<p>This component allows you to execute Python code with imported packages.</p>
<p>The <strong>Python Interpreter</strong> component can only import packages that are already installed in your Langflow environment.
If you encounter an <code>ImportError</code> when trying to use a package, you need to install it first.</p>
<p>To install custom packages, see <a class="" href="/install-custom-dependencies">Install custom dependencies</a>.</p>

<ol>
<li class="">To use this component in a flow, in the <strong>Global Imports</strong> field, add the packages you want to import as a comma-separated list, such as <code>math,pandas</code>.
At least one import is required.</li>
<li class="">In the <strong>Python Code</strong> field, enter the Python code you want to execute. Use <code>print()</code> to see the output.</li>
<li class="">Optional: Enable <strong>Tool Mode</strong>, and then connect the <strong>Python Interpreter</strong> component to an <strong>Agent</strong> component as a tool.
For example, connect a <strong>Python Interpreter</strong> component and a <a class="" href="/calculator"><strong>Calculator</strong> component</a> as tools for an <strong>Agent</strong> component, and then test how it chooses different tools to solve math problems.
<img decoding="async" loading="lazy" alt="Python Interpreter and Calculator components connected to an Agent component" src="/assets/images/component-python-interpreter-1ef9e7dec643a216fd5e83c2139d09c9.png" width="3988" height="2928" class="img_ev3q"></li>
<li class="">Ask the agent an easier math question.
The <strong>Calculator</strong> tool can add, subtract, multiple, divide, or perform exponentiation.
The agent executes the <code>evaluate_expression</code> tool to correctly answer the question.</li>
</ol>

<p>If you don&#x27;t include the package imports in the chat, the agent can still create the table using <code>pd.DataFrame</code>, because the <code>pandas</code> package is imported globally by the <strong>Python Interpreter</strong> component in the <strong>Global Imports</strong> field.</p>
<h2 class="anchor anchorTargetStickyNavbar_Vzrq" id="pass-inputs-to-the-python-interpreter">Pass inputs to the Python Interpreter<a href="#pass-inputs-to-the-python-interpreter" class="hash-link" aria-label="Direct link to Pass inputs to the Python Interpreter" title="Direct link to Pass inputs to the Python Interpreter" translate="no">​</a></h2>
<p>To pass inputs to the <strong>Python Interpreter</strong> component, you need to customize the component&#x27;s code to add input fields.
After the input field is added to the component code, the port becomes available for connections.
For example, to connect a <a class="" href="/text-input-and-output"><strong>Text</strong> component</a> and pass a URL value to the <strong>Python Interpreter</strong> component, do the following:</p>
<ol>
<li class="">
<p>Add a <strong>Python Interpreter</strong> component to your flow.</p>
</li>
<li class="">
<p>To modify the <strong>Python Interpreter</strong> component&#x27;s code, click <svg xmlns="http://www.w3.org/2000/svg" width="16" height="16" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="lucide lucide-code lf-inline-icon" aria-hidden="true" focusable="false" role="presentation"><polyline points="16 18 22 12 16 6"></polyline><polyline points="8 6 2 12 8 18"></polyline></svg> <strong>Edit Code</strong>.</p>
</li>
<li class="">
<p>To pass a URL input to the <strong>Python Interpreter</strong> component, make the following changes to the code:</p>
<p>a. Add the URL input field to the <code>inputs</code> list. This creates the input port that other components can connect to.</p>
<p>b. Update the <code>get_globals</code> method to extract the URL value and add it to the globals dictionary.
This makes the <code>url</code> variable available in the component&#x27;s Python code.</p>
<p>c. Update the default Python code value to use the <code>url</code> variable.</p>
<p>The following example demonstrates these modifications.</p>
