Using os.path.isdir Method

You can use os.path.isdir() to check if a directory exists, it really simple. For example,

#!/usr/bin/python3

# Import module
import os

d = "./folder"
print(os.path.isdir(d))

True

The os.path.exists() method returns True if path refers to an existing path or an open file descriptor.

For both files and directories:

#!/usr/bin/python3

# Import module
import os

f = "./folder/file.txt"
print(os.path.exists(f))

d = "./folder"
print(os.path.exists(d))

True
True

You can use pathlib:

#!/usr/bin/python3

# Import module
import pathlib

d = "./folder"
print(pathlib.Path(d).is_dir())

True
