“Begin at the beginning," the King said, very gravely, "and go on till you come to the end: then stop.”
― Lewis Carroll, Alice in Wonderland
What is Code? That is the all the buzz these days... Code. STEM (Science, Technology, Engineering and Math). If you don't know it you're left behind. It all started when a number of reports showed that the US is behind in STEM. There's a big push to catch up and this is a small part of it.
Code is short for Source Code and it means instructions in a language the computer understands.
Computer languages could be high level or low level.
High Level means that the language is mostly human-readable. Also there are usually easy short-cut ways to accomplish complicated tasks. Most programmers start with these languages and learn the ropes in a more understandable language.
Low Level languages are close to the machine's step-by-step instructions. These languages are very hard to read and everything must be done "by hand." Think of them as the raw-materials of programming. You have to mill your own lumber before you build a house with it.
Python is a high level language. It is easy to jump into and you don't have to learn a lot to get programming.
