If you are using Ubuntu 20.04, usually, Python is already installed. To check:
python -v
#it shows: Python 3.8.5
If python is installed, run this:
whereis python3
#it shows: python3: /usr/bin/python3.8 /usr/bin/python3.8-config /usr/bin/python3 /usr/lib/python3.8 /usr/lib/python3.9 /usr/lib/python3 /etc/python3.8 /etc/python3 /usr/local/lib/python3.8 /usr/include/python3.8 /usr/share/python3 /usr/share/man/man1/python3.1.gz
Finally, create a symlink:
sudo ln -s /usr/bin/python3 /usr/bin/python
This should work.
