Data Types

In python we don't need to define the type of variable while declaring it. python provide us to know the type of Data using type() function.

For Example :

>>> a = 10

>>> b = 'ProgGeek'

>>> c = 1.1

>>> print(type(a))

<class 'int'>

>>> print(type(b))

<class 'str'>

>>> print(type(c))

<class 'float'>

>>>

Standart Data Type

Variables can hold different data type of values. for Example age must be stored in integer where name must be stored in string

python provide us different data types:

Numbers
String
List
Tuples
Dictionary

1.Numbers :

Number store numeric value.
python support 4 types of numeric data type.

int
float
long
complex (a+bj)

2.String :

String can string sequence of character
The ' + ' operator is used to concatenate two string.

>>> print('prog' + 'geek')

proggeek

the ' * ' operator is used to repetition of string.

>>> print('ProgGek' * 2)

ProgGekProgGek

printing Substring.

>>> str = 'Proggeek'

>>> print(str[0:2])

using this technique we will print multiple substring

print single character.

>>> str = 'Proggeek'

>>> print(str[0])

printing single character from string is done by using indexing

3.List :

list are similar to array.
list can contain data of different data type.
list are separated with a comma ( , ) and enclosed with brackets [ ].

>>> list = [100,"prog"]

>>> print(list)

[100, 'prog']

4.Tuples :

tuples is similar to the list.
tuples can contain data of different data type.
tuples are separated with a comma ( , ) and enclosed with parentheses ( ).

>>> tuples= (1,"proggeek")

>>> print(tuples)

(1, 'proggeek')

5.Dictionary :

Dictionary is set of key-values pair of item.
the item of Dictionary are separated with a comma ( , ) and enclosed with braces { }.

>>> dict = {1 : "prog" , 2 : "Geek" }

>>> print(dict)

{1: 'prog', 2: 'Geek'}

>>> print(dict.values())

dict_values(['prog', 'Geek'])

>>> print(dict.keys())

dict_keys([1, 2])

>>>
