We want to run and develop software on our mac, for this we need to install Python.

  • 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“.
  • Using Python on a Macintosh — Python 3.9.7 documentation. Using Python on a Macintosh ¶. Python on a Macintosh running Mac OS X is in principle very similar to Python on any other Unix platform, but there are a number of additional features such as the IDE and the Package Manager that are worth pointing out.

As of writing this, I am using the latest version of Python on my machine: 3.8.5. It is usually fine to use the latest version. Except every now and then, something juicy requires an earlier.

Anaconda Individual Edition is the world’s most popular Python distribution platform with over 25 million users worldwide. You can trust in our long-term commitment to supporting the Anaconda open-source ecosystem, the platform of choice for Python data science. Python's website has a macOS Python 3 installer we can download and use. If we use the package installation, a python3 fill will be available in /usr/local/bin/. Aliasing is a must since the Python binary stored in /usr/bin/ can't be changed.

1. Download the most recent package from the Python website.

2. Double-click on the downloaded file to run the Python 3 installer.

  1. To build the image, run Docker build from a command line or terminal that is in the root directory of the application. Docker build -tag my-python-app. This will “tag” the image my-python-app and build it. After it is built, you can run the image as a container. Docker run -name python-app -p 5000:5000 my-python-app.
  2. When you install Python 3 on a Mac, it does not update the python command to use Python 3 instead of Python 2. Instead, to run Python 3, you have to use the python3 command. Here’s how to fix this: First, check your Python version: Nats-MBP: natdunn$ python -V Python 2.7.15. We want that to say python 3. What shell are you using? First, determine what shell you are using.
  3. Mac OS X 10.8 comes with Python 2.7 pre-installed by Apple. If you wish, you are invited to install the most recent version of Python 3 from the Python website (A current “universal binary” build of Python, which runs natively on the Mac’s new Intel and legacy PPC CPU’s, is available there.
  4. Python 2 is bundled with Mac OS X. However, Python 3 is not. We recommend that you download and install Python 3, and use Python 3 exclusively when running programs associated with this booksite. Perform these steps to download and install Python, IDLE, Tkinter, NumPy, and PyGame: Browse to the Python for Mac download page.

3. If you open the Applications folder, you’ll find a new Python 3.x folder.

4. Inside that folder you’ll find a GUI interface for launching Python applications, as well as IDLE, an IDE for developing Python applications.

Running Python 3

There are a couple ways that you can run Python 3 scripts on your Mac.

1. To run Python 3 from the Terminal, you’ll use the command python3. This is different from the python command which will load up Python 2.7.

2. That command, without any additional arguments, will invoke the Python 3 interactive interpreter.

3. If you want to run a script with the Python 3 interpreter, follow the python3command with the path to your .py file.

You can also run Python 3 programs from the Python Launcher GUI. For running a quick script from Terminal, using the Launcher doesn’t have any advantages, but if you want to set flags and options, this might be an easier way to go about it.

1. Open the Python Launcher found in “/Applications/Python 3.5.” (Note that the number in the Python folder may change with future versions.)

2. This will open a Preferences window. By default, the launcher will run everything with a Python 2 interpreter. To change this to Python 3, you’ll need to change the directory path under “Interpreter” to /usr/local/bin/python3. That is where the Python 3.5 interpreter is installed by default.

If you now type python --version, you'll notice that it says Python 2.7.6, that's because if you want to use Python 3, you must type: python3 --version

A simple safe way would be to use an alias:

How Do I Run Python

For Python:
cd ~ && echo 'python=python3.8' >> ~/.bashrc && echo 'python=python3.8' >> ~/.bash_aliases && echo 'python=python3.8' >> ~/.zshrc

For pip to pip3
cd ~ && echo 'pip=pip3' >> ~/.bashrc && echo 'pip=pip3' >> ~/.bash_aliases && echo 'pip=pip3' >> ~/.zshrc

After adding the above in the file, run the command below to refresh:
source ~/.bashrc && source ~/.bash_aliases && ~/.zshrc

To disable the alias in the current shell use the unalias built-in command:
unalias python

For pip: python -m pip install --upgrade pip

Bonus: Virtual Environments

You should always use a virtual environment for your Python projects. A virtual environment is a way to create an isolated space so you can, for example, run Python 2.7 for one project and Python 3.7 for another on the same computer. We can use the built-in venv module for this.

It’s a best practice to keep all your virtualenvs in one place. Let’s create a folder:
mkdir ~/.virtualenvs

Now create a new virtual environment called project1_env by running:
virtualenv -p python3 project1_env or if you are on windows: virtualenv project1_env

Activate VEnv

MAC:
Because we used python3 here our virtual environment knows that when we type python for a command we mean Python 3 not Python 2. In order to activate this virtual environment, so we can use it, we must also run the following command:
source project1_env/bin/activate

Windows
Virtualenv creates a batch file in your new venv envScriptsactivate.bat, you can enter it on the command line or simply drag and drop it in the terminal and hit enter.

Note that while the environment is active, you will see its name in parentheses. Software packages we install now will only be available within this virtual environment.

To stop using a virtual environment, either close the Terminal window or enter deactivate.

Save requirements

How To Run A File In Python

You can use the command pip freeze --local > requirements.txt to create a text file with the installed packages of that specific enviroment.

Install packages from saved requirements

To install the requirements you saved on that text file on the same or different virtual env., simply type pip install -r requirements.txt

Interviewer: And how long have you been here?
Camel spotter: Three years.
Interviewer: So, in, er, three years you've spotted no camels?
Camel spotter: Yes in only three years. Er, I tell a lie, four, be fair, five. I've been camel spotting for just the seven years. Before that of course I was a Yeti Spotter.
Interviewer: A Yeti Spotter, that must have been extremely interesting.
Camel spotter: Oh, it was extremely interesting, very, very - quite... it was dull; dull, dull, dull, oh God it was dull. Sitting in the Waterloo waiting room. Of course once you've seen one Yeti you've seen them all.
