Data Type in Python, What is Data Type in Python

The data type is used to provide a pattern, size, and memory allocation of data using variable, constant, and method.

Python uses data type internally in the program, no need to write a data type declaration in the program because python provides flexibility to the identifier to contain multiple types of data using a single name identifier.


a=10

a= "hello"

a= True


Type of Data type:-

Primitive Type:-  it is the primary data type of Python that is common for all programming languages.

 


1 int :-       a=10

2 float:-    a=12.34

3 String:-  Collection of Char's

1)  String With Double Quote:-

It used to declare outer String on Python Script.

s= "data"       



2)  String With Single Quote:-

It is used to declare inner String on Python Script.

s= 'data'            

3)  String With double quote three times

s= """data"""    it support paragraph pattern or multiline statements


4)  String with a single quote three times:-

It is used to provide a multiline comment block.

''' comment '''     multiline comment


Example of String -

a = "<h1 style='color:red'>Welcome</h1>"
print(a)

b = 'hello ahdfbjhdbfhfd'
print(b)

c = """ hello dkjfhdkhfgdhg fjidkjfdkjfgjkdfkdg fhgdhfg hdagfhjdgfdfdfhdfjh
          dfhgdhfg hjdg fhjdsg fhgdhfgdhjfghdgfhjdsgfhjdghjfgdhjfgdh """
print(c)



4 boolean:-

it is used to create checkpoint or true|false value in the variable

by default, if statement, loop statement return a boolean value


b = True

b= False


boolean type basically used on a conditional statement, loop statement


Most Important Question of Boolean Data Type:-

s = True
print(s+1)

s1 = False
print(s1+1)

print(s+s1)


Derived Data type:-



this type of data type is specially created for Python Script.


1  LIST:-  it is used to contain a set of elements using an index from 0 to size-1 whose value can be change

2 TUPLE:-  it is used to contain a set of elements using the index value pair whose value can not be changed

3 DICTIONARY:-  it is used to contain a set of elements using key: value pair 


4 Set:-  It is used to display elements randomly.


5 DATETIME:-  it is used to contain current data and time 


6 Class:-  it is used to create a User-define type


7 Complex:-  it is used to contain a complex number


a = 2+3j    j means iota 


........................................................................................................

Predefine function in Python for Data type


type():-   it is used to represent the data type of an identifier in Python. it returns Classname: Datatype under generic pattern.

If we want to display only data type name then python provides __name__ attribute to get the datatype.


a=10
print(type(a))
a=20.2
print(type(a))
a=2+3j
print(type(a))
a=(10,20)
print(type(a))
a=[10,20]
print(type(a))
a={'a':10,'b':20}
print(type(a))
a=True
print(type(a))
a='hello'
print(type(a))
a="hello"
print(type(a))
a="""hello"""
print(type(a))

int():-  this method is used to convert numeric String to integer

a= "123" 
a = int(a)  #123

float():-  this method is used to convert numeric float String or integer to float

a=12
a = float(12)  #12.0

a= "12.34"
a=float(a)  #12.34

str():-  this method is used to convert int, float type value to String type

a= 12
b=str(a)  #"12"

b = str(12.34)  #"12.34"


ord():-  to convert char to ASCII Code then we use ord().


A ----> 65

a ----> 97

0 ---> 48

9 --->  57


A  to Z      65 to 90

a to z        97 to 122

0 to 9        48  to 57

,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,


Chr():-    It is used to convert ASCII Code to char

a = 90

print(chr(a))     Z
