#### Problem description

I inputted the following code into JupyterLab and I know the path is right and I've tried switching / for \ using // and adding r in front of the C. I still get the following error. I also tried reloading the pandas library. 


#### Expected Output

to pull up the data on Jupyterlab notebook in a table like format hopefully.
