At the Institute we use both Python 2 and Python 3. While researching the current differences (Python 3.5, compared to Python 2.7), I found two beautiful articles by Brett Cannon, the current manager of Python, and summarized them for my work group.
The relevant points for us1 are the following:
Why Python 3 was necessary:
Why use 3 (relevant for us, e.G. for new projects):
The effect of these points is much larger than this short text suggests: avoid surprises, avoid awkward workarounds, and easier debugging.
I have summarized them because I can not expect scientists (or other people who only use Python) to read the full articles, just to decide what they do when they get the channce to tackle a new project. ↩
Example for print():
nums = [1, 2, 3]
with open("data.csv", "a") as f:
print(*nums, sep=";", file=f) ↩
The European Copyright directive threatens online communication in Europe.
But thanks to massive shared action earlier this year, the European parliament can still prevent the problems. For each of the articles there are proposals which fix them. The parliamentarians (MEPs) just have to vote for them. And since they are under massive pressure from large media companies, that went as far as defaming those who took action as fake people, the MEPs need to hear your voice to know that your are real.
If you care about the future of the Internet in the EU, please Call your MEPs.
