This is an introduction to Python for first year engineering students. We are writing this manual for first year engineering students who need to know basic programming. Typically this will be in an introduction to engineering course. The goal is to get you up and running programs as quickly as possible. We will give you all the building blocks to create advanced programs. Programs can be copy and pasted to your editor from the web page. Why Python? Python is capable of infinitely more than what is covered in this tutorial. It is used in web applications, science, and machine learning (artificial intelligence). Even though C++ runs faster, Python development times are much faster. Python is friendly.
We do not cover OOP (Object Oriented Programming) in this manual. OOP adds unnecessary complexity to the first year student. Probably all programs you write as an undergraduate student do not require Object Oriented Programming. Completing Chapter 1 through Chapter 11 are all that are required to write most undergraduate engineering programs. Later chapters are for reference. The final chapters are engineering discipline examples.
The target audience includes first year chemical, mechanical, petroleum, civil, electrical, and industrial engineers.
All programs will be completed on the PyCharm Community interface, which can be installed for free. PyCharm runs on Windows, Linux, and macOS. PyCharm requires 8GB of memory on a Windows computer. This tutorial covers installation on a Windows computer. However the programs run the same once PyCharm is installed.
IMPORTANT: All paragraphs of code are stand alone. You can copy and paste then into PyCharm and have them work.
All code has been tested. Two cautions after copy and pasting code from any source.
FIRST: There is always an issue with quote marks when you copy and paste. There are two types of quote marks,
depending on the font. Curly quote marks and straight quote marks. Only straight quote marks work in PyCharm. If
in doubt retype quote marks in the PyCharm editor.
SECOND: Indentation is significant and important in Python. If the code does not run correctly after copy and
pasting to PyCharm, check the indentations.
