Key features of PyCharm 2024.3

AI Assistant

Inline AI prompting

Get help with code, generate documentation, or write tests by prompting AI directly in PyCharm’s editor. Just type your request on a new line and hit Enter.

Edits made by AI are marked in purple in the gutter, so changes are easy to spot. Need a fresh suggestion? Press Tab, Ctrl+/ ( ⌘/ on macOS), or manually edit the purple input text yourself. This feature is available for Python, JavaScript, TypeScript, JSON, YAML, and Jupyter notebooks.

For a personalized AI chat experience, you can now also choose from Google Gemini, OpenAI, or your own local models. Moreover, enhanced context management now lets you control what AI Assistant takes into consideration. The brand-new UI auto-includes open files and selected code and comes with options to add or remove files and attach project-wide instructions to guide responses across your codebase.

Ability to convert for loops into list comprehensions

Refactor your code faster with AI Assistant, which can now help you change massive for loops into list comprehensions. This feature works for all for loops, including nested and while loops.

Local multiline AI code completion PyCharm Professional

PyCharm Professional now provides local multiline AI code completion suggestions based on the proprietary JetBrains ML model used for Full Line Code Completion. Note that we don’t use your data to train the model.

Local multiline code completion typically generates 2–4 lines of code in scenarios where it can predict the next sequence of logical steps, such as within loops, when handling conditions, or when completing common code patterns and boilerplate sections.

Coding assistance for the dataclass_transform decorator (PEP 681)

PyCharm now supports intelligent coding assistance for custom data classes created with libraries using the dataclass_transform decorator. Enjoy the same support as for standard data classes, including attribute code completion and type inference for constructor signatures.

Jupyter Notebook PyCharm Professional

Auto-installation for multiple packages 

PyCharm 2024.3 makes it easier to install packages that are imported in your code. A new quick-fix is available for bulk auto-installations, allowing you to download and install several packages in one click.

Ability to open Jupyter table outputs in the Data View window

View Jupyter table outputs in the Data View tool window to access powerful features like heatmaps, formatting, slicing, and AI functions for enhanced dataframe analysis. Just click on the Open in Data View icon to get started. 

No-code data filtering 

Effortlessly filter data in the Data View tool window or within dataframes without writing any code. Just click the Filter icon in the upper-right corner, choose your filter options and see results in the same window. This functionality works with all supported Python frameworks, including pandas, Polars, NumPy, PyTorch, TensorFlow, and Hugging Face Datasets.

Debug port specification PyCharm Professional

PyCharm now allows you to specify a single debugger port for all communications, simplifying debugging in restricted environments like Docker or WSL. After you set the port in the debugger settings, the debugger runs as a server and all communication between it and the IDE flows through the specified port.
