FileNotFoundError even though Absolute Path Specified

Question

I am running a simple python webserver [SimpleHTTPServer] in my Linux . Wrote a python program to download all the files hosted in that server to my Windows Machine . But for some reason program is throwing FileNotFoundError even though Directory exists and I've provided Absolute Path .

Here is the code : https://drive.google.com/file/d/1CDrueDJcbu2z1XeeB_iYv0zmfIX1cCkx/view?usp=sharing

It's working correctly in Linux but trouble with Windows . Thanks
