The author has been very selective about what topics to cover in this short step by step manual for first year engineering students. The first eleven chapters cover what you must know. This is based on personal experience as a petroleum engineer. The reader needs little or no programming experience. The best part is you can learn to program in Python for FREE! The Python programming language and the professional PyCharm Community user interface are free downloads. All that is required is a Windows computer with 8GB RAM. (Most 4GB computers can be inexpensively upgraded to 8GB.) Chapters 12 thru 16 cover topics that you may need, or are good to know if reading other programmer's Python code. Chapters 17 thru 20 contain more advanced Python examples of practical applications in engineering.
