Python Operators With Examples

Python operators allow us to do common processing on variables. We will look into different types of python operators with examples and also operator precedence.

Python Operators

Python Operators are the special symbols that can manipulate values of one or more operands.

Python Operator Types

Python operators can be classified into several categories.

Arithmetic Operators
Logical Operators
Comparison Operators
Bitwise Operators
Assignment Operators

Python Arithmetic Operators

Operator	Description	Example
+	used to add two numbers	sum = a + b
–	used for subtraction	difference = a – b
*	used to multiply two numbers. If a string and int is multiplied then the string is repeated the int times.	mul = ab >>> “Hi”5 ‘HiHiHiHiHi’
/	used to divide two numbers	div = b/a
%	modulus operator, returns the remainder of division	mod = a%b
**	exponent operator


#create two variables
a=100
b=200
# addition (+) operator
print(a+b)
# subtraction (-) operator
print(a-b)
# multiplication (*) operator
print(a*b)
# division (/) operator
print(b/a)
# modulus (%) operator
print(a%b) # prints the remainder of a/b
# exponent (**) operator
print(a**b) #prints a^b

#create two variables

a=100

b=200

# addition (+) operator

print(a+b)

# subtraction (-) operator

print(a-b)

# multiplication (*) operator

print(a*b)

# division (/) operator

print(b/a)

# modulus (%) operator

print(a%b) # prints the remainder of a/b

# exponent (**) operator

print(a**b) #prints a^b

Python Comparison Operators

Operator	Description	Example
==	returns True if two operands are equal, otherwise False.	flag = a == b
!=	returns True if two operands are not equal, otherwise False.	flag = a != b

<	returns True if left operand is smaller than the right operand, otherwise False.	flag = a < b
>=	returns True if left operand is greater than or equal to the right operand, otherwise False.	flag = a > b
<=	returns True if left operand is smaller than or equal to the right operand, otherwise False.	flag = a < b


# create two variables
a=100
b=200
# (==) operator, checks if two operands are equal or not
print(a==b)
# (!=) operator, checks if two operands are not equal
print(a!=b)
# (&gt;) operator, checks left operand is greater than right operand or not
print(a&gt;b)
# (&lt;) operator, checks left operand is less than right operand or not
print(a&lt;b)
#(&gt;=) operator, checks left operand is greater than or equal to right operand or not
print(a&gt;=b)
# (&lt;=) operator, checks left operand is less than or equal to right operand or not
print(a&lt;=b)

# take two variable, assign values with assignment operators

# it is equivalent to a=a+b
a+=b
print("a: "+str(a))

# take two variable, assign values with assignment operators

a=3

print("a: "+str(a))

print("b: "+str(b))

# it is equivalent to a=a+b

a+=b

print("a: "+str(a))

print("b: "+str(b))

# it is equivalent to a=a*b

a*=b

print("a: "+str(a))

print("b: "+str(b))

# it is equivalent to a=a/b

a/=b

print("a: "+str(a))

print("b: "+str(b))

a%=b

print("a: "+str(a))

print("b: "+str(b))

# it is equivalent to a=a**b ( exponent operator)

a**=b

print("b: "+str(b))

a//=b

print("b: "+str(b))

Python Assignment Operators

Python Operator Precedence

Precedence of python operators means the priority level of operators. This becomes vital when an expression has multiple operators in it. For example consider the following expression:


&gt;&gt;&gt; 2+3*4

>>> 2+3*4

Now, what do you think the series of operation would be? We can add 2 and 3, then multiply the result by 4. Also, we can multiply 3 and 4 first, then add 2 with it. Here we can see that the operators’ precedence is important.

Below is a list of operators indicating the precedence level. It’s in descending order. That means the upper group has more precedence than that of the lower group.

Parenthesis – ()
Exponentiation – **
Compliment, unary plus and minus – ~, +, -
Multiply, Divide, modulo – *, /, %
Addition and Subtraction – +, -
Right and Left Shift – >>, <<
Bitwise AND – &
Bitwise OR and XOR – |, ^
Comparison Operators – ==, !=, >, <, >=, <=
Assignment Operator- =
