i needed gcc on a system i was working with.
not sure if 'gcc' can just be added to step 2.
i just did 'sudo zypper install gcc' and it worked fine.

Nicely worked on open suse 42.2, since i struggled lot to install python3.6 since open suse does not have 3.6 rpms to install quickly, Ofcourse gcc is must most of the applications to install. Also source compilazation and installation i tried: Python-3.6.11.tgz did not go well.

Yes, gcc is required in order to be able to compile Python from sources. Added gcc to step 2 to make this requirement explicit

The latest Python 3.6 release is 3.6.13, so it's probably best to replace all reference of 3.6.3 with 3.6.13 to get all the latest fixes.

For Ubuntu line 13 becomes:

sudo apt install libreadline-dev libsqlite3-dev libbz2-dev zlib1g-dev libssl-dev libffi-dev gcc
