What is a Variable?
- Variables are used to store information to be referenced and manipulated in a computer program
- We use "=" symbol to assign a value to a variable
var1 = value
Variable Name Rules
- The variable name must start with [a-z][A-Z]or _(underscore) followed with any number of characters from [a-z][A-Z][0-9] or _(underscore)
- Variable names are case sensitive("SACHIN" is not same as "sachin")
- There are some python keywords reserved for a special purpose . We should avoid using those keywords as a variable name.(keyword-list)
Dynamic type binding
- Unlike other strongly-typed programming languages like C,C++ JAVA etc where we have to define variable along with data type they are going to hold, is not required in Python
