Explain os. mkdir and os. mkdirs in detail

Create a directory

In Python, you can use the os.mkdir () function to create a directory (creating a level 1 directory).

The prototype is as follows:

os.mkdir(path)

The parameter path is the path to the directory to create.

For example, the directory where hello is to be created under the D disk

>>> import os

>>> os.mkdir('d:\hello')

You can use the os. makedirs () function to create multilevel directories.

The prototype is as follows:

os.makedirs(path)

The parameter path is the path to the directory to create.

For example, create books directory under D disk and books directory under book directory

>>> import os

>>>os.makedirs('d:\\books\\book')

Delete the directory

In Python, you can delete directories using the os.rmdir () function.

The prototype is as follows:

os.rmdir(path)

The parameter path is the path to the directory to be deleted.

For example, D disk hmm directory deleted

>>> import os

>>> os.rmdir('d:\hmm') 

Delete multilevel directories

In Python, you can use the os.removedirs () function to remove multilevel directories.

The prototype is as follows:

os.removdirs(path)

The parameter path is the path to the multilevel directory to be deleted.

>>> import os

>>> os.removedirs('d:\\books\\book')

Note: the directory to be deleted must be an empty directory,

Delete the file

In Python, you can use the os.remove () function to delete a file (note that 1 must be 1 file).

The prototype is as follows:

os.remov(path)

The parameter path is the path to the file to be deleted.

For example, delete book. txt file in books directory under D disk

>>> import os

>>>os.remove('d:\\books\\book\\book.txt')

Directory traversal

In Python, you can use the os.walk () function to traverse the directory.

The prototype is as follows:

>>> import os

>>> os.mkdir('d:\hello')

0

Its parameter path is the directory to be traversed, traverses path, returns 1 object, each part of which is a 3 tuple (' directory x', [directory list under x], and files under x).

Such as:

>>> import os

>>> os.mkdir('d:\hello')

1

Determine if it is a directory

In Python, you can use the os.path.isdir () function to determine if a 1 path is a directory.

Its function prototype is as follows:

>>> import os

>>> os.mkdir('d:\hello')

2

Its parameter path is the path to be judged. Returns TRUE if yes, FALSE if no.

Determine if it is a file

In Python, you can use the os.path.isfile () function to determine whether a 1 path is a file. The function prototype is shown below.

os.path.isfile(path)

Its parameter path is the path to be judged. Returns TRUE if yes, FALSE if no.
