I can't download and install pyhton

I am using Allwinner F113 (MangoPi MQ-R board) and it includes Tina-Linux(BusyBox). I want to dowloand python but wget keeps giving error response.

root@TinaLinux:/# wget https://www.python.org/ftp/python/3.9.1/Python-3.9.1.tgz
wget: not an http or ftp url: https://www.python.org/ftp/python/3.9.1/Python-3.9.1.tgz

How can install pyhton?
How can I download a data from a website with HTTPS ?

And second problem, tina linux has not a package manager. What is the equivalent of the sudo command in debian in tina linux?
