title: Run Python code

You can write custom Python code to interact with components and queries. To do that, you just need to create a new query and select **Run Python Code** from the available datasources.
|
|
|
|
<div style={{textAlign: 'center'}}>
|
|
|
|
<img className="screenshot-full" src="/img/datasource-reference/custom-python/run-py.png" alt="Run JavaScript code" />
|
|
|
|
</div>
|

|
#### Example: Using Python code to trigger component specific actions
|
|
|
|
- Let's drag a **button** and a **text** widget onto the canvas. We will set a text on the text component and trigger button click event from the Python query.
|
|
- Click on the `+` on the query panel to create a query and select **Run Python code** from the available datasources
|
|
- Let's write the code in **Python Editor** and save the query:
|
|
|
|
```python
|
|
class Person:
|
|
def __init__(self, name, age):
|
|
self.name = name
|
|
self.age = age
|
|
|
|
def myfunc(self):
|
|
return "Hello my name is " + self.name
|
|
|
|
p1 = Person(tj_globals.currentUser.firstName, 36)
|
|
|
|
components.text1.setText(p1.myfunc())
|
|
components.button1.click()
|
|
```
|
|
- The code above has a function `myfunc` which returns a string and we using the component specific action to set the **text component**'s value from the Python query. We are also triggering the button click using `components.button1.click()`
|
|
|
|
:::tip
|
|
- ToolJet's global variables can be accessed using **tj_globals**. ex: `tj_globals.currentUser.firstName`
|
|
- As of now, Run Python code only supports the [Python standard library](https://docs.python.org/3/library/) only.
|
|
- Check **[RunPy Limitations](/docs/contributing-guide/troubleshooting/runpy-limitations)**
|
|
:::
|
|
|
|
- Let's edit the properties of widgets:
|
|
- Add an event handler to the button - Select **On Click** event, **Show alert** action, and set a success message `Triggered using RunPy`. This will show a success alert popup whenever the button click event is triggered from the Python code.
|
|
- For the text component, we don't have to edit any property since we are changing the value directly from the Python code.
|
|
|
|
<div style={{textAlign: 'center'}}>
|
|
|
|
<img className="screenshot-full" src="/img/datasource-reference/custom-python/runpyg.gif" alt="Run Python code" />
|
|
|
|
</div>
|
|
|
|
You can also write custom Python code to get the data from **External APIs** and manipulate the response for graphical representation.
