 ## 📚 Variables
 
 Variables are containers for storing data values. In Python, you don't need to declare the type of a variable, as Python is dynamically typed. This means you can assign different types of values to the same variable.
 
-## 📜 String Variables
-
-- In this section, you'll learn about string variables in Python, including how to create them, perform operations like concatenation, slicing, and more.
+```python 
+a = 1
+b = True
+c = "Vibhav"
+d = None
+```
+- These are four variables of different data types.
+--- 
+## 📊 Data Type
+Data type specifies the type of value a variable holds. This is required in programming to do various operations without causing an error.
+In python, we can print the type of any operator using type function:
+```python
+a = 1
+print(type(a))
+b = "1"
+print(type(b))
+```
 
-### What is a String Variable?
+## 📜 String Datatype
 
-- A string variable is used to store text data. In Python, you can create a string variable by enclosing text in single quotes (`'`) or double quotes (`"`). Strings are immutable, meaning that once a string is created, it cannot be changed.
