You may need to change this command as follows throughout this section. On most Mac OS X systems, replace./python with./python.exe. On Windows, use python.bat. If using Python 2.7, replace test with test.regrtest. If you don’t have easy access to a command line, you can run the test suite from a Python or IDLE shell:. Fortunately, python has the “Python for Windows Extensions” package known as pywin32 that allows us to easily access Window’s Component Object Model (COM) and control Microsoft applications via python. This article will cover some basic use cases for this type of automation and how to get up and running with some useful scripts. Today the Windows team announced the May 2019 Update for Windows 10.In this post we’re going to look at what we, Microsoft’s Python team, have done to make Python easier to install on Windows by helping the community publish to the Microsoft Store and, in collaboration with Windows, adding a default “python.exe” command to help find it. Opening Up Wordpad. The code below shows how to open up Wordpad on a Windows computer. Import subprocess subprocess.Popen ('C:WindowsSystem32write.exe') The code above will open up Wordpad on a Windows computer. And there are many other. Manually Locate Where Python is Installed. Alternatively, you can manually locate where Python is installed by typing ‘Python’ in the Windows Search Bar: Right-click on the Python App, and then select “Open file location” as captured below: Right-click on the Python shortcut, and then select Properties: Click on “Open File Location“.

Welcome to Python Run Shell Command On Windows tutorial. In this tutorial, you will learn, how to run shell command in python. So let’s move forward.

Python Run Shell Command On Windows

What is Shell ?

• In computer science shell is generally seen as a piece of software that provides an interface for a user to some other software or the operating system.
• So the shell can be an interface between the operating system and the services of the kernel of this operating system

Python Modules For Running Shell command

Python provides lots of modules for executing different operations related to operating system.

Generally there are two important modules which are used to run shell command in python.

• Subprocess module
• OS module

Python Run Shell Command Using Subprocess module

The subprocess module allows you to spawn new processes, connect to their input/output/error pipes, and obtain their return codes. This module intends to replace several older modules and functions:

• os.system
• os.spawn*
• os.popen*
• popen2.*
• commands.*

The subprocess module allows users to communicate from their Python script to a terminal like bash or cmd.exe.

Now we will see different functions of subprocess module.

subprocess.call()

call() method create a separate process and run provided command in this process.

Write the following code to implement call() method of subprocess module.

Output

Python Run Shell Command Using OS module

The OS module is used to interact with underlying operating system in several different ways.

OS is an python built-in module so we don’t need to install any third party module. The os module allows platform independent programming by providing abstract methods.

Executing Shell scripts with os.system()

The most straight forward approach to run a shell command is by using os.system().

Capturing Output

The problem with this approach is in its inflexibility since you can’t even get the resulting output as a variable. os.system() doesn’t return the result of the called shell commands. So if you want to capture output then you have to use os.popen() method.

The os.popen() command opens a pipe from or to the command line. This means that we can access the stream within Python. This is useful since you can now get the output as a variable. Now let’s see it practically, so write the following code.
