Auto import
When you reference a class that has not been imported, PyCharm helps you locate this file and add it to the list of imports. You can import a single class or an entire package, depending on your settings.
The import statement is added to the imports section, but the caret does not move from the current position, and your current editing session does not suspend. This feature is known as the Import Assistant. Using Import Assistant is the preferred way to handle imports in PyCharm because import optimizations are not supported via command line.
The same possibility applies to XML files. When you type a tag with an unbound namespace, the import assistant suggests creating a namespace and offers a list of appropriate choices.
You can configure the IDE to automatically add import statements if there are no options to choose from.
Press CtrlAlt0S to open settings and then select Editor | General | Auto Import.
In the Python section, configure automatic imports:
Select Show import popup to automatically display an import popup when tying the name of a class that lacks an import statement.
Select one of the Preferred import style options to define the way an import statement to be generated.
When tooltips are disabled, unresolved references are underlined and marked with the red bulb icon . To view the list of suggestions, click this icon (or press AltEnter) and select Import class.
Hover over the inspection widget in the top-right corner of the editor, click , and disable the Show Auto-Import Tooltip option.
If you want to completely disable auto-import, make sure that:
The automatic insertion of import statements is disabled.
The Optimize Imports feature helps you remove unused imports and organize import statements in the current file or in all files in a directory at once according to the rules specified in Settings | Editor | Code Style | <language> | Imports.
tip
You can exclude specific files and folders from import optimization. For more information, refer to Exclude files from reformatting.
Select a file or a directory in the Project tool window (View | Tool Windows | Project).
Do any of the following:
In the main menu, go to Code | Optimize Imports (or press CtrlAlt0O).
From the context menu, select Optimize Imports.
(If you've selected a directory) Choose whether you want to optimize imports in all files in the directory, or only in locally modified files (if your project is under version control), and click Run.
Place the caret at the import statement and press AltEnter or use the icon.
Select Optimize imports.
tip
To optimize imports in a file, you can also press CtrlAltShift0L, select Optimize imports, and click Run.
If your project is under version control, you can configure PyCharm to optimize imports in modified files before committing them to VCS.
note
Press Alt00 to open the Commit tool window and click Show Commit Options .
Click and in the commit message area, select the Optimize imports checkbox.
You can configure the IDE to optimize imports in modified files automatically when your changes are saved.
Press CtrlAlt0S to open settings and then select Tools | Actions on Save.
Enable the Optimize imports option.
Additionally, from the All file types list, select the types of files in which you want to optimize imports.
Apply the changes and close the dialog.
You can tell PyCharm to optimize imports in a file every time it is reformatted.
Open the file in the editor, press CtrlAltShift0L, and make sure the Optimize imports checkbox is selected in the Reformat File dialog that opens.
After that every time you press CtrlAlt0L in this project, PyCharm will optimize its imports automatically.
Start typing a name in the editor. If the name references a class that has not been imported, the following prompt appears:
The unresolved references will be underlined, and you will have to invoke intention action Add import explicitly.
Press AltEnter. If there are multiple choices, select the desired import from the list.
You can define your preferred import style for Python code by using the following options available on the Auto Import page of the project settings (Settings | Editor | General | Auto Import):
from <module> import <name> | import <module>.<name> |
---|---|
tip
PyCharm provides a quick-fix that automatically installs the package you’re trying to import: if, after the keyword
import
, you type a name of a package that is not currently available on your machine, a quick-fix suggests to either ignore the unresolved reference, or download and install the missing package:
PyCharm helps you organize relative and absolute imports within a source root. With the specific intention, you can convert absolute imports into relative and relative imports into absolute.
If your code contains any relative import statement, PyCharm will add relative imports when fixing the missing imports.
Note that relative imports work only within the current source root: you cannot relatively import a package from another source root.
The intentions prompting you to convert imports are enabled by default. To disable them, open project Settings (CtrlAlt0S), select Editor | Intentions, and deselect the Convert absolute import to relative and Convert relative import to absolute.
When you complete a ES6 symbol or a CommonJS module, PyCharm either decides on the style of the import statement itself or displays a popup where you can choose the style you need. Learn more from Auto-import in JavaScript.
PyCharm automatically adds an import statement when you refer any module member or package in the Python code and invoke code completion. Auto-import on code completion is also applied to some popular package name aliases, such as np
for numpy
or pd
for pandas
.
PyCharm also adds import statements when you complete exported JavaScript or TypeScript symbols.
You can disable auto-import on completion and use quick-fixes instead:
In the Settings dialog (CtrlAlt0S) , go to Editor | General | Auto Import.
On the Auto Import page that opens, use the checkboxes in the TypeScript/JavaScript area to enable or disable import generation on code completion.
If you use a module in your code that doesn't have any corresponding stub, PyCharm might show a missing statement error. To suppress this error message, use the # type: ignore
