~~~~~~~~~~~~~~~~
|

|

If you're choosing a Python interpreter to use, I *highly* recommend you use
|
||||
Python 2.7.x, unless you have a strong reason not to.
|
||||
If you're choosing a Python interpreter to use, I recommend you use the
|
||||
newest Python 3.x, since every version brings new and improved standard
|
||||
library modules, security and bug fixes.
|
||||
|
||||
Also use Python 2.7.x if you're starting to work on a new Python module. If you
|
||||
have managed to get it working on 2.7, you can add support for older 2.x
|
||||
versions.
|
||||
Only use Python 3 if you have a strong reason to, such as a Python 2
|
||||
exclusive library which has no adequate, Python 3 ready alternative. Use
|
||||
`Can I Use Python 3? <https://caniusepython3.com/>` to check if this is
|
||||
the case.

The Future (Python 3)
|

~~~~~~~~~~~~~~~~~~~~~
|

|
||||
Python 2.x is the status quo, Python 3.x is the shiny new thing.
|
||||
Python 2.x is legacy, Python 3.x is the present and future of the language

|

|
||||
The difference between Python 3 and Python 2 is much greater, therefore
|
||||
writing code that works in both Python 2 and Python 3 is a very complicated
|
||||
process.
|
||||
|
||||
It is possible to `write code that works on Python 2.6, 2.7 and 3.3
