How to check if video has been deleted or removed in youtube using python

[jehoshua]

Changing the interpreter system wide can result into unexpected bugs.
For example if there is a Python2-Only script on the system and incompatible to Python 3,
then it won't run. I'm not sure if all os-specific tools do have Python 3 support.
Better is, if you change your local environment.

pyenv global system
pyenv local 3.8.1

Then try again to run python.

Thanks, I did the following

:~$ pyenv global system
:~$ pyenv local 3.8.1
:~$ python
Python 2.7.12 (default, Oct  8 2019, 14:14:10) 
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> exit()
:~$ 

Possibly if I determine what python packages are dependant upon version 2.7.12, and remove those packages if they are not required ? Then uninstall python version 2.7.12. Sounds messy, I'm in the process if updating the OS, so will do that as a matter of course.
