\ud83c\udfaf Lesson Objective<\/strong><\/h3>\n\n\n\n

To understand different types of operators<\/strong> in Python and how to use them in expressions<\/strong> to perform calculations or logic.<\/p>\n\n\n\n

\n\n\n\n

\ud83e\udde0 1. What Are Operators?<\/strong><\/h3>\n\n\n\n

Operators are special symbols that perform operations on variables and values.
Expressions<\/strong> are combinations of variables, operators, and values that produce a result.<\/p>\n\n\n\n

Example:<\/p>\n\n\n\n

x = 10\ny = 5\nresult = x + y\nprint(result)  # Output: 15\n<\/code><\/pre>\n\n\n\n
\n\n\n\n
\u2699\ufe0f 2. Types of Operators<\/strong><\/h3>\n\n\n\n
A. Arithmetic Operators<\/strong><\/h4>\n\n\n\n

Example:<\/p>\n\n\n\n
a, b = 10, 3\nprint(a + b, a - b, a * b, a \/ b, a \/\/ b, a % b, a ** b)\n<\/code><\/pre>\n\n\n\n
\n\n\n\n
B. Comparison Operators<\/strong><\/h4>\n\n\n\n
Used to compare two values. They return either True<\/strong> or False<\/strong>.<\/p>\n\n\n\n
Operator<\/th>Meaning<\/th>Example<\/th>Output<\/th><\/tr><\/thead>
==<\/code><\/td>Equal to<\/td>5 == 5<\/code><\/td>True<\/td><\/tr>
!=<\/code><\/td>Not equal to<\/td>5 != 3<\/code><\/td>True<\/td><\/tr>
><\/code><\/td>Greater than<\/td>7 > 4<\/code><\/td>True<\/td><\/tr>
<<\/code><\/td>Less than<\/td>3 < 5<\/code><\/td>True<\/td><\/tr>
>=<\/code><\/td>Greater or equal<\/td>5 >= 5<\/code><\/td>True<\/td><\/tr>
<=<\/code><\/td>Less or equal<\/td>4 <= 3<\/code><\/td>False<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
Example:<\/p>\n\n\n\n
x, y = 10, 20\nprint(x > y)  # False\nprint(x != y) # True\n<\/code><\/pre>\n\n\n\n
\n\n\n\n
C. Logical Operators<\/strong><\/h4>\n\n\n\n
Used to combine conditional statements.<\/p>\n\n\n\n
Operator<\/th>Description<\/th>Example<\/th>Output<\/th><\/tr><\/thead>
and<\/code><\/td>True if both are true<\/td>x > 5 and y < 30<\/code><\/td>True<\/td><\/tr>
or<\/code><\/td>True if one is true<\/td>x > 15 or y < 30<\/code><\/td>True<\/td><\/tr>
not<\/code><\/td>Reverses the result<\/td>not(x > 5)<\/code><\/td>False<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
Example:<\/p>\n\n\n\n
x, y = 10, 20\nprint(x > 5 and y < 25)  # True\nprint(x > 15 or y < 25)  # True\nprint(not(x > 5))        # False\n<\/code><\/pre>\n\n\n\n
\n\n\n\n
D. Assignment Operators<\/strong><\/h4>\n\n\n\n
Used to assign values to variables.<\/p>\n\n\n\n
Operator<\/th>Example<\/th>Equivalent To<\/th><\/tr><\/thead>
=<\/code><\/td>x = 10<\/code><\/td>x = 10<\/code><\/td><\/tr>
+=<\/code><\/td>x += 2<\/code><\/td>x = x + 2<\/code><\/td><\/tr>
-=<\/code><\/td>x -= 3<\/code><\/td>x = x - 3<\/code><\/td><\/tr>
*=<\/code><\/td>x *= 2<\/code><\/td>x = x * 2<\/code><\/td><\/tr>
\/=<\/code><\/td>x \/= 2<\/code><\/td>x = x \/ 2<\/code><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

a, b = 5, 3\nprint(a & b, a | b, a ^ b)\n<\/code><\/pre>\n\n\n\n
\n\n\n\n
\ud83e\udde9 3. Expressions<\/strong><\/h3>\n\n\n\n
An expression<\/strong> is a combination of values, variables, and operators that evaluates to a result.<\/p>\n\n\n\n
Example:<\/p>\n\n\n\n
x = 10\ny = 5\nz = (x + y) * 2\nprint(z)  # Output: 30\n<\/code><\/pre>\n\n\n\n
\n\n\n\n
\ud83e\udde0 4. Practice Ideas<\/strong><\/h3>\n\n\n\n
    \n
  1. Write a Python program to calculate the area of a rectangle using variables.<\/li>\n\n\n\n
  2. Check if a number is positive and even using comparison and logical operators.<\/li>\n\n\n\n
  3. Create a program that swaps two variables using assignment operators.<\/li>\n<\/ol>\n\n\n\n
