Moving files to different directories based on key in dictionary - file

Question

I am new to this, please tell me if the form is not correct.
I am trying to move my images from a file to a new empty files based on their name related to their key in the dictionary I created. Basically their label.
The dictionary is of this form:
print(multivalue_dict)
defaultdict(list,{'cat_a': ['55b85ea15a1536d46b7190ad6fff8ce7.jpg',
'd4684dcdc759dd9cdf41504698d737d8.jpg',
'6325b6870c54cd47be6ebfbffa620ec7.jpg'],
'cat_b': ['55b85ea15a1536d46b7190ad6fff8ce7.jpg',
'd4684dcdc759dd9cdf41504698d737d8.jpg',
'6325b6870c54cd47be6ebfbffa620ec7.jpg'],....}
The desired outcome would be then to have a file cat_a with all the images inside.
I am trying use the path and shutil
import os
import shutil
source_dir = "/Users/Me/Downloads/File/Images"
for key in multivalue_dict:
target_dir = f"/Users/Me/Downloads/File/{key}"
for file in multivalue_dict[key]:
shutil.move(os.path.join(source_dir, file_name), target_dir)
Though, I get the error:
Error Traceback (most recent call last)
/var/folders/gs/0bx6d0ms3jxfgjd6vfkz22l40000gn/T/ipykernel_29606/1312100907.py in
7 if os.path.exists(file):
8 pass
----> 9 shutil.move(os.path.join(source_dir, file_name), target_dir)
/Users/anaconda3/lib/python3.9/shutil.py in move(src, dst, copy_function)
821
822 if os.path.exists(real_dst):
--> 823 raise Error("Destination path '%s' already exists" % real_dst)
824 try:
825 os.rename(src, real_dst)
Error: Destination path '/Users/Me/Downloads/File/cat_a/f54d0c5cbd8e2270742293edf9075cb1.jpg' already exists
It seems that it is able to transfer 1 image to a new file but then stop, because it loops over it again.

Found the solution using iterrows() and pathlib rather than dictionary and shutil.
from pathlib import Path
for (index,row) in df.iterrows():
for label in label_list:
if row.product_cat == label:
p = Path(f'/Users/Me/Downloads/Images/{row.image}')
p.rename(Path(f'/Users/Me/Downloads/Images/{label}/{row.image}'))
