    Study Notes

    Python Programming Concepts

    • An ordered set of instructions for a computer is called an algorithm, pseudocode, or program.
    • A computer understands machine language (binary code).
    • Python uses an interpreter to convert high-level code to machine language.
    • Python is an open-source language developed by Guido Van Rossum.

    Python Data Types and Variables

    • Python is case sensitive.
    • Keywords in Python are lowercase.
    • To run Python programs, use Ctrl+R or F6/F5.
    • Identifiers are used to name variables, functions, etc. They cannot start with numbers and must not be keywords.
    • Identifiers cannot include special symbols.

    Python Comments and Statements

    • Comments are used to explain code (e.g., # this is a comment).
    • Single-line comments start with #.
    • Multi-line comments use triple quotes ("""Docstring""").
    • Python code can use interactive or script mode.
    • By default, Python files have a .py extension.
    • Python files are saved in the Python installation folder or the user's desktop.

    Python Data Structures and Operations

    • Python supports various data types, including integers, floats, strings, booleans.
    • Variables hold data values.
    • Data types like integers, floats, and other types, can hold single values.
    • An operand in math or logic is a value subjected to an operation.
    • An operator is a symbol used in mathematical or logical operations.

    Python Operators and Keywords

    • Keywords are reserved words in Python.
    • Operators perform operations on values.
    • An identifier is a name given to a variable in a program.
    • Literals represent fixed-value data items, like numbers or strings.
    • Python has different data types such as integers, floats, strings, lists, tuples, and dictionaries.

    Python Input and Output

    • The input() function in Python takes input from the user.
    • The input can be a number or a string.

    Python Features and Properties

    • Python's case sensitivity is crucial when working with variables and keywords.
    • Key features include being an open-source language; not case-sensitive codeblocks using brackets; Python is not proprietary software.
