What are Operators in Python?

Types of Python Operators

• Arithmetic Operators
• Comparison (Relational) Operators
• Assignment Operators
• Logical Operators
• Bitwise Operators
• Membership Operators
• Identity Operators

Python Arithmetic Operators

a = 21
b = 10
# Addition
print ("a + b : ", a + b)
# Subtraction
print ("a - b : ", a - b)
# Multiplication
print ("a * b : ", a * b)
# Division
print ("a / b : ", a / b)
# Modulus
print ("a % b : ", a % b)
# Exponent
print ("a ** b : ", a ** b)
# Floor Division
print ("a // b : ", a // b)

Output

a + b : 31
a - b : 11
a * b : 210
a / b : 2.1
a % b : 1
a ** b : 16679880978201
a // b : 2

Python Comparison Operators

Example

a = 4
b = 5
# Equal
print ("a == b : ", a == b)
# Not Equal
print ("a != b : ", a != b)
# Greater Than
print ("a > b : ", a > b)
# Less Than
print ("a < b : ", a < b)
# Greater Than or Equal to
print ("a >= b : ", a >= b)
# Less Than or Equal to
print ("a <= b : ", a <= b)

This code compares the values of variables 'a' and 'b' and prints if they are equal, not equal, greater than, less than, more than or equal to, and less than or equal to each other.

Output

a == b : False
a != b : True
a > b : False
a < b : True
a >= b : False
a <= b : True

Python Assignment Operators

Assignment Operator in Python is a key element in Python programming. The assignment operator in Python allows the programmer to create, manipulate, and assign values to any Python variable in an efficient manner. Python Assignment Operators can be used in a variety of ways: they can perform basic math operations; they can assign multiple objects with one statement; they can assign unchanged input variables to different output locations; and many more ways.

Example

# Assignment Operator
a = 10
# Addition Assignment
a += 5
print ("a += 5 : ", a)
# Subtraction Assignment
a -= 5
print ("a -= 5 : ", a)
# Multiplication Assignment
a *= 5
print ("a *= 5 : ", a)
# Division Assignment
a /= 5
print ("a /= 5 : ",a)
# Remainder Assignment
a %= 3
print ("a %= 3 : ", a)
# Exponent Assignment
a **= 2
print ("a **= 2 : ", a)
# Floor Division Assignment
a //= 3
print ("a //= 3 : ", a)

The Python assignment operators are shown in this code. It begins with the value of 'a' equal to 10, and then goes through the steps of addition, subtraction, multiplication, division, remainder, exponentiation, and floor division, updating 'a' as necessary and outputting the results.

Output

a += 5 : 105
a -= 5 : 100
a *= 5 : 500
a /= 5 : 100.0
a %= 3 : 1.0
a **= 2 : 1.0
a //= 3 : 0.0

Python Bitwise Operators

Example

a = 60 # 60 = 0011 1100
b = 13 # 13 = 0000 1101
# Binary AND
c = a & b # 12 = 0000 1100
print ("a & b : ", c)
# Binary OR
c = a | b # 61 = 0011 1101
print ("a | b : ", c)
# Binary XOR
c = a ^ b # 49 = 0011 0001
print ("a ^ b : ", c)
# Binary Ones Complement
c = ~a; # -61 = 1100 0011
print ("~a : ", c)
# Binary Left Shift
c = a << 2; # 240 = 1111 0000
print ("a << 2 : ", c)
# Binary Right Shift
c = a >> 2; # 15 = 0000 1111
print ("a >> 2 : ", c)

The binary representations of the numbers 'a' and 'b' are subjected to bitwise operations in this code. It displays the results of binary AND, OR, XOR, Ones Complement, Left Shift, and Right Shift operations.

Output

a & b : 12
a | b : 61
a ^ b : 49
~a : -61
a >> 2 : 240
a >> 2 : 15

Python Logical Operators

Example

a = 20
b = 20
c = -10
if a > 0 and b > 0:
 print("The numbers are greater than 0")
if a > 0 and b > 0 and c > 0:
 print("The numbers are greater than 0")
else:
 print("Atleast one number is not greater than 0")

The code prints "The numbers are greater than 0" if variables "a" and "b" are greater than 0 in the test. Then it checks to see if all three variables ('a,' 'b,' and 'c') are greater than 0, but since 'c' is not, it outputs "At least one number is not greater than 0."

Output

The numbers are greater than 0
Atleast one number is not greater than 0

Python Membership Operators

Example

a = 10
b = 20
list = [1, 2, 3, 4, 5 ];
if ( a in list ):
   print "Line 1 - a is available in the given list"
else:
   print "Line 1 - a is not available in the given list"
if ( b not in list ):
   print "Line 2 - b is not available in the given list"
else:
   print "Line 2 - b is available in the given list"
a = 2
if ( a in list ):
   print "Line 3 - a is available in the given list"
else:
   print "Line 3 - a is not available in the given list"

The 'in' and 'not in' operators are used in this code to show how to verify whether the values 'a' and 'b' are present in the list. When 'a' is set to 2, it checks once more to make sure that 'a' is present in the list and outputs if each value is present or not.

Output

Line 1 - a is not available in the given list
Line 2 - b is not available in the given list
Line 3 - a is available in the given list

Python Identity Operators

Example

a = 20
b = 20
if ( a is b ):
   print "Line 1 - a and b have same identity"
else:
   print "Line 1 - a and b do not have same identity"
if ( id(a) == id(b) ):
   print "Line 2 - a and b have same identity"
else:
   print "Line 2 - a and b do not have same identity"
b = 30
if ( a is b ):
   print "Line 3 - a and b have same identity"
else:
   print "Line 3 - a and b do not have same identity"
if ( a is not b ):
   print "Line 4 - a and b do not have same identity"
else:
   print "Line 4 - a and b have same identity"

The 'is' and 'is not' operators are used in this code to show how to verify the identity (memory address) of the variables 'a' and 'b'. It indicates whether or not 'a' and 'b' share the same identity, and it updates 'b' to 30 to show that they no longer share the same identity under the third and fourth requirements.

Output

Line 1 - a and b have same identity
Line 2 - a and b have same identity
Line 3 - a and b do not have same identity
Line 4 - a and b do not have same identity
