title: How to use pip for python 3.9 instead of inbuilt python 3.8 in Ubuntu?
body: <p>Today I faced a problem regarding pip3 in Ubuntu. Ubuntu comes with python 3.8 but I wanted to use latest versions of python, like 3.9 or maybe 3.10. So I installed it using 'ppa:deadsnakes' repository and also installed pip. But the problem is I want to use pip in python 3.9 instead of version 3.8. So I changed the default python version to 3.9 and everything crashed.
  So reverted to python 3.8. Whenever I install some package it gets installed using python 3.8.
  Help me, how can I use python 3.9 pip and install packages in python 3.9 without changing the default version.
  Any help is appreciated.</p>
  <p>--&gt; Thing I want is that when I want to install python package using
  <code>pip3 install &lt;package_name&gt;</code> it must install in python3.9 and not in python3.8</p>
