1. Data Types

Key Concepts & Definitions

  • Data Types: Categories of data that determine what kind of value a variable can hold (e.g., int, float, str, bool).
  • Variables: Named storage locations in memory that hold data values, which can be of different data types.
  • Type Casting: Converting a value from one data type to another (e.g., int to float).
  • Operators: Symbols that perform operations on variables and values (e.g., +, -, *, /).
  • Arithmetic Expressions: Combinations of variables, values, and operators that evaluate to a single value.
  • Escape Sequences: Special characters used in strings to represent characters that are difficult to include directly (e.g., \n for newline, \t for tab).
