Data types


Data type informs to the PVM (Python Virtual Machine) what type of data present inside a variable (object reference).
In python, we are not required to specify the data type. Based on the data, the data type will be assigned automatically hence Python is Dynamically Typed Language.
In c /java language we should write data types explicitly.

Remember one thing in Python, everything is treated as object. You will be known in future sessions what is object.

Ex: C language example program how we use data types for variable initialization
#include<stdio.h>
void main()
{
  int a=5; 
  float b=2.4;
  char *=”Python\0”;
}

Example program in Python:

>>> a=5 # Here 5 integer value.
>>> print(type(a)) # type() is used to find the data type of object
Result is:
<class 'int'>
>>> print(id(a)) # id() function is used to find the address of the object
Result is:
1526782192
>>> print(a) # value of the object
Result is:

5

Types of Data types:
1. Built-in Data types (Basic Data types)
2. Derived Data types
3. User-defined data types
