I was wondering how the code completion of the PyCharm Python console works. The console enables executing Python code line by line. The lines are executed in the configured Python interpreter. OK, this is expected. But how does the code completion work?

Whenever the property "x" is called the message is printed. Getting code completion for "x" will execute the print statement. This can be confusing for the user, but is harmless compared to starting a long-running process or code which modifies the internal state.

Since my DataFrame viewer plugin also supports older versions of PyCharm, I took a look at the runtime code completion. Whenever the user triggers the code completion, the Python console fetches the required information from the Python interpreter.

Under the hood, PyCharm uses a collection of Python scripts to interact with the interpreter. In case of runtime code completion, the current code that needs to be completed is sent to a helper script. Depending on the context, the script extracts the information and returns it.

PyCharm offers runtime code completion and static code completion in the Python console. Static code completion was added in PyCharm 2023.2 and enabled as default in 2023.3.
