Python Operators

Operators are special symbols that perform operations on variables and values. Python has various types of operators, including arithmetic, comparison, logical, assignment, bitwise, and membership operators.

Arithmetic Operators

Arithmetic operators are used to perform mathematical operations.

• Addition (+):

  result = 5 + 3  # Output: 8

  result = 5 + 3  # Output: 8

Adds two values.

• Subtraction (-):

  result = 10 - 6  # Output: 4

  result = 10 - 6  # Output: 4

Subtracts the second value from the first.

• Multiplication (*):

  result = 4 * 7  # Output: 28

  result = 4 * 7  # Output: 28

Multiplies two values.

• Division (/):

  result = 16 / 4  # Output: 4.0

  result = 16 / 4  # Output: 4.0

Divides the first value by the second.

• Floor Division (//):

  result = 17 // 3  # Output: 5

  result = 17 // 3  # Output: 5

Divides the first value by the second and returns the largest integer less than or equal to the result.

• Modulus (%):

  result = 10 % 3  # Output: 1

  result = 10 % 3  # Output: 1

Returns the remainder of the division.

• Exponentiation ()**:

  result = 2 ** 3  # Output: 8

  result = 2 ** 3  # Output: 8

Raises the first value to the power of the second.

Comparison Operators

Comparison operators compare two values and return True or False.

• Equal to (==):

  result = (5 == 5)  # Output: True

  result = (5 == 5)  # Output: True

Checks if two values are equal.

• Not equal to (!=):

  result = (5 != 3)  # Output: True

  result = (5 != 3)  # Output: True

Checks if two values are not equal.

• Greater than (>):

  result = (7 > 3)  # Output: True

  result = (7 > 3)  # Output: True

Checks if the first value is greater than the second.

• Less than (<):

  result = (4 < 9)  # Output: True

  result = (4 < 9)  # Output: True

Checks if the first value is less than the second.

• Greater than or equal to (>=):

  result = (6 >= 6)  # Output: True

  result = (6 >= 6)  # Output: True

Checks if the first value is greater than or equal to the second.

• Less than or equal to (<=):

  result = (8 <= 10)  # Output: True

  result = (8 <= 10)  # Output: True

Checks if the first value is less than or equal to the second.

Logical Operators

Logical operators are used to combine conditional statements.

• and:

  result = (5 > 3) and (8 > 5)  # Output: True

  result = (5 > 3) and (8 > 5)  # Output: True

Returns True if both conditions are true.

• or:

  result = (5 > 3) or (8 < 5)  # Output: True

  result = (5 > 3) or (8 < 5)  # Output: True

Returns True if at least one condition is true.

• not:

  result = not (5 > 3)  # Output: False

  result = not (5 > 3)  # Output: False

Reverses the result of the condition.

Assignment Operators

Assignment operators are used to assign values to variables.

• Assign (=):

  x = 5

  x = 5

Assigns the value 5 to x.

• Add and assign (+=):

  x = 5
  x += 3  # Equivalent to x = x + 3

  x = 5

  x += 3  # Equivalent to x = x + 3

Adds the right operand to the left operand and assigns the result to the left operand.

• Subtract and assign (-=):

  x = 5
  x -= 2  # Equivalent to x = x - 2

  x = 5

  x -= 2  # Equivalent to x = x - 2

Subtracts the right operand from the left operand and assigns the result to the left operand.

• Multiply and assign (*=):

  x = 5
  x *= 4  # Equivalent to x = x * 4

  x = 5

  x *= 4  # Equivalent to x = x * 4

Multiplies the left operand by the right operand and assigns the result to the left operand.

• Divide and assign (/=):

  x = 10
  x /= 2  # Equivalent to x = x / 2

  x = 10

  x /= 2  # Equivalent to x = x / 2

Divides the left operand by the right operand and assigns the result to the left operand.

• Modulus and assign (%=):

  x = 10
  x %= 3  # Equivalent to x = x % 3

  x = 10

  x %= 3  # Equivalent to x = x % 3

Takes the modulus using two operands and assigns the result to the left operand.

• Exponentiation and assign (=)**:

  x = 2
  x **= 3  # Equivalent to x = x ** 3

  x = 2

  x **= 3  # Equivalent to x = x ** 3

Raises the left operand to the power of the right operand and assigns the result to the left operand.
