7 Python Operators with examples
In C, C++ languages like python also have 7 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
1. Arithmetic Operators :
Arithmetic Operators are like addition, subtraction, division, multiplication, Modular, and Floor Division.
Example:
a= 5
b= 4
print('a+b =', a+b)
print('a-b =', a-b)
print('a*b =', a*b)
print('a/b =', a/b)
print('a%b =', a%b)
print('a//b =', a//b)
Output:
a+b = 9 a-b = 1 a*b = 20 a/b = 1.25 a%b = 1 a//b = 1
2. Comparison Operations:
Comparison Operators compare both sides of the values. It will produce true and false results. The operators ==,!=, >, <, <>, <=,>=.
Example:
a= 5
b= 4
print('a==b =', a==b)
print('a!=b =', a!=b)
print('a>b =', a>b)
print('a<b =', a<b)
print('a>=b =', a>=b)
print('a<=b =', a<=b)
Output:
a==b = False a!=b = True a>b = True a<b = False a>=b = True a<=b = False
3. Assignment Operators:
These operators are used to assign values to variables. You can do arithmetic operations while assigning variables also.
Example:
a= 5
b= 4
c=0
print('C value', c)
c+=a
print('C value', c)
c*=a
print('C value', c)
c-=a
print('C value', c)
c/=a
print('C value', c)
c%=a
print('C value', c)
c//=a
print('C value', c)
c**=a
print('C value', c)
Output:
C value 0 C value 5 C value 25 C value 20 C value 4.0 C value 4.0 C value 0.0 C value 0.0
Python Logical Operators:
In python we have 3 logical operators are there. And, Or, Not – We can use these operators with multiple statement comparisons
And – If both the statements true it returns, true value
Or – if any one of the statement false it returns true value
Not – It is used to reverse the result with true to false or false to true
Example:
a= 5
b= 4
c=7
print('a>b and c>b =', a>b and c>b)
print('a>b or c>b =', a>b or c>b)
print('not(a>b or c>b) =', not(a>b and c>b))
Output:
a>b and c>b = True a>b or c>b = True not(a>b or c>b) = False
Python Identity Operators:
We have 2 identity operators in python. We can use them to compare variable values. If the value of variable is equal it returns true value, otherwise it returns false value.
Is – Returns true value if the both variables have same object
Is not – Returns true value if the both variables have not same object
Example 1:
a= 5
b= 4
print('a is b', a is b)
print('a is not b =', a is not b)
Output:
a is b False a is not b = True
Example 2:
a= 5
b= 5
print('a is b', a is b)
print('a is not b =', a is not b)
Output:
a is b True a is not b = False
Python Membership operators:
Python membership operators are used to test the variables are present in the sequences of tuples, lists, arrays and strings. We have 2 membership operators.
In – Returns true value, if the object present in sequence
Not in – Returns true value, if the object not present in sequence
Example 1:
a= 3
b= [2,3,5,8,9]
print('a in b', a in b)
print('a not in b =', a not in b)
Output:
a in b True a not in b = False
Example 2:
a= 4
b= [2,3,5,8,9]
print('a in b', a in b)
print('a not in b =', a not in b)
Output:
a in b False a not in b = True
Python Bitwise Operators:
In python we have 6 bitwise operators – &, |, ^, ~, >>, <<. It performed operation bit by bit between variables.
Example:
a= 5
b= 5
print('a & b =', a & b)
print('a | b =', a | b)
print('a ^ b =', a ^ b)
print('a ~ b =', a ~ b)
print('a<<b =', a<<b)
print('a>>b =', a>>b)
Output:
a & b = 5 a | b = 5 a ^ b = 0 a ~ b = -6 a<<b = 160 a>>b = 0
