@satineeraj I just have to ask, why would you join an AutoIt (which works only on Windows) scripting forum, to ask a question about installing Python on Ubuntu?

Have you ever tried to simply enter your question "Install Python on Ubuntu" in a search engine of your trust?

One gets various instructions regarding the installation, e.g. install-python-ubuntu

sudo apt-get update

before ? :rolleyes:

and check if your OS is up to date:

sudo apt-get upgrade

But you should just install some distrib within Anaconda or MiniConda or w/e exists (might be the 'smartest' choice, as there's not so much people using python without any learning / dataframe toolkit).

Anyway, i thought Python3 was installed by default on Ubuntu now  ...

You probably didn’t get the prerequisites 

actually download it

Install it and then compile it. This isn’t windows

LOL, OP said Ubuntu not Gentoo :P

And even Gentoo provides automated builds for popular software packages.


Anyway, the issue is OP calling python without using any sort of suffix, the newer versions of Ubuntu don't install the default symlink for python3, so you have two choices:

1. Call python3 instead, this approach is recommended because it makes it clear that you have migrated to the new Python.

2. Install the python-is-python3 package which will provide a symlink to python3, now you can call python and all operations will magically redirect to Python 3. You can also do the same trick with Python 2 but it's a bad idea unless you know what you are doing.
