#logical operator and, or, not.

type() Function

type() function is use for find data type for variable.

a= 50

b= "PIrates"

c= 30.5

print(type(a))

print(type(b))

print(type(c))

Output

<class 'int'>

<class 'str'>

<class 'float'>

Type Casting

numeric variable is converteble like 

a= 50

b= "50"

c= 50.0

print(type(a))

print(type(b))

print(type(c))

Output

<class 'str'>
