Basic Operators

Operators are symbols that perform specific operations on one or more values. Python supports several types of operators:

Arithmetic Operators

Used for basic mathematical operations:

• +: Addition
• -: Subtraction
• *: Multiplication
• /: Division
• %: Modulus (remainder)
• //: Floor division (integer division)
• ****: Exponentiation

Python

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: 3
print(x ** y)  # Output: 1000

Comparison Operators

Used to compare values:

• ==: Equal to
• !=: Not equal to
• <: Less than
• >: Greater than
• <=: Less than or equal to
• >=: Greater than or equal to

Python

x = 10
y = 5
print(x == y)  # Output: False
print(x != y)  # Output: True
print(x > y)  # Output: True

Logical Operators

Used to combine conditional statements:

• and: Both conditions must be true
• or: At least one condition must be true
• not: Negates a condition

Python

x = True
y = False
print(x and y)  # Output: False
print(x or y)  # Output: True
print(not x)  # Output: False

Assignment Operators

Used to assign values to variables:

• =: Simple assignment
• +=: Add and assign
• -=: Subtract and assign
• *=: Multiply and assign
• /=: Divide and assign
• %=: Modulus and assign
• //=: Floor division and assign
• ****: Exponentiation and assign

Python

x = 5
x += 3  # Equivalent to x = x + 3
print(x)  # Output: 8

Other Operators

• Identity operators: is and is not (compare object identities)
• Membership operators: in and not in (check for membership in sequences)
