os in python code example

Example 1: how to make an os in python

nfortunately Python is classified as a very high level programming language. It cannot be used, for example, to directly access hardware and perform low-level data structure manipulation. It is completely dependent on something to abstract the hardware from it, and that is the Kernel. It is, however, technically possible to create an operating system centered on Python, that is; have only the very low level stuff in written in C and assembly and have most of the rest of the operating system written in Python.

Example 2: import os in python meaning

import os

Executing a shell command
os.system()    

Get the users environment 
os.environ()   

#Returns the current working directory.
os.getcwd()   

Return the real group id of the current process.
os.getgid()       

Return the current process’s user id.
os.getuid()    

Returns the real process ID of the current process.
os.getpid()     

Set the current numeric umask and return the previous umask.
os.umask(mask)   

Return information identifying the current operating system.
os.uname()     

Change the root directory of the current process to path.
os.chroot(path)   

Return a list of the entries in the directory given by path.
os.listdir(path) 

Create a directory named path with numeric mode mode.
os.mkdir(path)    

Recursive directory creation function.
os.makedirs(path)  

Remove (delete) the file path.
os.remove(path)    

Remove directories recursively.
os.removedirs(path) 

Rename the file or directory src to dst.
os.rename(src, dst)  

Remove (delete) the directory path.
os.rmdir(path)

Example 3: import os in python meaning

The OS module in Python provides a way of using operating system dependent
functionality. 

The functions that the OS module provides allows you to interface with the
underlying operating system that Python is running on – be that Windows, Mac or
Linux. 

You can find important information about your location or about the process. 

In this post I will show some of these functions.

Example 4: python os module

#the os module provides an operating system interface from Python
import os
#prints the name of the operating system
print(os.name)
#prints the absolute path for the module
print(os.getcwd())

Example 5: import os python

import os
os.listdir("*\")[0]

Example 6: os module in python

# Delete everything reachable from the directory named in "top",
# assuming there are no symbolic links.
# CAUTION:  This is dangerous!  For example, if top == '/', it
# could delete all your disk files.
import os
for root, dirs, files in os.walk(top, topdown=False):
    for name in files:
        os.remove(os.path.join(root, name))
    for name in dirs:
        os.rmdir(os.path.join(root, name))
