2. Running Python

• python is both a compiler (to bytecode) and interpreter

3. Python Basics

• floats are objects; shouldn't be compared, but they're faster and smaller than decimal
  • have as_integer_ratio method
• format() function allows you to specify decimal points
• abs() is absolute value
• entities have state (data) and methods (functionality)
  • "The method operates the data in the class, while a function is used to return or pass the data. A function can be directly called by its name, while a method can't be called by its name."
• immutable objects: integers, decimals, floats
• variables
  • must start with underscore or letter
  • standard use snake case and lowercase
