What is different between makedirs and mkdir of os?

by

makedirs() creates all the intermediate directories if they don’t exist (just like mkdir -p in bash).

mkdir() can create a single sub-directory, and will throw an exception if intermediate directories that don’t exist are specified.

Either can be used to create a single ‘leaf’ directory (dirA):

  • os.mkdir('dirA')
  • os.makedirs('dirA')

But makedirs must be used to create ‘branches’:

  • os.makedirs('dirA/dirB') will work [the entire structure is created]

mkdir can work here if dirA already exists, but if it doesn’t an error will be thrown.

Note that unlike mkdir -p in bash, either will fail if the leaf already exists.
