Recently I’ve been enrolled myself into Udacity’s AI programming with Python. Before my class officially start, I want to get myself familiarized with Python’s programming syntax. I proceeded to download Python on my Mac to fiddle around with the REPL.
It’s important to note that OSX ships with Python 2 by default. However, since I’m picking up Python, I’ve proceeded to download the latest version of Python instead.
Before we get started on Python’s installation, we’ll need to have homebrew installed. If you do not have homebrew installed on your mac, you can follow the installation process here.
1. Installing Python
To get started, we will simply type the following in our terminal.
brew install python
2. Installing pip
pip is one of the more popular Python package managers out there. We’ll need pip in order to install virtualenv.
curl -O http://python-distribute.org/distribute_setup.py python distribute_setup.py curl -O https://raw.github.com/pypa/pip/master/contrib/get-pip.py python get-pip.py
3. Installing virtualenv
virtualenv is a tool to create isolated Python environments. With this, we can easily access different versions of Python for projects with different Python version. You can find out more about virtualenv and it’s documentation here.
pip install virtualenv
After the installation, we can easily access Python 3 using
If you want to use python 2 instead, you can access it using ‘python2’.
And that’s all! Go and explore the world of Python!
