Which is the best practices to create variables for xpaths?

Example:  
1.$(username\_input) //input[@name=‘username’]  
2.$(UsernameInput) //input[@name=‘username’]  
3.$(USERNAME\_INPUT) //input[@name=‘username’]  
4.$(Username\_Input) //input[@name=‘username’]

Thanks

```python
${USERNAME_INPUT} //input[@name=‘username’]

```

A common practice (and also recommended in the [Robot Framework Style Guide](https://docs.robotframework.org/docs/style_guide#variables-within-settings-section)) is to use ALL CAPS for constants.
