I would like to give a directory and then report on the extensions

Resolved Question:

I would like to give a directory and then report on the extensions within the directory.
List each type of extension, count of extension, and total file size of extensions.

Output can be simple (extension, count, total size) like this:

.xlsx 2 1000
.py 1 590


This is what I have written so far. It kind of works. The output I am getting is writing the total of all files for each type of extension.

import os, os.path, collections
extensionCount = collections.defaultdict(int)
os.chdir('Test') #change to a directory in CWD

for root, dirs, files in os.walk('.'):
for file in files:
base, ext = os.path.splitext(file)
extensionCount[ext.lower()] += 1
size = os.path.getsize(file)

for ext, count in sorted(extensionCount.items(), key=lambda x: x[1], reverse=True):
print(ext, count, size)

('.docx', 2, 592L)
('.py', 1, 592L)

#I have a directory called "test" with three files equalling 592 bytes, which is the total
#of the three files.

Hi Lindie,


 


No answer yet. Thanks for checking in with me.

Customer: replied 1 year ago.

I just tried this as well. I almost have what I want. I am just missing how to combine the extensions and their file size.


 


I am getting results like this:


Extension .ico | Filesize 19790 bytes
Extension .ico | Filesize 19790 bytes
Extension .pyd | Filesize 132096 bytes
Extension .dll | Filesize 73216 bytes
Extension .pyd | Filesize 9728 bytes


 


I would like this to be more of a summary where the extension are listed only once with the file sizes summed. My script is below.


 


import os
import glob


os.chdir(r'C:\Python33\DLLs')



for filename in glob.glob ('*'):
filesize = os.path.getsize(filename)
extension = os.path.splitext(filename)[1]
print("Extension",extension,"|","Filesize", filesize,"bytes")

Hello,


 


Thank you for responding. I also need to include a count of the particular extension. This is a pretty long post and perhaps this requirment was lost. It is in the first post of mine. Do you think you would be able to include a count for the extension as shown below - just a number at the end of the row?


 


Extension .dll | Total space used (NNN) NNN-NNNNbytes | 2

No problem but I'm not at a computer at the moment
Can it wait until the morning?
Customer: replied 1 year ago.


Awesome. Thank you. I am not in a super rush and I can wait. No problem. I am new to programming and just can't figure out how to get the the file size, extension list, and count all together.

 

Thanks.

Expert:  Ingo U replied 1 year ago.
OK, here it is:

If you want, I could also give you min/max/average size numbers...
Customer: replied 1 year ago.


I did not think of min/max/average. I you could do that it would be great! That would be all I needed.
