Python Operators


Python Tutorial for Beginners
Python Operators

Operators are used to perform Arithmetic, Comparison, and Logical Operations...

Important categories of operators in Python:

1) Arithmetic Operators
2) Comparison (Relational) Operators
3) Assignment Operators
4) Logical Operators
5) Identity Operators
6) Bitwise Operators
--------------------------------
1) Python Arithmetic Operators

i) + Addition (Example: 10 + 20) = 30
ii) - Subtraction (Example: 10 - 20) = -10
iii) * Multiplication (Example: 10 * 20) = 200
iv) / Division (Example: 20/10) = 2
v) % Modulus (Example: 20 % 10) = 0
vi) ** Exponent (Example: 10 ** 20) = 
--------------------------------
Examples:

a=10;
b=20;
c=3;

print (a+b);
print (a-b);
print (a*b);
print (a/c);
print (b%a);
print (a**c);
print (a//c);

Output:
30
-10
200
3.3333333333333335
0
1000
3
--------------------------------
2) Python Comparison (Relational) Operators

i) ==
ii) !=
iii) >
iv) <
v) >=
vi) <=
-------------------
Examples:
a=10;
b=20;

print (a == b);
print (a != b);
print (a > b);
print (a < b);
print (a >= b);
print (a <= b);

Output:
False
True
False
True
False
True
--------------------------------
3) Python Assignment Operators

i) = Equal to
ii) += Add And 
iii) -= Subtract And
iv) *= Multiply And
v) /= Divide And
vi) %= Modula And
vii) **= Exponent And
viii) //= Floor Division And

Examples:

a=10;
b=3;
print (a);
print (b);

a += b;
print (a);

a -=b;
print (a);

a *=b;
print (a);

a /=b;
print (a);

a **=b;
print (a);

a //=b;
print (a);

Output:
10
3
13
10
30
10.0
1000.0
333.0
--------------------------------
4) Python Logical Operators

i) and (Loical And)
ii) or (Loical Or)
iii) Not (Loical Not)

Examples:
x='true';
y='false';

print (x and y); # false

print (x or y); # true

print (not x); # false
--------------------------------
5) Python Identity Operators

i) is
ii) is not

Examples:

x1 = 5;
y1 = 5;

print (x1 is not y1); # false

print (x1 is y1); # true
