Python Tutorial: OS Module – Use Underlying Operating System Functionality

FavoriteLoadingAdd to favorites

In this Python Tutorial, we will be going over the ‘os’ module. The os module allows us to access functionality of the underlying operating system. So we can perform tasks such as: navigate the file system, obtain file information, rename files, search directory trees, fetch environment variables, and many other operations. We will cover a lot of what the os module has to offer in this tutorial, so let’s get started.

    does this OS module function similar with system calls in C library? Do the instruction of this python library has a higher privilege than normal user mode instructions?

    os.path.join accepts any number of arguments so you can join multiple paths:

    os.path.join(homedir, ‘subdir’, ‘test.txt’)

    How can I open a file like a document, excel or powerpoint to edit it?
    for example: I need to open a CSV file in case the user wants to edit it before use.

    This is sort of a related topic with importing (my personal library is called "common" or more specifically "common.py". On my particular computer I had to include the sys.path.insert(0, ‘j:\blender library\scripts\common\’) so that my other *.py scripts would recognise common.py.

    The real line of interest is reloading a module needs to be reloaded to obtain the lastest changes (without having to restart python).

    #import bmesh
    #import bpy
    import os
    import sys
    import importlib

    # clear the system.console
    os.system("cls")

    # make the default directory where my current script is running….
    os.chdir("j:\blender library\scripts\")

    # add the common directory so my modules can be found when called
    import sys
    sys.path.insert(0, ‘j:\blender library\scripts\common\’)

    # line(s) of interest – import my common module that I reuse over and over again
    import common
    # reload itself … so any recent changes will be included (without having to restart python).
    common = importlib.reload(common)

    Hello,
    I am trying the below :
    print(os.path.splitext(‘G:Titanic Machine learningpoka.txt’))
    The output is :
    (‘G:\Titanic Machine learning\poka’, ‘.txt’)

    I am not sure why the ‘\’ is coming. I am expecting a single ”.
    Any help would be much appreciated.
