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.
#### 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.
You can also write custom Python code to get the data from **External APIs** and manipulate the response for graphical representation.
