debian – Installing the Python version from .tar.xz

I'm using a Linux distribution based on debian, and I'm trying to update the python version from 3.5.3 to 3.7.3. I used wget to download the .tar.xz file from the python website, but I'm not sure how to install it, so when you type & # 39; python3 –version & # 39; appear 3.7.3 instead of 3.5.3. I tried installing it using & sudo make install & # 39 ;, but that did not work.
