Python Operators and Arithmetic Operators

What are Operators in Python?

Operators are special symbols in Python that carry out arithmetic or logical computation. The value that the operator operates on is called the operand.

Example :
10 + 5 = 15.
Here, + is the operator that performs addition. 10 and 5 are the operands and 15 is the output of the operation.

Types of Operator

Python language supports the following types of operators.

  1. Arithmetic Operators
  2. Comparison (Relational) Operators
  3. Assignment Operators
  4. Logical Operators
  5. Bitwise Operators
  6. Membership Operators
  7. Identity Operators

Let us have a look on all operators one by one.

Arthimetic Operators

Arithmetic operators are used to perform mathematical operations like addition, subtraction, multiplication etc.

#Sample Code
a = 10
b = 20
print(a+b)
print('Sum of two numbers',a+b)
print('Sum of {1} + {1} + {1} ='.format(a,b),a+b)

Output:
30
Sum of two numbers 30
Sum of 20 + 20 + 20 = 30
# Sample Code 
x = 20
y = 5

# Addition Operator
print('Addition of {} + {} ='.format(x,y),x+y)

# Subtraction Operator
print('Subtraction of {} - {} ='.format(x,y),x-y)

# Multiplication Operator
print('Multiplication of {} * {} ='.format(x,y),x*y)

Output:
Addition of 20 + 5 = 25
Subtraction of 20 - 5 = 15
Multiplication of 20 * 5 = 100

Note: While multiplying Integer and Float value, the result will be a float value.

#Sample Code
j= 3 * 1.5
print(j)
print(type(j))

Output:
4.5
class 'float'
# Sample Code
x = 10
y = 3

# Float Division Operator
print('Float Division of {} / {} ='.format(x,y),x/y)

# Integer Division Operator
print('Integer Division of {} // {} ='.format(x,y),x//y)

# Integer Division for Negative Value
print('Integer Division of Negative Numbers =',-10//3)

Output:
Float Division of 10 / 3 = 3.3333333333333335
Integer Division of 10 // 3 = 3
Integer Division of Negative Numbers = -4
# Modulus or Remainder Operator
x = 5
y = 2
print('Modulus of {} % {} ='.format(x,y),x%y)

Output:
Modulus of 5 % 2 = 1
# Exponentiation Operator
x = 4
y = 2

print('Exponentiation of {} raise to the power {} ='.format(x,y),x**y)

Output:
Exponentiation of 4 raise to the power 2 = 16

Rule of Precedence in Python

Below table guides the order in which operation are carried out.

# Exponent followed by Subraction   
12 - 5 * 2

Output:
2
# Parenthesis followed by Multiplication 
(12 - 5) * 2

Output:
14
