With this EAP you are no longer limited to the PyPI repository. To manage the packages across various Python interpreters go to the Python interpreter settings ( Preferences | Settings / Python Interpreter). Note that all this will be performed for the currently selected Python interpreter. You can preview installed packages, update them, install new ones or uninstall them via the Python Packages tool window. At any time you can open it using the main menu: View | Tool Windows | Python Packages. This window is enabled by default, and you can find it in the lower group of the tool windows. In P圜harm 2021.1 we implemented the Python Packages tool window to provide you with the quickest and neatest way to preview and install packages for the currently selected Python interpreter. Python Packages Tool Window: install packages from custom locations Now, inspections like Unused local symbols and Unreachable code work for pattern matching cases.įor all PEPs and Python versions, visit the dedicated page. We are still working on making it fully-fledged. In the previous EAP, we announced initial support for structural pattern matching ( PEP 634, PEP 635, PEP 636). Inspection and a quick fix to switch to the old-style syntax in earlier Python versions.Please note that this import works only for annotations, not on runtime inside isinstance/issubclass. The from _future_ import annotations is recognized so that you can use the new syntax even with earlier versions of Python.Type inference for union types for isinstance and issubclass arguments, using the new syntax.See quick information by placing the caret at the symbol, and press F1 ( View | Quick Documentation). The new syntax is supported in P圜harm Quick Documentation.Overall code insight for new syntax, including intention actions. So what exactly is now supported in P圜harm? Mypy recently added support for this style of annotation in their v0.800 release, so it is a good time to try it out with the newly added P圜harm code assistance. This functionality is already available in earlier versions of Python with from _future_ import annotations. It added a special operator type._or_() that allowed writing int | str instead of Union. This PEP was aimed to tackle the syntax verbosity of the current union type. In this release, we added support for PEP 604 “Allow writing union types as X | Y”. You can also manually download the EAP builds from our website.ĭOWNLOAD PYCHARM 2021.2 EAP Python 3.10 New syntax for union types The Toolbox App is the easiest way to get the EAP builds and keep both your stable and EAP versions up to date. Important! P圜harm EAP builds are not fully tested and might be unstable. You can do this on Twitter (mentioning or on our issue tracker. We are hoping to get your active feedback on the overall performance of the P圜harm 2021.2 EAP versions, and in particular, on the feel, look, and performance of the new features we will be highlighting throughout the EAP blog posts. If you have not yet logged in, the IDE will redirect you to where you can enter your login and password or create a new JetBrains account.Īs usual, our main goal for the EAP is to give you a sense of what to expect in the upcoming P圜harm 2021.2 release. If you have already logged in with your credentials, you can access the EAP builds automatically. Starting with this EAP, you can join the program in P圜harm Professional only if you have an active JetBrains account. Take a look at what we have new in store for Python 3.10 support, easy package installation, work with JavaScript and TypeScript, and the debugger. The second EAP of P圜harm 2021.2 brings a lot of improvements, both platform-wide and Python-specific.
