# Code Actions

> Run Python, Bash, PowerShell, and Node.js scripts as code actions within your Blink workflows.

The Blink platform enables running Python, Bash, PowerShell and Node.js scripts using the following actions:

<CardGroup>
  <Card title="Run Bash Script" icon="terminal" href="#run-bash-script" horizontal iconType="solid" />

  <Card title="Run Node.js Script" icon="node-js" href="#run-node.js-script" horizontal iconType="solid" />

  <Card title="Run Python" icon="python" href="#run-python" horizontal iconType="solid" />

  <Card title="Run PowerShell Command" icon="microsoft" href="/docs/integrations/powershell/actions/run-powershell-command" horizontal iconType="solid" />
</CardGroup>

> These Actions are preserved between the different steps of the Workflow execution.
> For example: if you create a file using Python, you can use it in a later Step using any programming language or CLI.

## Run Bash Script

Execute a provided bash script.

<Note>If an error occurs in a command mid-script but the final command succeeds, the action will report success, potentially masking failed commands.</Note>

1. Start by setting up a `Working Directory` using the [Create Working Directory](/docs/workflows/building-workflows/actions/utility-actions/file_system-utilities#create-working-directory) action.
2. Next, write your `bash` script in the code block provided within the 'Run Bash Script' action.
3. Finally, in the `Working Directory` parameter of the 'Run Bash Script' action, enter the name of the `Working Directory` you created in step one.

<Note>
  **Note**

  If there's an error in a command in the middle of the script and the last command succeeds, the entire action will succeed, not revealing that some command may have failed.

1. Start by setting up a `Working Directory` using the [Create Working Directory](/docs/workflows/building-workflows/actions/utility-actions/file_system-utilities#create-working-directory) action.
2. Next, write your `Python` script in the code block provided within the 'Run Python' action.
3. Finally, in the `Working Directory` parameter of the 'Run Python' action, enter the name of the `Working Directory` you created in step one.

### Referencing inputs and step outputs in Python Actions

* **Option 1 - Variable picker:** Use the [variable picker](/docs/workflows/building-workflows/dynamic-variables/variable-picker#using-the-variable-picker) to select the wanted information.

* **Option 2 – Use the “context” object:** In Python steps, you can reference workflow variables using the automatically generated [context object](/docs/workflows/building-workflows/dynamic-variables/expression-language/workflow-engine-variables#python-actions) syntax. The `context object` syntax allows you to access values from previous steps, input parameters, or other variables, and to set new variables within your Python Action.

## Installing pip Package

This is the <span className="badge badge--info">Pip Install</span> action, which allows you to install Python packages and use them with the [Run Python](/docs/workflows/building-workflows/actions/basic-actions/code-actions#run-python) action.

1. To use this action, create a `Working Directory` using the [Create Working Directory](/docs/workflows/building-workflows/actions/utility-actions/file_system-utilities#create-working-directory) action.

2. Specify which python packages you wish to install, by writing a new line separated list of packages, and run the step.

   * For git based packages use the following package name structure:

     `git+<protocol>://<git-provider>/<git-user>/<git-repo>.git`

     **For Example:**

     ```jsx theme={"dark"}

     git+https://github.com/psf/requests.git

     git+ssh://git@github.com/psf/requests.git

     ```
   * To use the `Require Hashes` parameter use the following package name structure:

     `<package>==<version> \`
     `--hash=sha256:<hash1> \`

     **For Example:**

     ```jsx theme={"dark"}
         requests==2.28.2 \
             --hash=sha256:<hash1> \
             --hash=sha256:<hash2>
         certifi==2022.12.7 \
             --hash=sha256:<hash1>
     ```

3. In the `Working Directory` parameter of the [Run Python](/docs/workflows/building-workflows/actions/basic-actions/code-actions#run-python) action, enter the name of the `Working Directory` you created in step one.

4. Finally, if you want to enforce hash verification select `Require Hashes`.

<Note>
  Use a connection when installing from a private repository, there is no need for a connection when installing from public repositories.
