!ls in Jupyter notebook (Python 3)

Question

If I use:

!ls '/Users/martyn/Documents/rawData'

it gives me a list of the files in the required directory.

But I want to paramterize this. I tried:

pathData = '/Users/martyn/Documents/rawData'
!ls pathData

But this gives the error:

ls: pathData: No such file or directory

I can see the problem ... but can't see how to fix it. Any help would be greatly appreciated.

Solution 1

You probably need

!ls {pathData}

or

!ls $pathData

Solution 2

Using only %ls gives you the list in your current directory.
