Introduction: Python Arithmetic Operators

Arithmetic operators are used to perform mathematical operations in python. These are addition, subtraction, multiplication and division.

We’ll go through arithmetic operations one by one with proper practical code examples to better understand how they work. So let’s jump right into it.

7 Arithmetic Operators In Python (Explained With Examples)

These 7 Python arithmetic operators are listed below:

1. Addition
2. Subtraction
3. Multiplication
4. Division
5. Exponentiation
6. Modulus
7. Floor Division

Addition(+)

We can add values using this operator. See below example:

val1=20
val2=50
result=val1+val2
print(result)

Output

70

This operator can also be used to concatenate Python strings. See below example:

v1='This is '
v2='Python'
res=v1+v2
print(res)

Output

This is Python

We can also add integer with float value. See below example:

v1=20
v2=40.5
res=v1+v2
print(res)

Output

60.5

See also below example in which three values are added.

v1=20.0
v2=40.5
v3=637
res=v1 + v2 + v3
print(res)

Output

697.5

Subtraction(-)

This operator is used to subtract values. See below examples:

val1=20.0
val2=40.5
result=val1 - val2
print(result)
print(20 - 56 - 10)
print(15.3 - 56.0 - 20)
print(52 - 10 - 20)

Output

-20.5 
-46 
-60.7 
22

We can see through the above examples that if a higher value operand has the subtraction operator on its left side, then it’ll also be shown in the result.

Multiplication(*)

As the name suggests, this Python operator is used to multiply the values of its operands. See below examples:

a=5
b=3
result=a * b
print(result)
print(20 * 10)
print(5 * 3.9)
print(10 * 23 * 5.0)

Output

15 
200 
19.5 
1150.0

Division(/)

This operator is used to perform the division operation. See below examples:

a=10
b=4
result=a / b
print(result)
print(4 / 3)
print(10 / 18)
print(40 / 34.2)
print(5 / 10.2 / 55)

Output

2.5 
1.3333333333333333 
0.5555555555555556 
1.1695906432748537 
0.008912655971479501

Exponentiation(**)

This operator is used to specify second operand as a power to the first operand. See below examples:

a=10
b=5
res=a**b
print(res)
print(2**3)
print(4**2**3)
print(5**4.3)
print(4**3**2.8)

Output

100000 
8 
65536 
1012.9103729329762 
11195966703675.746

Modulus(%)

This operator is used to fetch the remainder of values passed to it as an operands. It first divide them and then return/show its remainder. See below examples:

aa=14
bb=5
res=aa % bb
print(res)
print(30 % 14)
print(10 % 3)
print(15 % 4.6)
print(54 % 10.8 % 5)

Output

4 
2 
1 
1.200000000000001 
0.7999999999999972

Floor Division(//)

This operator is used to find floor of quotient after division takes place. See below examples:

a=4
b=3
print(a/b)   // simple division
print(a//b)  // floor division

Output

1.3333333333333333   // simple division
1                    // floor division

Other examples are given below:

print(4//5)
print(40//34)
print(10//3.5)
print(20//5.3//4)
print(23//5//4)

Output

0 
1 
2.0 
0.0 
1

So this is how we can use Python arithmetic operators.

Python Program Implementing All 7 Operators

This program will implement all 7 Python arithmetic operators. It’s a simple program which will first ask the user to enter a specific symbol to select the type of operation. After that, it’ll ask the user to enter two numbers(in integer format). At last, it’ll show the result. See below code:

class AOClass:
  def arOperations(self,symbol,val1,val2):
    if symbol=='+':
      return val1+val2
    elif symbol=='-':
      return val1-val2
    elif symbol=='*':
      return val1*val2
    elif symbol=='/':
      return val1/val2
    elif symbol=='-':
      return val1-val2
    elif symbol=='%':
      return val1-val2
    elif symbol=='**':
      return val1**val2
    elif symbol=='//':
      return val1//val2
    else:
      return 'wrong input'


sym=input('''
Choose the type of operation(Enter the symbol):
Addition(+)
Subtraction(-)
Multiplication(*)
Division(/)
Exponentiation(**)
Modulus(%)
Floor Division(//)
''')

a=int(input('Enter first value(only in integer format):'))
b=int(input('Enter second value(only in integer forma):'))

obj=AOClass()
result=obj.arOperations(sym,a,b)
print(result)

Output

Choose the type of operation(Enter the symbol): 
Addition(+) 
Subtraction(-) 
Multiplication(*) 
Division(/) 
Exponentiation(**) 
Modulus(%) 
Floor Division(//)

**          # entered symbol

Enter first value(only in integer format):
2

Enter second value(only in integer forma):
6

64          # result
