I have noticed that yum install python3 or apt-get install python3 python 3.6 but I am unable to understand why it installs this specific version; 3.8 is the latest version of python. Why does it pick 3.6 in specific ?
This just depends on the OS you are using. Each OS packages a certain version of python and sticks with it. For example:
CentOS 7: python 3.6
CentOS 8: python 3.6
Ubuntu 16.04: python 3.5
Ubuntu 18.04: python 3.6
Ubuntu 20.04: python 3.8
NOTE: There are some OS that use rolling releases and that thus will update their default python version, but that is more rare.

I have python 3.8 as the default install with ubuntu 20.04.
I have upgraded to python 3.11.
However, if i do pip3 --version is see this:
pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8)
In windows i just do pip install <package> and i want to achieve the same level of simplicity in ubuntu.
How to get this to upgrade too (python 3.11) or whatever the latest version of python is in Ubuntu ?
When I try to install, it says that 2.7 is already installed. I want Python 3. How to install that?
I tried using python3, cannot find package:
Python 3 is a different package:

Python 3.7.6
Ubuntu 14.14 server itself has installed Python 3.4 in default, however, I need to use Python 3.5 for certain packages. So I install it by myself.
The problem is that every time I try to install packages by running "pip3 install xxx". It always installs under Python 3.4 rather than 3.5.
Please show me some lights on how to use Python 3.5 properly on Ubuntu. Many thanks for any good suggestions!
To install it to the right version of python, type:
sudo python3 -m pip install [package]
Now this is assuming the name of Python 3.5 is python3.
If this is not the case,
Create an alias of Python 3.5 to some name
Replace python3 in the snippent above with that name.
Execute the command.
I have a remote machine with Python 2.6 installed. I then installed python 2.7 using these instructions python install. I then set up an alias so scripts will use 2.7 in future.
How do I install numpy to python 2.7.
python2.7 -m pip install numpy
Should do the trick
So I just installed Python 2.7 in my Macbook Pro.
The problem is I installed virtualenvwrapper, pip, virtualenv and many other packages in Python 2.6 and the binaries are in /usr/local/bin.
What I want to do then is install the aforementioned packages for Python 2.7 and use them instead of the packages from Python 2.6.
How do I do this?
Install them in 2.7.
python2.7 setup.py install
