We welcome code contributions - see Contributing for information. Documentation contributions may be made at the visualstudio-docs repository.

Visual Studio 2017 and Visual Studio 2019 installation

The Python development workload is available as part of Visual Studio Community, Professional and Enterprise. To install, run the normal VS installer and select either the Python development workload or the Data science and analytical applications workload.

Visual Studio 2015 and earlier

Prior to Visual Studio 2017, Python support was released as a standalone extension. We are no longer actively developing these versions, but if you are unable to upgrade to Visual Studio 2017 yet, you can use these older installers to get Python support.

PTVS 2.2.6 is the latest available version for Visual Studio 2015. You can also find it in the Visual Studio 2015 installer by selecting "Custom" and looking under the "Programming Languages" category.

PTVS 2.2.2 is the last release for Visual Studio 2013 users.

Thank you for using and supporting Python Tools for Visual Studio.

No Official Python 3.8 Support for Visual Studio 16.4

While we work to fully support code analysis for the recent inclusions to Python 3.8, below are a list of the language-specific features that our parser will not be able to recognize and will surface as ‘red squiggles’ in the IDE:

• Assignment Expressions • Positional-Only Parameters • f-strings debug specifier support

Using any one of these features may trigger a warning message when you launch the project:

To avoid this, disable the warning by navigating to Tools > Options > Python > Debugging and deselecting the option Prompt before running when errors are present.

Moreover, for f-strings support, our current code analysis will not offer completions.

There are also some known issues with using the legacy debugger to attach to a running Python process (see GH5853).

The following capabilities that you know and love will continue to function as normal in Visual Studio for python environments such as:

• Debugging (both Native Debugging and Standard Debugging) • Virtual/Conda Environments • Package Manager • Testing (pytest and unittest, Code Coverage) • Interactive Window • Intellisense in most scenarios

This is by design. VS 2022 uses Pylance as the Intellisense engine which requires node.js.

Jörg Gerigk on 1/13/2022, 00:13 AM:

Apologies, I seem to have not been clear in my description. node.js uses 20% of CPU time after launching this python project, e.g. about 2 cores on my machine. Each time that is and ad infinitum. This is the very definition of a problem as I doubt that an idling Visual Studio is designed to burn through CPU cycles like this.

Could you please look into this? I am happy to provide further information to get this resolved.

Intellisense fails to scrape modules from other projects
Upgraded to VS2017 15.4.2 today, was pleased that error highlighting has been fixed. However, modules still fail to import from other projects.

Steps to reproduce:

Install VS2017 15.4.2 with Python Support

Create new solution with project inside (here, its called PythonApplication1)

Create another project in the solution (here, its called other_module), with other_project.py inside.

Add to PythonApplication1's Search Paths the directory of other_module.

Attempt to import other module.

Observe failure of Intellisense to recognize other_module.

Refreshing DB does nothing. Adding other_module to References does nothing.

Screenshots of various behaviors observed:

Importing modules from other projects was supported at one time, so I assume this is a bug. I still have one computer with VS2017 15.3 on it, everything works great in that version.

Here is the gist of the python tools diagnostic https://gist.github.com/joseortiz3/def9d14386aa82ec176401d88cff1013

Use type hints in Python 3.x to infer variable types if possible

Even though Python ignores type hints at runtime and they can be pretty much any expression, we should use them to infer variable types in a function if we possibly can.

See PEP 484

Debugger silently calls __iter__() and next()
Try to debug this code:

import os class MyIterator(list): def __iter__(self): return self def next(self): os._exit(1) a = MyIterator() print(a) # put a breakpoint here

You will find that the debugger will quit before you even attempt to do anything.

This should not happen. If the debugger insists on iterating through members of every subclass of list silently, then it should really call list.__iter__(instance) rather than iter(instance). Otherwise it breaks debugging on the entire codebase, since the iterator is silently consumed and hence the program no longer behaves correctly when stepping through.

Note that similar problems probably exist for other types, not just list. More generally, I think the debugging experience of subclasses of basic types needs improvement; it is currently not robust.

(This bug probably touches on similar aspects of the debugger as #3505.)

[3dsmax][Maya] Intellisense works for a moment, then all modules become

Hi all:

I'm trying to get 3ds max 2015 working with Intellisense in PTVS. I have VS 2013 installed.

I configured the python interpreter to use the same paths that I do in PyCharm, and set the project search paths the same way, along with also setting the project references to a _MaxPlus.pyd file as well. When I first open my python project using the default Python interpreter and then open my 3ds max project, initially I am able to actually get intellisense working for the MaxPlus module and other built-in modules such as sys, os etc, and able to even get auto-completions working. However, after a few seconds, suddenly all auto-completions will stop, and I will get the No completions dialog, along with everything, even builtins such as sys and os showing unknown type.

Clearly, things are working before something happens in the background that breaks everything related to Intellisense, so could anyone point me as to how I might resolve/narrow down what's causing this issue? I have tried refreshing the db as well, but that has not helped.

How I have my Python Project set up: http://i.imgur.com/hokUFi2.png

How I have the 3ds max python interpreter configured: http://i.imgur.com/HySEXjs.png

I should point out here that I have used the same paths and .pyd file to get 3ds max auto-completion working in both PyCharm and Wing IDE flawlessly; this is my first time trying to use PTVS with 3ds max however, so if anyone spots me doing something incorrect in the setup here, I'd appreciate some pointers.

UPDATE: I attempted the workaround as detailed here: https://pytools.codeplex.com/workitem/3005 by setting HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\12.0\PythonTools\Options\[email protected] to 10000. I also tried installing the latest development release of PTVS. The odd thing is that sometimes I do get intellisense working on certain modules such as MaxPlus, sometimes not. Additionally, I have issues with modules that say they have been indexed in the database such as PySide, but when I do an import statement such as import PySide, they show themselves as unknown type again as well. Builtins such as sys, os, ctypes etc. seem to work now though.

The last thing is that I tried adding one of my current production 3ds max projects to PTVS, but for some reason, even though the PYTHONPATH and search paths are set up exactly the same way as I have them in PyCharm, my modules seem to be incorrectly trying to reference a folder level that they shouldn't be when determining the module root folder, and this is using a virtualenv as well.

A screenshot of that project and its search paths is as shown here: http://i.imgur.com/9QReX5i.png

I'm expecting to be able to do a import stkToolkit_3dsmax and have the module have Intellisense on it, but somehow it seems to be taking scripts (the solution's parent folder) as the top-level module for some reason.

Anyone got any idea on what might be causing this issue, I'd love to have your input (on top of the general slowdown in PTVS, such as almost-hanging when right clicking on items in my solution explorer as well)

Thanks!

Pylance integration

Replace the old out-of-proc custom analyzer with LSP compliant Pylance language server that is now available in preview for VS Code.

Replace the old custom implementation of editor functionality like IntelliSense, Find All References, Goto Definition, Outlining, Refactor Rename, etc with the Visual Studio "Language Client" implementation, which is a reusable adapter that implements those features for LSP compliant language servers.

Python debug: invalid condition in a breakpoint makes VS stuck in the error dialog

This issue has been moved from a ticket on Developer Community.

[severity:It's more difficult to complete my work] If a condition in a breakpoint in Python code cannot be evaluated, there's no way to disable or edit it during a debug run, or otherwise exit the debugger, other than closing an error dialog on every (out of possibly very many) its popup.

Visual studio 2022 can't install extensions (IronPython or AlterNet Studios)

I have the updated community version of Visual studio 2022 It is working perfectly. Except from the extensions. I wanted to make an app using the wpf .net thing on visual studio because its really good for that. And i really wanted to code it in python but then i realized visual studio does not have wpf for python.

So then i tried to download it from other sources. First i downloaded it from the official IronPython Github (the most recent version) And i did the installer and it looked like it should of worked. Iron python is meant to show up in visual studio when you make a new file but it did not. So then i searched IronPython on my computer and i could run it in the command prompt version but not in visual studio.

Next i tried to download alternet studios using the visual studio extensions installer. Which then took me to the website and after i installed it and i could run it in its own app i checked visual studio and it said it was installed but it would not let me make a python wpf .net file like i was meant to be able too. It was like i installed the extension but it did not do anything (it said it was enabled) I looked at loads of youtube videos and searched it up but none of the ideas solved it because they were not the problem.

Thanks for the help.

Changing error messages - differences in reported errors between VS and pyright cli

Describe the bug After starting n (1<= n <= 10) debug sessions, the reported errors change. Usually at this point in time, the Output-Pylance entry in the drop-down menu disappears

Steps to Reproduce Open project - Errors reported:

Start debug sessions. After a couple of runs, error reporting will change: (this has nothing to do with the current problems with flask, another project not using flask exhibits the same behavior) The change in error reporting always happens, surprisingly this time the output-pylance entry did not disappear:

Notable difference is the line saying "no source files found"

Editing code yields new error messages but only on the new baseline. The initially reported errors are still there but do not get reported.

Expected behavior Stable and reliable reporting of errors

Additional context and screenshots I have not been able to force output-pylance to disappear, after some debug sessions it is gone.
