Programming Language — Understood both by a programmer and computer.

• Common language used to wrote solutions.

Python Language — High level (closer to human level), general-purpose, interpreted (reads code line by line), dynamic (lines can be executed while program is running), programming language.

Programming Environment — The app wherein the program is made.

Variables — Containers

• Programmers get to name the variables

• Contents are changeable in later statements.

Rules in Naming a Variable:

Variables – Named containers

• Contain value of content to remember.
  

Post-Processing – State of an algorithm (happening in a certain point of the algorithm)

Data Types:

• String — Enclosed with two double quotes.

  • Integer- and float-applicable variables can also be enclosed in strings, so make sure to review the code carefully!

• Integer — Preferable for containers that use whole numbers.

• Float — Utilizes decimals for certain variables.

• Boolean (True or False).

Operators in Python (PEMDAS Structure):

• Addition: +

• Subtraction: - 

• Multiplication: *

• Division: /

• Integer/Floor Division: # or //

• Modulo (Remainder): %
  

Operator Precedence:

• Positive and negative (unary operators) always take the highest precedence.

• Divisions (/) will always result in a float data type.

• All other operations will result in a float if one of the integers is a float.

  • This specifically includes the floor division and modulo remainder.
