PyCharm is a huge help when dealing with APIs that return huge or complicated data structures or where documentation is vague. Examples: interacting with AWS with boto3; interacting with Kubernetes.
You can read the docs alone, but much better is to set up a live interaction with the API. I set a breakpoint and explore the returned data structure in the debugger. All types and content are clearly visible and are a guide to the next iteration of the code's form.
