    Study Notes

    Basic Syntax

    • Indentation: uses spaces (not tabs) to define block-level structure
    • Comments: start with # and extend to the end of the line
    • Print function: print() is used to output text to the screen

    Data Types

    • Integers: whole numbers, e.g. 1, 2, 3, etc.
    • Floats: decimal numbers, e.g. 3.14, -0.5, etc.
    • Strings: sequences of characters, e.g. "hello", 'hello', etc.
      • String concatenation: + operator, e.g. "hello " + "world"
      • String formatting: % operator, e.g. "hello %s" % "world"
    • Boolean: true or false values
    • Lists: ordered collections of items, e.g. [1, 2, 3], ["a", "b", "c"]
      • Indexing: access individual elements with [], e.g. my_list[0]
      • Slicing: access a subset of elements with [], e.g. my_list[1:3]

    Control Structures

    • If-else statements: conditional execution of code
      • Syntax: if condition : code elif condition : code else: code
    • For loops: iterate over a sequence
      • Syntax: for variable in sequence : code
    • While loops: repeat code while a condition is true
      • Syntax: while condition : code

    Functions

    • Defining functions: create reusable code blocks
      • Syntax: def function_name (parameters): code
    • Function calls: execute a function with arguments
      • Syntax: function_name(arguments)

    Modules

    • Importing modules: load external libraries
      • Syntax: import module_name
    • Module functions: access functions from a module
      • Syntax: module_name.function_name(arguments)
