Install Python and set up working environment.

Introduction 

Taking an overview of Python's programming language and learning about its history and releases - in the previous chapter - this chapter will guide you on how to install Python on your operating system and setting up the environment.

The software needed to write and implement programs during your educational journey. The things we'll highlight are: installing Python 3 and then setting up its software environment that is setting up a fake environment that enables you to create an isolated space in your computer dedicated to Python projects, meaning that each project you work on has a set of credentials (dependencies) that will not affect other projects. This provides us with greater control over Python projects and the possibility of dealing with different versions of their packages. This is important when dealing with external packages. We will then create a simple programme featuring the phrase Hello World "(Welcome to the world! Famous, we will check the work of the environment is right, and then the way Python programs are created and implemented will become familiar to you from

Paves the way for writing and executing subsequent Python projects.

Choose from the following section of your computer operating system We tried to include the most famous operating systems

Linux, Windows and Mac have moved to follow the steps needed to implement the above.

1. Windows

Tighten this section step by step to how to install Payton (in Windows 10, install environment

Programming of its own across the command line.

a-prerequisite

You must have a device with Windows 10 connected to the network with the powers of a manager

(administrative access)

b-Open and set up PowerShell

We will perform most installation phases and settings via the command line, which is a non-graphic way to handle the computer, so instead of pressing the buttons, you will write a text and give it to the computer to execute it and it will show you a text output as well. Command line can help you modify or automate various tasks

on the computer every day, an essential tool for software developers.

PowerShell is a Microsoft software that provides a command line interface. Administrative tasks can be performed by implementing cmdlets, which pronounce "command lets", which are specialized items of the NET framework. It can perform operations that have made PowerShell open source since August

2016, now available via Windows and Unix systems (including Mac and Linux).

You'll find PowerShell by right-clicking on the Start icon in the bottom left corner of the

Screen. When the menu pops up, click "Search," then type PowerShell "in the search bar.

When offering you options right-click on the Windows PowerShell desktop app. "

Select Run as Administrator ". When a dialog box appears, ask you:

Do you want to allow this app to make changes to your PC?

Click on "Yes." Once you've done this, you'll see a text interface that looks like this:

We can switch the system folder by writing the following order:

cd ~

Then we'll go to the folder.

PS C:\Users\Sammy

Follow the installation process, we will prepare some permissions through PowerShell. Prepared

PowerShell to operate in the safest mode by default.

There are several levels of permissions, which you can set up as an administrator (administrator)

Restricted: Represents the default implementation policy, under this mode, you will not be able to implement scrapbites, and PowerShell will act as an interactive coincidence.

AllSigned : will enable you to execute all the scripts and setup files signed by a trusted entity, meaning that your device is likely to put you at risk of performing harmful scraps if they are signed by an unreliable side.

RemoteSigned: You will be able to execute the scrapbets and setup files posted from the network and signed on a reliable hand, which means you may put your device at risk of performing malicious scrapbites if those reliable scrapbooks are harmful.

Unrestricted: Allows all scrubs and setup files posted from the network to be implemented once you confirm that you realize that the file is home from the network. In this case, digital signatures are unnecessary, which means that it is likely to put your device at risk of implementing unreliable scrubs from the network that may be harmful.

We will use the implementation policy RemoteSigned to set the permission for the current user, and so on

We will allow PowerShell to accept the position scripts we trust, and without lowering all our defenses

Make permissions fragile as with the Unrestricted implementation policy. We will write at PowerShell

Set-ExecutionPolicy -Scope CurrentUser

PowerShell will ask you to specify the implementation policy, and since we want to use RemoteSigned We will write 

RemoteSigned

Once you hit the enter button, you will ask if you want to change the implementation policy. Type the letter and choose "Yes." Adopting changes we can verify the success of the process by requesting current authorizations in the device by writing

  Get-ExecutionPolicy -List 

You will receive outputs similar to:

        Scope ExecutionPolicy
        ----- ---------------
MachinePolicy             Undefined               
UserPolicy                Undefined               
Process                   Undefined               
CurrentUser               RemoteSigned            
LocalMachine              Undefined              

This confirms that the current user can execute reliable scraps that have come off the grid. We can now download the files we will need to set up Python programming environment.
