Variables
• Variables are containers for storing data values.
• Python has no command for declaring a variable.
• A variable is created the moment you first assign a value to it.
• Variables do not need to be declared with any particular type, and can even change type after they have been set.
Variable Names
A variable can have a short name (like x and y) or a more descriptive name (age, carname, total_volume). Rules for Python variables:
• A variable name must start with a letter or the underscore character
• A variable name cannot start with a number
• A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and )
• Variable names are case-sensitive (age, Age and AGE are three different variables)

Basic Types in Python - numbers(integers, floating), boolean, strings

Example 1 :
name = "Jahnavi"
age = 20
print(name)
print(age)



Example 2 :
name = "Jahnavi"
age = 20
name = "Riya"
age = 14
print(name)
print(age)


Example 3 :
first_name = "Jahnavi"
last_name = "Raghava Singh"
age = 19
is_adult = True
print(first_name + " " + last_name)
print(age)
print(is_adult)



Taking Input

name = input("What is your name? ")
print("Hello " + name)
print("Welcome to our cool Python class")

Example :

Favhero = input("What is your fav name? ")
print(Favhero)
