I have been a software developer for 52 years, dealing primarily with systems level software on IBM Mainframes.

My programming language of choice is IBM's HLASM, my primary focus has been the operating system, VSE, MVS, Z/OS, the components I am familiar with are VTAM, VSAM, TCP/IP and HSM.

I am now faced with the need to learn Python 3.x, this is painful and not very pretty. Please bear with me as I try to start the learning process,
