Can't get full output from tree.py, it only returns 'zero' for the target of Start.

Terminal (Mac) output: Wills-Air:python willanderson$ python3 tree.py Projects contains 0 files with a combined size of 0 bytes Wills-Air:python willanderson$

Code: import os

def treewalker(start): total_size = 0 total_files = 0

for root, dirs, files in os.walk(start):
    subtotal = sum(
        os.path.getsize(os.path.join(root, name)) for name in files
    )
    total_size += subtotal
    file_count = len(files)
    total_files += file_count
    print(root, "consumes", end=" ")
    print(subtotal, end=" ")
    print("bytes in", file_count, "non-directory files")

print(start, "contains", total_files, "files with a combined size of", total_size, "bytes")

treewalker ('Projects')

I don't get it, why doesn't it work like the on-screen code (I think it's an exact copy)??

You're running the in the directory you want to evaluate.

Change this line:

treewalker('Projects')

to: 

treewalker('../Projects')

Let me know if that fixes your problem.
