My MacBook came preinstalled with Python 2.7.16, and I downloaded Python 3.8.5. To my understanding, the operating system needs Python 2.x so I did not uninstall it.
Eclipse (using Pydev) is the IDE I'm using.
I set up two interpreters, one for python
and the other python3
.
I set up one project for each interpreter to make sure I set them up correctly.
The script is:
import sys
print(sys.version)
When I run it with the python
interpreter, I correctly get version 2.7.16.
When I run it with the python3
interpreter, I instead get 3.8.2.
Running python -V
yields ``Python 2.7.16. Running
python3 -Vyields
Python 3.8.5```.
Why does the interpreter return one version and the terminal another?
I'm at a loss for how to troubleshoot or fix this, or if it is a non-issue.

To clarify, you get the 2.7.16 and 3.8.2 versions when running your program from within Eclipse. The python -V is clearly from the command line. The interpretation is that your Eclipse environment came with its own python interpreter which happened to be 3.8.2. Have you tried running your script from the command line with python3 path/to/your/script.py
? This probably gives 3.8.5. I don't see a real problem here in most cases you do not care whether you have python 3.8.2 or 3.8.5.
The "biggest" issue is a cosmetic one that you have two python3 installations which is a bit of a waste. When using additional libraries, you may find that you have to install them in your Eclipse environment and in your command line if you want to use your scripts in both environments which would be a bit tedious. If this does turn out to be a problem, check in Eclipse whether there is any way to change your python3 configuration to use the interpreter used by the command line (sorry cannot be more specific, it's a long time that I used Eclipse).
