data type

[0]
In computer science and computer programming, a data type or simply type is
anattribute of data which tells the compiler or interpreter how the 
programmer intends to use the data. Most programming languages support basic
data types of integer numbers (of varying sizes), floating-point numbers 
(which approximate real numbers), characters and Booleans. A data type 
constrains the values that an expression, such as a variable or a function, 
might take. This data type defines the operations that can be done on the
data, the meaning of the data, and the way values of that type can be
stored. A data type provides a set of values from which an expression 
(i.e. variable, function, etc.) may take its values.


[1]
Data types are used within type systems, which offer various ways of
defining, implementing, and using them. Different type systems ensure varying
degrees of type safety.

Almost all programming languages explicitly include the notion of data type,
though different languages may use different terminology.

Common data types include:

Integer
Floating-point number
Character
String
Boolean

#simple intrest in python
P=float(input('principle amount:'))
R=float(input('rate:'))
T=int(input('Time:'))
SI=(P*R*T)/100
print('simple intrest=',SI)
#output:
principle amount:
rate:
Time:

A data type, in programming, is a classification that specifies which type of 
value a variable has and what type of mathematical, relational or logical 
operations can be applied to it without causing an error.
