linux - How to check existence of a folder with python and then remove it?
I want to remove dataset folder from dataset3 folder. But the following code is not removing dataset. 
First I want to check if dataset already exist in dataset then remove dataset. 
Can some one please point out my mistake in following code?

Python's os.rmdir() only works on empty the directories, however shutil.rmtree() doesn't care (even if there are subdirectories) which makes it very similar to the Linux rm -rf command.
import os
import shutil

dirpath = os.path.join('dataset3', 'dataset')
if os.path.exists(dirpath) and os.path.isdir(dirpath):
    shutil.rmtree(dirpath)

Modern approach
In Python 3.4+ you can do same thing using the pathlib module to make the code more object-oriented and readable:
from pathlib import Path
import shutil

dirpath = Path('dataset3') / 'dataset'
if dirpath.exists() and dirpath.is_dir():
    shutil.rmtree(dirpath)
