The divide between Python 2 and 3 lasted a long time, and in recent years all of the new features were added to version 3. To help bridge the gap and extend the viability of version 2 Naftali Harris created Tauthon, a fork of Python 2 that backports features from Python 3. In this episode he explains his motivation for creating it, the process of maintaining it and backporting features, and the ways that it is being used by developers who are unable to make the leap. This was an interesting look at how things might have been if the elusive Python 2.8 had been created as a more gentle transition.

Did you know Data science is a fast-growing career field, with a 650% growth in jobs since 2012 and a median salary of around $125,000? Springboard has identified that data careers are going to shape the future, and has responded to that need by creating the Springboard School of Data, comprehensive, end-to-end data career programs that encompass data science, data analytics, data engineering, and machine learning.
Each Springboard course is 100% online and remote, and each course curriculum is tailored to fit the schedule of working professionals. This means flexible hours and a project-based methodology designed to get real world experience: every Springboard student graduates with a portfolio of projects to showcase their skills to potential employers. Springboard’s unique approach to learning is centered on the very simple idea that mentorship and one-on-one human support is the fastest and most efficient way to learn new skills. That’s why all of Springboard’s data courses are supported by a vast network of industry expert mentors, who are carefully vetted to ensure the right fit for each program. Mentors provide valuable guidance, coaching, and support to help keep Springboard students motivated through weekly, 1:1 video calls for the duration of the program.
Before graduation, Springboard’s career services team supports students in their job search, helping prepare them for interviews and networking, and facilitates their transition in the tech or data industry. Springboard’s tuition-back guarantee allows students to secure the role of their dreams and invest in themselves without risk. Meaning students are not charged if they don’t get a job offer in the field they study. Springboard’s support does not end when students graduate. All Springboard graduates benefit from an extensive support network encompassing career services, 1:1 career coaching, networking tips, resume assistance, interview prep, and salary negotiation.
Since Springboard was founded in 2013, around 94% of eligible graduates secured a job within one year, earning an average salary increase of $26,000. Want to learn more?

- Your host as usual is Tobias Macey and today I’m interviewing Naftali Harris about his work on Tauthon, a fork of Python 2 that backports features from Python 3
- How did you get introduced to Python?
- Can you start by describing what Tauthon is and your motivations for creating it?
- What’s the story behind the name?
- What types of applications and environments are you using Tauthon in?
- How much adoption of Tauthon have you seen?
- What are some of the different ways that your users are employing it?
- Is this the missing "2.8" release? In other words, is this intended to be a bridge for simplifying the migration of existing Python 2 code to Python 3, or as an extended support window for Python 2?
- What features have you backported from Python 3?
- What is your process for identifying and prioritizing features to bring into Tauthon?
- What is your workflow for implementing the backported functionality in Tauthon?
- What are some of the cases where you have had to compromise on the functionality or syntax of a feature that you have backported in order to fit into Python 2?
- What is your governing philosophy for how to manage syntax or behavior differences between Python 2 and 3?
- What have been the most challenging features to backport and maintain?
- What are some of the ways that Tauthon might break existing Python 2 code?
- What is the story for compatibility with libraries that are Python 3 only?
- What have you seen in terms of adoption of Tauthon?
- Do you have any sense of the commonalities among those users?
- What are some of the ecosystem challenges that faces users of Tauthon? (e.g. Pip support, package compatibility, etc.)
- What are some of the most interesting, unexpected, or challenging lessons that you have learned in the process of creating and maintaining Tauthon?
- What are your long-term plans for Tauthon, and how have they changed since you first started working on it?
