Is this correct

dir = "E:\\Books"
p = Path(dir)

reference : https://pbpython.com/pages/mailinglist.html

os.walk(p)

giving below error:

File "F:\Users\hyg\AppData\Local\Programs\Python\Python35\lib\os.py", line 368, in walk
scandir_it = scandir(top)
TypeError: scandir: illegal type for path parameter

However

os.walk(dir)

works fine

p looks like a pathlib Path, not an os path.
Hard to be sure without full code.

dir = "E:\\Books"
p = Path(dir)

if that is the case, then you can still use os, but you must resolve p first:

os.walk(p.resolve())

better to use a pathlib walk instead (Google: 'pathlib equivalent of os.walk')

Yes, i have imported pathlib
complete code:

from pathlib import Path 
import os

dir_to_scan = "E:\\Books"
p = Path(dir_to_scan)
q = p / 'jpg'
print(q)

for dirName, subdirList, fileList in os.walk(p):
    print('Found directory: %s' % dirName)
    for fname in fileList: 
        print('\t%s' % fname)

It does not say what you are importing, but these should both work:

from pathlib import Path
import os

dir = "D:\\Temp2"
path = Path(dir)

for item in os.walk(path):
    print('path',item)

for item in os.walk(dir):
    print('dir',item)

You get this error because you use Python 3.5.
Have to use Python 3.6 or newer for os.walk() to take pathlib object.
You use can it directly like this os.walk(dir_to_scan).
You should of course install a new version Python 3.8 (3.6-3.7) and pip installation under Windows

Then you can also drop the old string formatting %s' % dirName and use f-string.

from pathlib import Path
import os

dir_to_scan = r"C:\code\img"
p = Path(dir_to_scan)
for root, dirs, files in os.walk(p):
    for fname in files:
        if fname.endswith(('.jpg', '.png')):
            print(f'Image found --> {fname}')

Output:
Image found --> nrk.png
Image found --> test.jpg
