"""
What is an variable?
-> it is a container to store the data 

Data Types ->

primitive Data Types--->
Integers->
Whole Number 
Natural Number 
Negative Number 


Float->
 Real Numbers 
 Rational Numbers 

Char ->'a' , 'b' , 'c' , '{' , '-' , '0'
1 byte

Boolean -> True or false


Non primitive Data types->
1. String: "delhi"
2. list: [1,2,3,"delhi","hello",4.5]
3. Dictionary: {"Raman":24 , "gracy":22}
4. Tuple: (a,b,c)
5. Sets : set()
"""

"""
Naming Variables:
1. No identifiers/keywords can be used for nomination, example are print , if ,else , for while
2. No predefined function names can be used as variables , print() , input() , map(), int()
3. Should not start from numbers 1,2,3,4
4. Can be started with _ but not with other special characters.
5. Internal space not allowed 
6. Case sensitive 


Case notation:
-> Snake_Case : Less_ordinary 
-> camelCase: lessOrdinary

#Q2:- Create a variable 'city' with the value 'delhi' .
city="Delhi"

#Q3:- Assign value 100 to variables x,y,z in one line . print them 
x,y,z=100,100,100
