• A USB flash drive or other secondary volume, formatted as Mac OS Extended, with at least 12GB of available storage
• A downloaded installer for macOS Big Sur, Catalina, Mojave, High Sierra, or El Capitan

Download macOS

• Download: macOS Big Sur, macOS Catalina, macOS Mojave, or macOS High Sierra
  These download to your Applications folder as an app named Install macOS [version name]. If the installer opens after downloading, quit it without continuing installation. To get the correct installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.
• Download: OS X El Capitan
  This downloads as a disk image named InstallMacOSX.dmg. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. You will create the bootable installer from this app, not from the disk image or .pkg installer.

Use the 'createinstallmedia' command in Terminal

1. Connect the USB flash drive or other volume that you're using for the bootable installer.
2. Open Terminal, which is in the Utilities folder of your Applications folder.
3. Type or paste one of the following commands in Terminal. These assume that the installer is in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace MyVolume in these commands with the name of your volume.

Big Sur:*

Catalina:*

Mojave:*

High Sierra:*

El Capitan:

* If your Mac is using macOS Sierra or earlier, include the --applicationpath argument and installer path, similar to the way this is done in the command for El Capitan.

After typing the command:

1. Press Return to enter the command.
2. When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
3. When prompted, type Y to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the volume is erased.
4. After the volume is erased, you may see an alert that Terminal would like to access files on a removable volume. Click OK to allow the copy to proceed.
5. When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Big Sur. You can now quit Terminal and eject the volume.

A bootable installer doesn't download macOS from the internet, but it does require an internet connection to get firmware and other information specific to the Mac model.

Hey Shouters!! Today we will learn how to install python IDLE editor in Windows, Linux, and Mac operating systems.

What is the Python Language?

Python is one of the fastest programming languages. It was created by Guido Van Rossum in 1989. Python is named after a very popular BBC comedy show Monty Python’s Flying Circus. Python IDLE is free software.

It is a simple and very powerful general-purpose computer programming language. Python is a high-level language, interpreted language with easy syntax and dynamic semantics.

What is IDLE in Python?

IDLE is an integrated development environment for python, which has been bundled with the default installation of the language. IDLE can be used to execute a single statement just like a python shell and also to create, modify, and execute a python script.

Open IDLE is bundled with python for development purposes. Python is also an interpreted language, meaning you don’t need to learn how to compile code into machine language.

Installing Python IDLE On Windows-

Step-1: Python is available on its website Python.org. Hove the mouse on the downloads menu and then on the windows option and click on the button for the latest release.

CLICK TO PYTHON 3.7.4 AS SHOWN BELOW.

Step 2: Click on download button Windows x86-64 executable installer.

After you have successfully downloaded the IDLE in windows. To check that it is completely installed. Follow the below steps.

1. Navigate the directory where you have selected to install the file.

2. Double click on the file/icon python.exe.

3. The following pop-up window will appear:

Installing Python IDLE On MAC –

Step 1: We can check the version of python currently installed on the system. Generally, Python 2.7 is installed by default in Mac.

If to install Python 3.6.3, we have to download the latest version from its official website https://www.python.org/downloads/ . The file must be downloaded in .pkg format which can be directly installed by using Installer command.

Step 2: The MacOs Terminal is an application you can use to access the command-line interface. Like many other applications, you can find it by clicking on finder, navigation. To application folder and then further, utilize that folder. That means while instead of clicking on buttons you would type text and receive feedback instantly.

INSTALL PYTHON 3.6.3 –

Although the downloaded file already is in .pkg format so no mounting is required and We can use installer command to install Python 3.6.3. Now the installer is used with super user permissions hence sudo forces terminal to prompt the user to fill the admin password.

How To Check Python IDLE On Mac-

To check for a Python version installation on the machine, we can use python -version command. Since by default installed version is Python 2.7.10 therefore it will show python 2.7.10. But it gives us more flexibility to check the version of Python 3 on our computer.

$ python-version

 WORKING ON PYTHON’S SCRIPT MODE

To work on Python command line, simply type python3 on the terminal area. On python shell we can write any of problem to get output. The format is as below:

To run a python file (.py) is the extension, to save file simply type file name along with the extension.

Finally, Python 3 is installed in Mac Os. You are ready to run python and learn to program.

INSTALLATION PYTHON IDLE ON LINUX

Some version of Linux come with python is been installed. If you have Red hat package manager based distribution, you already have python on your system and don’t need anything else.

Depending on the version of Linux you use the version of python varies. You have two ways to use to install python on Linux. The first way works on any Linux distribution and the second way has different criteria that you need.

Step 1- First of all install the development package which is required to build python.

Installation In Debian-

$ SUDO APT UPDATE
$ SUDO APT INSTALL BUILD-ESSENTIAL ZLIB1G-DEV
LIBNCURSES5-DEV LIBGDBM-DEV LIBNSS3-DEV
LIBSSL-DEV LIBREADLINE-DEV LIBFFI-DEV CURL

Installation In Fedora:

$ sudo dnf group install development

Step 2. Download the latest release of Python 3

Next, we want to check the system has proper tools to build python3. Go to the official website for the latest version and after the download is completed, you have .tar.xz archive file which is a “tarball” contains source code of python.

Step 3– Extract the Tarball

The moment the download is completed, extract the tarball using extractor application of your choice or Linux tar command.

$ tar–xf Python-3.?.?.tar.xz

Step 4- Configure the Script

Once the python tarball is extracted, navigate to configure the script and execute it in your Linux terminal. The configuration process may take several times to complete the configuration process, wait until it’s been done.

$ cd Python-3.*
./configure

Step 5- Start the build process

If you already have a python version installed in your system, then you have installed new version alongside by using below command;

$ sudomakealtinstall

The process takes a few times, If you want to replace the current version of python, you can replace or uninstall your current python package using the package manager and then install it. Since installing python into usr/bin, you need to run as root.

$ sudomakeinstall

Note: Mandatory to use alt install target to make. By using the install target will overwrite python binary.

Step 6- Verify installation process

If there is no encountered any errors, the latest python is now successfully installed on your Linux system. To verify it, Write the below command in your terminal.

python3 –version

After installing the python, try to run some basic programs.
