Hello,

kindly, this code doesn’t work could you check:

```auto
vendor = "CiScO"
print(f"Router is from vendor: {vendor.title()}.")

```

Hello @ahmedamrici ,

This is working for me:

```auto
>>> vendor = "CiScO"
>>> print(f"Router is from vendor: {vendor.title()}.")
Router is from vendor: Cisco.

```

On Python 3.8.6. `title` is a string method.

Thanks dear I had below error, I did correct it  
AttributeError: ‘str’ object has no attribute ‘litle’. Did you mean: ‘title’?

but why don’t you show the print output in the lessons ?

We use [trinket](https://trinket.io) for lessons so it’s interactive:

For local testing, it’s best to use vscode.

Hello Ahmedlmad

Using the Trinket applet, you can see the output in the pane on the right in the lessons. For the particular code you mentioned, I get this:

 ![image](https://forum.networklessons.com/uploads/default/original/2X/d/db630971cda20c0a6989cb9e000036cf345ed331.png)  
You can see the output on the right. You can also display the console output by clicking the “Console” option as shown below:

Does that make sense?

I hope this has been helpful!
