Sep 06, 2021 Python 3 For Mac v3.9.7 Best High-Level General Purpose Programming Language software, free download. Hy friends, today I will share with you the best and advanced programming language software for Mac OS. Did you know that Python is a programming language that lets you work more quickly and integrate your systems more effectively? 1) Open up Python official download site. It looks something like the image below. Press Download Python 3.7.4 or the version you would like to download. 2) After downloading the installer, open it to install Python 3. Python 3.7.4 installer Read Me contains the following note about Python 3 and Python 2 Co-existence.

Introduction

Python is a high level, dynamic, general purpose language. It was developed by Guido Van Rossum in 1991. Python's syntax allows developers to use fewer lines of code than any other programming language. It basically focuses on the code readability of program. Python 2.7 is installed by default on MacOS but we can install other versions like python 3.5 and 3.6.

In this tutorial, we are learning how to install Python 3.6.3 on the MAC Operating system.

Prerequisites

  • MacOS
  • Login as an administrator on terminal

Installation

Download

There are following steps which are used while installing Python3 on MacOS.

1) Checking python's version on the system

We can check which version of the Python is currently installed on our system. Generally, Python 2.7 is installed by default.

Let's see how can we do it.

Mac

It shows Python 2.7.10 is installed on the computer which is quite often.

2) Download Python 3.6.3

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

3) Install Python 3.6.3

Since the downloaded file already is in .pkg format hence no mounting is required and We can use installer command to install Python 3.6.3.

Let's see how can we do it.

Since The installer is used with super user permissions hence sudo forces terminal to prompt the user to fill the admin password. The process installs the Python 3.6.3 to the root directory which is mentioned with the target option.

4) Verify Python3

To check which Python version is installed on the machine, we can use python -version command. Since by default installed version is Python 2.7.10 hence it shows python 2.7.10. but it gives us flexibility to check the version of Python 3 on our computer.

Let's see how can we use python 3 to check which version of python 3 is running.

5) Working on Python's script mode

To work on Python command line, we simply type python3 on the terminal. Python shell open where we can run Python statements such as print statements as we did here.

To run a Python file (.py) on the terminal, we simply type the file name and the file will be interpreted.

Well, we have installed Python3 on our MacOS.

PythonMac

You can install Anaconda using either the graphical installer (“wizard”) or thecommand line (“manual”) instructions below. If you are unsure, choose the graphical install.

macOS graphical install¶

  1. Download the graphical macOS installer for your version of Python.

  2. RECOMMENDED: Verify data integrity with SHA-256.For more information on hashes, see What about cryptographic hash verification?

  3. Double-click the downloaded file and click continue to start the installation.

  4. Answer the prompts on the Introduction, Read Me, and License screens.

  5. Click the Install button to install Anaconda in your ~/opt directory (recommended):

  6. OR, click the Change Install Location button to install in another location (not recommended).

    On the Destination Select screen, select Install for me only.

    Note

    If you get the error message “You cannot install Anaconda in this location,” reselect Install for me only.

  7. Click the continue button.

  8. Optional: To install PyCharm for Anaconda, click on the link to https://www.anaconda.com/pycharm.

    Or to install Anaconda without PyCharm, click the Continue button.

  9. A successful installation displays the following screen:

  10. Verify your installation.

Using the command-line install¶

Use this method if you prefer to use a terminal window.

  1. In your browser, download the command-line version of themacOS installer for your system.

  2. RECOMMENDED: Verify data integrity with SHA-256.For more information on hash verification, see cryptographic hash validation.

    • Open a terminal and run the following:

    Note

    Replace /path/filename with your installation’s path and filename.

  3. Install for Python 3.7 or 2.7:

    • For Python 3.7 enter the following:

    • For Python 2.7, open the Terminal.app or iTerm2 terminal application and then enter the following:

    Note

    Include the bash command regardless of whether or not you are using the Bash shell.

    Note

    Replace ~/Downloads with your actual path and Anaconda3-2020.02-MacOSX-x86_64.sh with actual name of the file you downloaded.

  4. The installer prompts “In order to continue the installation process, please review the license agreement.”Click Enter to view the license terms.

  5. Scroll to the bottom of the license terms and enter yes to agree to them.

  6. The installer prompts you to Press Enter to confirm the location, Press CTRL-C to cancel the installationor specify an alternate installation directory. If you confirm the default location,it will display PREFIX=/home/<user>/anaconda<2or3> and continue the installation.

    Note

    Unlike the graphical install, installing the shell file will place it in ~/anaconda<2 or 3> by default,not ~/opt. This is due to limitations with installing .pkg files on macOS Catalina.

    Installation may take a few minutes to complete.

    Note

    We recommend you accept the default install location. Do not choose the path as /usr for theAnaconda/Miniconda installation.

  7. The installer prompts “Do you wish the installer to initialize Anaconda3by running conda init?” We recommend “yes”.

    Note

    If you enter “no”, then conda will not modify your shell scripts at all.In order to initialize after the installation process is done, first runsource<pathtoconda>/bin/activate and then run condainit.

    Note

    If you are on macOS Catalina, the new default shell is zsh.You will instead need to run source<pathtoconda>/bin/activatefollowed by condainitzsh.

  8. The installer displays “Thank you for installing Anaconda!”

  9. Optional: The installer describes the partnership between Anaconda and JetBrains andprovides a link to install PyCharm for Anaconda athttps://www.anaconda.com/pycharm.

  10. Close and open your terminal window for the Anaconda installation to take effect.

  11. To control whether or not each shell session has the base environmentactivated or not, run condaconfig--setauto_activate_baseFalseorTrue. To run conda from anywhere without having the base environmentactivated by default, use condaconfig--setauto_activate_baseFalse.This only works if you have run condainit first.

    Note

    condainit is available in conda versions 4.6.12 and later.

  12. Verify your installation.
