What are Variables? 

Variables are names given to a computer memory location in order to store data in a program to run it. The values can be known or unknown in a program. They act like containers that become full when data is give to them. They also label the data they are holding.
                                                      










Creating a Variable

Creating a variable is also known as declaration of a Variable. To declare a variable we need to first tell the variable name and then tell which type of data it is holding. But some programing languages like Python, Perl, PHP, ect- don't need to specify the type of data the Variable is holding.

It also makes it easy to categorize the data stored.  Types of Datatypes:- Primitive Datatype- These are predefined datatypes that are independent of all other kinds and include basic values of particular attributes, like text or numeric values . They are the most fundamental type and are used as the foundation for more complex datatypes. Composite Datatypes- These datatypes are made put of various primitive kinds that are mostly supplied by the user. They are also called as non-primitive datatypes User Defined Datatypes- This datatype is derived from an existing datatype. Anyone can create their own. Examples of Datatypes:- String- Represents a sequence of characters like "House" and "863218" Integer- Represents Whole numbers like 24 and -7 Float- Represents a fractional or decimal numbers Boolean- Represents true or false option Reference- Data Types in Programming...

Addition:- Multiplication:- Conditional operator It is an operator that has a condition which means that it has 2 choices whether yes or no. Examples are:- If and Else Elif While Relational Operator Relational operators in Python are used to compare values and are also known as comparison operators too. "==" Checks if the values are same "!=" Checks if the values are not the same ">" Checks if the value on the left is greater than the value on the right  "<"  Checks if the value on the right is greater than the value on the left "<="Checks if the left value is less or equal to the right value ">=" Checks if the right value is less or equal to the left value
