    Study Notes

    Artificial Intelligence (AI)

    • AI was coined in 1956 by John McCarthy
    • AI is a technology that processes vast amounts of data from the internet to produce relevant results
    • Data is the fuel for AI
    • Sofia is an AI-based humanoid
    • Main AI Domains:
      • Data Science (analyzes data like CSV, used in games like rock-paper-scissors)
      • Computer Vision (analyzes images and videos, like in "Quick Draw")
      • Natural Language Processing (processes language, from speech to text and text to speech, analyzes sentence structure)

    Algorithms

    • An algorithm is a step-by-step procedure for solving a problem, expressed in a human-readable language.

    Flowcharts

    • A flowchart is a pictorial representation of an algorithm using standardized symbols.
    • Common flowchart symbols:
      • Oval: Start/Stop
      • Rectangle: Process/Calculations
      • Circle: Connector
      • Arrow: Flowlines
      • Parallelogram: Input/Output

    Python Programming Language

    • Python is a popular programming language for AI
    • Characteristics of Python:
      • Case-sensitive (upper/lowercase matters)
      • Open source (freely available)
      • Platform-independent (runs on many computing systems)
      • Large collection of libraries/functions
      • High-level programming language (easier to read and write)
      • Object-oriented programming approach
      • Easy to understand

    Python Variables

    • Rules for defining variables in Python:
      • Start with an alphabet or underscore
      • Single word, no spaces
      • No special characters, except underscore
      • Cannot be a reserved keyword
      • Maximum 256 characters

    Python Programming Modes

    • Interpreter mode: executes statements line by line
    • Script mode: executes a file containing a series of statements at once

    Python Tokens

    • Tokens are the smallest units of execution in Python
    • Types of tokens:
      • Literals (constants, like 4, 5.6, "Gauri" etc.)

    Python Operators

    • Operators perform specific actions on data
    • Types of operators:
      • Arithmetic
      • Logical
      • Comparison
      • Assignment
      • Unary
      • Delimiters (separators like []{}, #)
      • Escape characters (\t for tabs, \n for newlines)

    Python Data Types

    • int: Integer numbers (e.g., 45, -78)
    • float: Decimal numbers (e.g., 45.0, -2.8)
    • str: Text (e.g., 'hello', "world")
    • bool: Boolean values (True or False)
    • None: Represents a lack of value
    • list: Ordered collection of items (e.g., [1, "ram", "viii", "c"])

    Python Functions

    • Print(): Displays output to the console
    • Input(): Prompts the user to enter input
    • Type(): Determines the data type of a value
    • Int(): Converts a value to an integer
    • Float(): Converts a value to a floating-point number
    • Str(): Converts a value to a string

    Memory Units

    • Bits: 0 or 1 (the smallest unit)
    • Nibble: 4 bits
    • Byte: 8 bits = 1 character's worth of memory.
    • Kilobyte (KB): 1024 bytes
    • Megabyte (MB): 1024 KB
    • Gigabyte (GB): 1024 MB
    • Terabyte (TB): 1024 GB
    • print() displays output
    • Using parameters "sep" and "end" alters separation and ending characters when multiple items are provided as input
