I am attempting to write a code for class and was having trouble with the end and ran across this as a solution: 

 

for file in os.listdir(cats_path):
   print('{0} : {1} bytes'.format(file, os.path.getsize(cats_path / file)))

 

I am trying to list to contents of a folder in bytes.  When attempting this code, I am getting this error: 

 

line 24, in
   print('{0} : {1} bytes'.format(file, os.path.getsize(cats / file)))
TypeError: unsupported operand type(s) for /: 'str' and 'str'

 

Can you tell what I am doing wrong?
