    Study Notes

    User Input

    • Python allows users to provide input using the input() method.
    • When the program encounters input(), execution pauses until the user provides input.

    Python Operators

    • Operators are used to perform operations on variables and values.
    • Python classifies operators into groups:
      • Arithmetic Operators
      • Assignment Operators
      • Comparison Operators
      • Logical Operators
      • Identity Operators
      • Membership Operators
      • Bitwise Operators

    Arithmetic Operators

    • Used to perform common mathematical operations on numeric values.

    Addition

    • Adds two operands (+ symbol).

    Subtraction

    • Subtracts the second operand from the first (- symbol).

    Multiplication

    • Multiplies two operands (* symbol).

    Division

    • Divides the first operand by the second (/ symbol).

    Modulus

    • Returns the remainder of a division (% symbol).

    Exponentiation

    • Raises the first operand to the power of the second (** symbol).

    Floor Division

    • Performs division and returns the largest whole number less than or equal to the result (// symbol).

    Format Float

    • Limits the number of decimal places in a floating-point number.

    Assignment Operators

    • Used to assign values to variables.

    Assignment

    • Assigns a value to a variable (= symbol).

    Addition Assignment

    • Adds a value to an existing variable (+= symbol).

    Subtraction Assignment

    • Subtracts a value from an existing variable (-= symbol).

    Multiplication Assignment

    • Multiplies a value to an existing variable (*= symbol).

    Division Assignment

    • Divides an existing variable by a value (/= symbol).

    Modulus Assignment

    • Takes the modulus of an existing variable by a value (%= symbol).

    Exponentiation Assignment

    • Raises an existing variable to the power of a value (**= symbol).

    Floor Division Assignment

    • Performs floor division on an existing variable by a value (//= symbol).
