Operators

Python provides a wide range of operators that allow you to perform various operations on values and variables. Here are some of the most commonly used operators in Python:

1. Arithmetic Operators:

   • Addition: +

   • Subtraction: -

   • Multiplication: *

   • Division: /

   • Modulo (Remainder): %

   • Exponentiation: **

   • Floor Division: //

x = 10

y = 3

print(x + y)   # Output: 13

print(x - y)   # Output: 7

print(x * y)   # Output: 30

print(x / y)   # Output: 3.3333333333333335

print(x % y)   # Output: 1

print(x ** y)  # Output: 1000

print(x // y)  # Output: 3

2. Comparison Operators:

• Equal to: ==

• Not equal to: !=

• Greater than: >

• Less than: <

• Greater than or equal to: >=

• Less than or equal to: <=

x = 5

y = 3

print(x == y)  # Output: False

print(x != y)  # Output: True

print(x > y)   # Output: True

print(x < y)   # Output: False

print(x >= y)  # Output: True

print(x <= y)  # Output: False

3. Assignment Operators:

• Assignment: =

• Addition assignment: +=

• Subtraction assignment: -=

• Multiplication assignment: *=

• Division assignment: /=

• Modulo assignment: %=

• Exponentiation assignment: **=

• Floor division assignment: //=

x = 10

x += 5  # Equivalent to x = x + 5

print(x)  # Output: 15

x **= 2  # Equivalent to x = x ** 2

print(x)  # Output: 225

4. Logical Operators:

• Logical AND: and

• Logical OR: or

• Logical NOT: not

x = 5

y = 3

z = 7

print(x > y and x < z)  # Output: True

print(x > y or x > z)   # Output: True

print(not x > y)        # Output: False

5. Membership Operators:

• in: Evaluates if a value is present in a sequence.

• not in: Evaluates if a value is not present in a sequence.

fruits = ['apple', 'banana', 'orange']

print('banana' in fruits)       # Output: True

print('grape' not in fruits)    # Output: True

6. Identity Operators:

• is: Evaluates if two variables refer to the same object.

• is not: Evaluates if two variables do not refer to the same object.

x = [1, 2, 3]

y = [1, 2, 3]

z = x

print(x is y)       # Output: False

print(x is not y)   # Output: True

print(x is z)       # Output: True

These are just a few examples of the operators available in Python. Operators allow you to perform various computations and comparisons, and they play a crucial role in writing expressive and efficient code.
