How to display folder contents in jupyter notebook using os

So I want to see the contents of my folder, it is a local folder and is in the same directory.

for i in os.listdir('/salesinfo'):
    print(i)

when I run this code it says it cannot find the directory
But this folder is in the same directory as the file I am writing this in, does this mean I need to change the folder location?

>Solution :

You forgot to add the relative marker ./:

for i in os.listdir('./salesinfo'):
    print(i)
