What is different between makedirs and mkdir of os?

Question

I am confused to use about these two osmethods to create the new directory.

Please give me some example in Python.

Answer 1

(Can not comment, just add to NPE's answer.)

In Python3, os.makedirs has a default parameter exist_ok=False.
If you set it to True, then os.makedirs will not throw any exception if the leaf exists.
(While os.mkdir doesn't have this parameter.)

Just like this:

os.makedirs('dirA', exist_ok=True)

P.S.
You can type ? before the name of a method in IPython shell to take a quick look at the documentation.
e.g.:

>>> import os
>>> ? os.makedirs
