**Python file**  
_test.py_

````
```
sysman_auth = (username, password)
```

````

**Robot file**  
_sample.robot_

````
```
***Variables***
${uname} testuser
${password} testpassword
```

````

How do I pass _testuser_ and _testpassword_ from sample.robot file to test.py file?

Hi,  
If by ‘passing it to .py’ you mean using one of the functions in the .py file as a keyword, there are 2 ways to do that which I elaborated on this article - [Extend robotframework using the robotframework python lib core | by Eldad Uzman | Medium](https://eldadu1985.medium.com/extend-robotframework-using-the-robotframework-python-lib-core-bf73e09160d3)

If instead you mean running the .py file as a script with arguments then you need to execute it in a different process and you can do that with robot frameworks operating system library - [OperatingSystem - Documentation](https://robotframework.org/robotframework/2.1.2/libraries/OperatingSystem.html)
