Sep 23, 2013 · A: PyPy isn't 100% compatible with CPython because it isn't simulating CPython under the hood. Some programs may still depend on CPython's unique features that are absent in PyPy such as C bindings, C implementations of Python object&methods, or the incremental nature of CPython's garbage collector.
3 days ago · Note also that our JIT has a very high warm-up cost, meaning that any program is slow at the beginning. If you want to compare the timings with CPython, even relatively simple programs need to run at least one second, preferably at least a few seconds. Large, complicated programs need even more time to warm-up the JIT.
Here's some news: gcc is available on Windows too! (CPython on Python takes advantage of gcc's label pointers to do faster bytecode dispatching using 'computed goto'. This is not supported by MSVC, so CPython on Windows is a little slower than it need be, because of a misconception.) I actually have an interpreter project of my own, for Windows.

There are several options for installing Python interpreters to work with Visual Studio. You can install an interpreter when you install the Python workload, or you can install an interpreter after a workload is present. Interpreters can also be installed manually outside of the Visual Studio Installer.
When you install the Python development workload in Visual Studio 2017 and later, Python 3 (64-bit) also installs by default. As an option, you can choose to install the 32-bit or 64-bit version of Python 2 or Python 3, along with Miniconda (Visual Studio 2019) or Anaconda 2/Anaconda 3 (Visual Studio 2017). The steps for this type of installation are described in Install Python support in Visual Studio.
An alternate approach is to install standard Python interpreters by using the Add Environment feature in Visual Studio. This option is available in the Python Environments window and the Python toolbar.
Python interpreters can also be installed manually outside of the Visual Studio Installer. Suppose you install Anaconda 3 before you install Visual Studio. You don't need to reinstall Anaconda through the Visual Studio Installer. You can also install a newer version of an interpreter if it isn't yet listed in the Visual Studio Installer.
•Visual Studio supports Python version 3.7. While it's possible to use an earlier version of Visual Studio to edit code written in earlier versions of Python, those versions of Python aren't officially supported. Visual Studio features such as IntelliSense and debugging might not work with earlier versions of Python.
•For Visual Studio 2015 and earlier, use Python 3.5 or earlier. You must manually install one of the Python interpreters.
Visual Studio shows all known environments in the Python Environments window. It automatically detects updates to existing interpreters.
If Visual Studio doesn't detect an installed environment, see Manually identify an existing environment.
If you move an existing interpreter to a new location by using the file system, Visual Studio doesn't automatically detect the change.
•If you originally specified the location of the interpreter through the Python Environments window, you can edit its environment by using the Configure tab in that window to identify the new location. For more information, see Manually identify an existing environment.
•If you installed the interpreter by using an installer program, use the following steps to reinstall the interpreter in the new location:
1.Restore the Python interpreter to its original location.
2.Uninstall the interpreter by using its installer, which clears the registry entries.
3.Reinstall the interpreter at the new location.
3 days ago · Just like CPython, you need a base interpreter environment and then can install extra packages. The choices for installing the base interpreter are: Use conda (x86_64 windows, macOS, linux, arm64 linux) Use your distribution package manager (linux) Use homebrew (macOS) Use the prebuilt tarballs; Build from source
Jul 7, 2002 · CPython’s Windows support currently follows Microsoft’s lifecycles. A new feature release X.Y.0 will support all Windows versions whose extended support phase has not yet expired. Subsequent bug fix releases will support the same Windows versions as the original feature release, even if no longer supported by Microsoft.
