Getting error "/usr/bin/python3.9: bad interpreter: No such file or directory" after installing pip in ubuntu 16.04

Question

I installed python3.9 in ubuntu and also make it default which creates some problems. So I again make python 3.5 as default and removed python 3.9.

Then I tried to install pip by using command:

sudo apt-get install python3-pip

and it installed successfully but when I ran:

pip3 --version

it gives me this error:

/usr/bin/python3.9: bad interpreter: No such file or directory

I don't know why I removed python 3.9 completely with all its dependencies then why pip is not installing properly?

Please help me out here i'm really stuck.

How did you install Python 3.9? It does not come with Ubuntu 16.04. — Klaus D., Jul 30 '21 at 11:55
Use pyenv/pipenv/venvs to prevent messing around with system's Python interpreter. — Maurice Meyer, Jul 30 '21 at 12:16

This answer might help, you can run pip as a module, try python3 -m pip [commands] to see if it works.
