Python is a dynamically typed programming language which means there is no need to declare the data type of variable.

Example

x=12
    y="hello world"
    z=15.45
    print(x)
    print(y)
    print(z)
    
    #PTHON OUTPUT
    12
    hello world
    15.45

To check variable belongs to which data type use type()  built-in method in python.

Example

x = 15 #<class 'int'> interger
    y = "Hello Python" #<class 'str'> string
    z = 21.20 #<class 'float'> float
    a = True #<class 'bool'> boolean
    
    #print all Variables
    print(x, y, z, a)
    
    #print datatype of Variables
    print(type(x), type(y), type(z), type(a))
    
    #python output
    <class 'int'> <class 'str'> <class 'float'> <class 'bool'>

Combine Variables

In python, operators are used to combining, do mathematical calculation or logical conditioning.

Example

a = 10
    b = 5
    c = 10+5
    
    print(c)
    
    #python output
    15
