| Python Interpreter | Select one of the pre-configured [Python interpreters](configuring-available-python-interpreters.html).  |
| Interpreter options | In this field, specify the [command-line options](https://docs.python.org/3/using/cmdline.html#command-line) to be passed to the interpreter. If necessary, click ![Expand the field](https://resources.jetbrains.com.cn/help/img/idea/2026.2/app.general.expandComponent.svg), and type the string in the editor.  |
| Working directory |    Specify a directory to be used by the running task.                         * When a default run/debug configuration is created by the keyboard shortcut `Ctrl+Shift+F10` (Windows), `⌃ ⇧ R` (macOS), `⌃ ⇧ F10` (IntelliJ IDEA Classic (macOS)), `⌃ ⇧ R` (macOS System Shortcuts), `Ctrl+Shift+F10` (XWin), `Ctrl+Shift+F10` (GNOME), `Ctrl+Shift+F10` (KDE), `Ctrl+Shift+F10` (Emacs), `Ctrl+Shift+F10` (Sublime Text), `Ctrl+Shift+F10` (Sublime Text (macOS)), `⌘ ⌥ U` (Xcode), `Ctrl+Alt+F5` (Visual Studio), `⌃ ⌥ F5` (Visual Studio (macOS)), `Ctrl+Alt+F5` (ReSharper), `⌃ ⌥ F5` (ReSharper (macOS)), `Ctrl+Shift+F10` (QtCreator), `⌃ ⇧ R` (QtCreator (macOS)), `Alt+Shift+F6` (NetBeans), `Ctrl+Shift+F10` (Eclipse), `⌃ ⇧ R` (Eclipse (macOS)), or by choosing `Run` from the context menu of a script, the working directory is the one that contains the executable script. This directory may differ from the project directory.    * When this field is left blank, the `bin` directory of the CLion installation will be used.      You can use [path variables](absolute-path-variables.html) in this field.     |
|  Add content roots to PYTHONPATH  | Select this checkbox to add all [content roots](null) of your project to the environment variable PYTHONPATH.  |
| Add source roots to PYTHONPATH |  Select this checkbox to add all [source roots](null) of your project to the environment variable PYTHONPATH.  |
| Docker container settings     > **Warning:** > This field only appears when a [Docker-based remote interpreter](docker.html) is selected for a project..     > **Note:** > Speaking about the correspondence of settings with some options (`--net`, `--link`, and so on), note that these options come from [Docker command line arguments](https://docs.docker.com/engine/reference/commandline/run/).       Click ![the Browse button](https://resources.jetbrains.com.cn/help/img/idea/2026.2/app.general.ellipsis.svg) to open the dialog and specify the following settings:                      |
| Options |      * Disable networking: select this checkbox to have the networking disabled. This corresponds to `--net="none"`, which means that inside a container the external network resources are not available.    * Network mode: corresponds to the other values of the option `--net`. * `bridge` is the default value. An IP address will be allocated for container on the bridge’s network and traffic will be routed through this bridge to the container. Containers can communicate via their IP addresses by default. To communicate by name, they must be linked. * `host`: use the host's network stack inside the container. * `container:<name\|id>`: use the network stack of another container, specified via its name or id. For more information, refer to the [Network settings](https://docs.docker.com/engine/reference/run/#network-settings) documentation.    * Links: Use this section to link the container to be created with the other containers. This is applicable to `Network mode = bridge` and corresponds to the `--link` option.    * Publish all ports: Expose all container ports to the host. This corresponds to the option `--publish-all`.    * Port bindings: Specify the list of [port bindings](https://docs.docker.com/engine/reference/run/#expose-incoming-ports). Similar to using the `-p` option with `docker run`.    * Extra hosts: This corresponds to the `--add-host` option. For more information, refer to [Managing /etc/hosts](https://docs.docker.com/engine/reference/run/#managing-etc-hosts).    * Volume bindings: Use this field to specify the bindings between the special folders-volumes and the folders of the computer, where the Docker daemon runs. This corresponds to the `-v` option. For more information, refer to [Managing data in containers](https://docs.docker.com/userguide/dockervolumes/).    * Environment variables: Use this field to specify the list of environment variables and their values. This corresponds to the `-e` option. For more information, refer to [ENV (environment variables)](https://docs.docker.com/engine/reference/run/#env-environment-variables).     Click ![](https://resources.jetbrains.com.cn/help/img/idea/2026.2/app.expui.general.moveDown.svg) to expand the tables. Click ![](https://resources.jetbrains.com.cn/help/img/idea/2026.2/app.expui.general.add.svg), ![](https://resources.jetbrains.com.cn/help/img/idea/2026.2/app.expui.general.remove.svg), or ![](https://resources.jetbrains.com.cn/help/img/idea/2026.2/app.expui.general.edit.svg) to make up the lists.    |

## Logs

The following options are related to logging the execution of this configuration. For more information, refer to [](null).

| Item | Description |
| --- | --- |
| Specify logs to be shown in the console   |    Specify which log files to display while running the application.                               Click ![the Add button](https://resources.jetbrains.com.cn/help/img/idea/2026.2/app.expui.general.add.svg) to add a new log. In the Edit Log Files Aliases dialog, configure the following:                                 * Alias: The name of the tab where the log will be displayed.    * Log File Location: Specify the path to the log file or an [Ant pattern](https://ant.apache.org/manual/dirtasks.html). If several files of a rolling log match the pattern, CLion will display the most recent one.    * Show all files coverable by pattern: Show all logs that match the pattern.                              For logs in the table, you can configure the following options:                                * Is Active: Display the specified log file.    * Skip Content: Do not display old log messages from previous runs.    |
