Python Basics

1. Number

   • Integer

       • They can be as long as you want, depending on your memory capacity.
   • Floating-point numbers

3. Boolean

   • It can interpret falsehood or truthness; so there are two different values.

4. Variables and Constants

   • Divided in Boolean, Text and Numerical

5. Arithmetical operations

   • In python there are different mathematical operations, as addition (+), subtraction (-), multiplication (*), division (/), modulus (%), exponentiation (* *).

6. Comments

   • Is a piece of text in the program coding as it is not executed; it provides additional info about the code and it is identified because it is written after a #.
