Python find out if a folder exists

Question

I am trying to find out if a folder exists but for some reason cannot. I am generating a string, and use os.path.isdir to find out if a folder with that string`s name already exists. The thing is - I get 'False' regardless.

import os

my_Folder_Name = 'some_string' #This is a string that I generate
print(os.path.isdir("\\" + my_Folder_Name)) #Even if this folder exists - I get False

What am I doing wrong here?

Use `os.path.join` to join path names in an OS independent way. — Chris Mueller, Mar 24 '17 at 12:33

import os

my_Folder_Name = 'some_string' #This is a string that I generate
print(os.path.isdir(my_Folder_Name))

remove "//". Why are you using "//"?

Either use the relative path or the absolute one. Don't append '\' to your folder path.

print(os.path.isdir(my_folder_name))

(Sorry to digress, but variable names follow snake case convention in python. So if you can change that too, other python programmers would be happier)
