How to Find the Installation Location of Python3 on Your Mac?

Location of Python3 Installation

By default, Python3 is installed in the user’s AppData directory located at C:\Users\[Username]\AppData\Local\Programs\Python\Python37. This directory can be easily accessible by opening File Explorer and entering %appdata% in the address bar. If you wish to place Python in a higher-level directory, such as C:\Python3.7, you can do so during the installation process or manually move the existing installation after it has been completed.

Is Python3 Installed on Mac?

Yes, Python 3 is likely pre-installed on your Mac. To check if it’s installed, go to Applications > Utilities and click on Terminal. You can also press Command + Spacebar, type terminal, and then press Enter. If you have Python 3.4 or later installed, you’re all set to use the pre-installed version of Python.

Enabling Python3 on Mac

Enabling Python3 on Mac is relatively straightforward once you have installed the necessary prerequisites. First, you’ll need to install Xcode, which is Apple’s Integrated Development Environment (IDE). You can download Xcode from the App Store. Once Xcode has been installed, you’ll need to install Homebrew. Homebrew is a package manager that installs the stuff you need, such as Python3. To install Homebrew, open Terminal and enter the following command: /bin/bash -c “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)”

Once Homebrew has been installed, enter “brew install python3″ into the Terminal to begin installing Python3. After installation is complete, you may want to add Python3 to your PATH environment so that it can be accessed by other applications. To do this, run the following command in Terminal: export PATH=”/usr/local/opt/python/libexec/bin:$PATH”. This will add the path for Python3 to your PATH environment variable and enable access for other applications.

That’s it! You should now have Python3 enabled on your Mac.

Checking if Python 3.8 is Installed on Mac

You can easily check if Python 3.8 is installed on your Mac by launching the Terminal application and typing “python3” into it. If Python 3.8 is installed, you will get a response from Python with its version number (3.8). You can also enter “python –version” to get more specific information about which version of Python is installed. If you do not see a response indicating that Python 3.8 is installed, it means that you need to install it before you can use it on your Mac.

Changing the Default Python 3 on Mac

The first step is to install Python 3 on your Mac using Homebrew. Homebrew is a package manager for Mac OS, and it makes the installation process simpler and more convenient than manually downloading and installing Python. To install Python 3 with Homebrew, open your terminal (bash or zsh) and run the following command:

`$ brew install python3`

Once the installation process is complete, you can check where Python 3 was installed by running the following command:

`$ which python3`

This will print out the path to your Python 3 executable. Now that you have installed Python 3 and determined its location, you can change the default Python symlink to use the version of Python you want. To do this, run the following command in your terminal (substituting the actual path from the ‘which’ command):

`$ sudo ln -s [PATH TO PYTHON] /usr/local/bin/python3`

This will create a new symlink pointing to your desired version of Python at /usr/local/bin/python3. Finally, check that it worked by running:

`$ python3 –version`

If everything worked correctly it should print out the version number of your newly set default version of Python 3.

Checking if a Python 3 Module is Installed

To determine if a Python 3 module is installed, you can use the ‘pip list’ command. This will list all of the installed modules and their version numbers. You can then cross-reference this list with the module you are interested in to see if it is installed. Alternatively, you can also use the ‘pip freeze’ command, which will output a complete list of all installed modules and their versions in a single-line format.

Location of Python Library

The Python library is typically located in the site-packages folder within the Python install directory, however, if it is not there or you are uncertain where it is installed, you can use this Python sample to locate Python modules installed on your computer. To do so, open a command prompt window and type:

python -c “import sys; print(‘\n’.join(sys.path))”

This will print a list of folders that are part of your Python installation path. If you see the library you are looking for in any of them, then that will be the path to your library. If it’s not there, then the library may have been installed elsewhere and you should check other potential locations such as the user profile folder or other folders on your system.

Checking if Pip3 is Installed on a Mac

Pip3 is a package manager for Python 3, and it is included by default with Python 3 installations on Mac. To check if pip3 is installed on your Mac, open the Terminal app. In the Terminal, type `pip3 –version` and press Enter. This will show you the version of pip3 that is installed on your machine. Alternatively, type `python -m pip –version` and press Enter to view the version of pip that is associated with your currently installed version of Python. If you get an error message in response to either command, then it means that pip3 is not installed on your Mac and you will need to install it before you can use it.

Installing Python3 on Mac Terminal

Installing Python3 in Mac Terminal is a simple process that can be accomplished with a few steps.

Step 1: Open the Terminal application.
Step 2: Update and upgrade Homebrew with the following command: brew update && brew upgrade.
Step 3: Install Python3 using this command: brew installs python3.
Step 4: Once installation is complete, you can verify that Python3 is installed by entering the following command in the terminal: python3 –version. This should display the version of Python3 that was installed in your system.

That’s it! You have successfully installed Python3 in Mac Terminal.

Running Python3 Code on Mac Terminal

Running Python 3 code on a Mac terminal is easy and straightforward. First, open Launchpad and search for Terminal. Once the terminal is open, type ‘python3’ and press enter. This will bring up a prompt with the version of Python installed on your machine. You may then enter your code line-by-line, or you can type in a program file name to execute a script from a text file. To run the code directly from the command line, type ‘python3 ’ which is replaced by the name of your source code file (for example python3 myscript.py). If you want to see the output of the program, add ‘print()’ statements at various points in your code and use ‘python3 -u ‘ to view all outputs as they are generated. Finally, you can also use an IDE such as PyCharm or Visual Studio Code to write programs and run them from within your editor window.

Conclusion

In conclusion, Python3 can be installed on Macs through the Xcode development environment, or through Homebrew Package Manager. Once installed, the interpreter can be accessed and used in the command line of your terminal. Additionally, if desired, you can also add Python to your PATH environment variable which will make it easier to call the interpreter from anywhere.
