What is var

Question

Is it a function?

Answer 1

Let me just make a short remark to the post of Rik Wittkopp. There are some limitations in naming for variables. They can not start with a number and they can not contain any spaces / blancs. And keep in mind that python is case sensitive - that means that upper or lowecase matters.

Answer 2

Var is short for variable, which is why it is used in the lesson modules.
Examples of variables are:
x = 6
y = 7
z = x + y
x, y & z are all variables. 6 & 7 are the values assigned to the variables.
A variable can be written however you want, it is there to allow you to process the values
