate Caches/Restart
After Pycharm restarts you should see intellisense working in your favor and all of the available methods for the service (in the case above s3) you are trying to use available to you!
This is happening because all of the methods on the boto3 clients and resource objects are generated at runtime based on a JSON file that describes what operations the service supports. Pycharm would have to have specific knowledge about this process in order to auto complete method names.
For your second question, boto3 is the official AWS SDK for Python. One of the main advantages of boto3 is that because of this JSON model driven process that describes the AWS APIs, most new service features only require a simple model update. This means API updates happen in a quick, consistent, and reliable manner.
But if you're using boto in existing code and it's working for you, feel free to keep using it. You can always install boto3 along side boto if you need to pull in new functionality.
The room's getting a little crowded here, but I also have created a
boto3 typing solution (GitHub link),
boto3_type_annotations. I took the
pyboto3 approach and parsed the docstrings of service objects and then programmatically wrote class definitions for them and annotated arguments and return types with the
typing module. Unlike
pyboto3 I created everything including service resources, paginators, and waiters. There's also an option where I left the docstrings in, so PyCharm's quick documentation will work. But fair warning, that package is really big.
# Without docs pip install boto3_type_annotations # Or with docs pip install boto3_type_annotations_with_docs
