When importing path from .env file I get two extra brackets added everywhere in the path variable?

Question

PATH_OLD = r'C:\Users\Bilal\Python\Task1\OlderVersionFiles\' in my .env file. I get the following:

"r'C:\\\\Users\\\\Bilal\\\\Python\\\\Task1\\\\OlderVersionFiles\\\\'"

instead of

r'C:\\Users\\Bilal\\Python\\Task1\\OlderVersionFiles\\'

on running the following code:

import os
from dotenv import load_dotenv
load_dotenv()
result = os.getenv("PATH_OLD")
#Prints the correct path here
print(result)
dir_A_dict = dict()
directory_A = result
dir_A_files= [os.path.join(directory_A, x) for x in os.listdir(directory_A) if '.csv' in str(x)]

Gives the following error:

dir_A_files= [os.path.join(directory_A, x) for x in os.listdir(directory_A) if '.csv' in str(x)]
OSError: [WinError 123] The filename, directory name, or volume label syntax is incorrect: "r'C:\\\\Users\\\\Bilal\\\\Python\\\\Task1\\\\OlderVersionFiles\\\\'"
