1.Requirements:

yum install gcc openssl-devel bzip2-devel

2.Download Python 3.7:

cd /usr/src
wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz
tar xzf Python-3.7.0.tgz

Appreciate any and all help

Had same issue on Centos 7, it can be fixed by install some packages such as libffi-devel. If it does not work maybe try install the following:
yum install gcc openssl-devel bzip2-devel libffi-devel zlib-devel xz-devel

After installing these packages, you have to reinstall the version of python. It went well in my case. Hope it helps

You will need :
sudo yum install libffi-devel

That works perfectly AlmaLinux release 8.5
