To view Python options, use the Tools > Options menu command, make sure Show all settings is selected, and then navigate to Python Tools:
There are also additional Python-specific options on the Text Editor > Python > Advanced tab.
The specific options are described in the following sections:
| Option | Default | Description |
|---|---|---|
| Show the Output Window when creating virtual environments | On | Clear to prevent the output window from appearing. |
| Show the Output Window when installing or removing packages | On | Clear to prevent the output window from appearing. |
| Always run pip as administrator | Off | Always elevates pip install operations for all environments. When installing packages, Visual Studio prompts for administrator privileges if the environment is located in a protected area of the file system such as c:\Program Files. In that prompt you can choose to always elevate pip install for just that one environment. See Python environments - pip tab. |
| Automatically generate completion DB on first use | On | For IntelliSense completions to work for a library, Visual Studio must generate a completion database for that library. Building the database is done in the background when a library is installed, but may not be complete when you start writing code. With this option selected, Visual Studio prioritizes completion of the database for a library when you write code that uses it. |
| Ignore system-wide PYTHONPATH variables | On | PYTHONPATH is ignored by default because Visual Studio provides a more direct means to specify search paths in environments and projects. See Python Environments - search paths for details. |
| Update search paths when adding linked files | On | When set, adding a linked file to a project updates search paths so that IntelliSense can include the contents of the linked file's folder in its completion database. Clear this option to exclude such content from the completion database. |
| Warn when imported module cannot be found | On | Clear this option to suppress warnings when you know an imported module isn't presently available but doesn't otherwise affect code operation. |
| Report inconsistent indentation as | Warnings | Because the Python interpreter depends heavily on proper indentation to determine scope, Visual Studio by default issues warnings when it detects inconsistent indentations that might indicate coding errors. Set to Errors to be even more strict, which causes the program to exit in such cases. To disable this behavior altogether, select Don't. |
| Check for survey/news | Once a week | Sets the frequency at which you allow Visual Studio can open a window containing a web page with Python-related surveys and news items, if available. Options are Never, Once a day, Once a week, and Once a month. |
| Reset all permanently hidden dialogs (button) | n/a | Different dialog boxes provide options such as Don't show me this again. Use this button to clear those options and cause the dialogs to reappear. |
| Option | Default | Description |
|---|---|---|
| Prompt before running when errors are present | On | When set, prompts you to confirm that you want to run code that contains errors. Clear this option to disable the warning. |
| Wait for input when process exits abnormally Wait for input when process exits normally |
On (for both) | A Python program started from Visual Studio runs in its own console window. By default, the window waits for you to press a key before closing it regardless of how the program exits. To remove that prompt and close the window automatically, clear either or both of these options. |
| Tee program output to Debug Output window | On | Displays program output in both a separate console window and the Visual Studio Output window. Clear this option to show output only in the separate console window. |
| Break on SystemExit exception with exit code of zero | Off | If set, stops the debugger on this exception. When clear, the debugger exits without breaking. |
| Enable debugging of the Python standard library | Off | Makes it possible to step into the standard library source code while debugging, but increases the time it takes for the debugger to start. |
| Option | Default | Description |
|---|---|---|
| Scripts | n/a | Specifies a general folder for startup scripts to apply to interactive windows for all environments. See Startup scripts. Note, however, that this feature does not currently work. |
| Up/down arrows navigate history | On | Uses the arrow keys to navigate through history in the interactive window. Clear this setting to use the arrow keys to navigate within the interactive window's output instead. |
| Completion mode | Only evaluate expressions without function calls | The process of determining the available members on an expression in the interactive window may require evaluating the current unfinished expression, which can result in side-effects or functions being called multiple times. The default setting, Only evaluate expressions without function calls excludes expressions that appear to call a function, but evaluates other expressions. For example, it evaluates a.b but not a().b. Never evaluate expressions prevents all side-effects, using only the normal IntelliSense engine for suggestions. Evaluate all expressions evaluates the complete expression to obtain suggestions, regardless of side effects. |
| Hide static analysis suggestions | Off | When set, displays only suggestions that are obtained by evaluating the expression. If combined with the Completion mode Never evaluate expressions, no useful completions appear in the interactive window. |
| Option | Default | Description |
|---|---|---|
| Member completion displays intersection of members | Off | When set, shows only completions that are supported by all possible types. |
| Filter list based on search string | On | Applies filtering of completion suggestions as you type (default is checked). |
| Automatically show completions for all identifiers | On | Clear this option to disable completions in both the editor and interactive windows. |
| Option | Default | Description |
|---|---|---|
| Enter outlining mode when files open | On | Automatically turn on Visual Studio's outlining feature in the editor when opening a Python code file. |
| Paste removed REPL prompts | On | Removes >>> and ... from pasted text, allowing easy transfer of code from the interactive window to the editor. Clear this option if you need to retain those characters when pasting from other sources. |
| Color names based on types | On | Enables syntax coloring in Python code. |
