Updating it can break certain tools that our operating system needs for essential tasks, including dependency management software. In cases where older are versions present, it is unsafe to update system python directly. In other cases, the command above could fail completely, indicting that python is not installed at all. If you use HomeBrew to install Python, you could uninstall running the following command.The output above indicates that the system version of python installed is much older than 3.7. It is possible that before needing a different version of python you choose to update your Python version. If you want to know more about how to setup Fish in your local environment, the article Improve your shell using Fish and Oh My Fish is precisely what you need. I am running a macOS High Sierra 10.13.3, this specific version came with Python 2.7.10, which is a legacy version.Īs an add-on, in this article, I will use a specific solution to setup an environment to run Python using Fish Shell.

Assumptionsįor this article, I will use my environment as an example. Regarding the materials available to learn about Data Science and Machine Learning you need the ability to switch between those Python versions, and that is precisely what I want to cover in this blog post.

Python 2.x is the legacy version, and Python 3.x is the present and future of Python, but some of the less disruptive improvements in 3.0 and 3.1 have been backported to 2.6 and 2.7, respectively. Python has two versions actively used, Python 2.x and 3.x. One of the blockers I quickly faced related to my environment. These are not only related to data manipulation and statistic concepts, but they are also connected in terms of what program language is commonly used, which is Python. In fact, in my opinion Data Science could be considered almost a prerequisite for Machine Learning. Last few months I have been delving into Data Science and Machine Learning.īoth fields are related.
