Datatype in python programming language
In this tutorial, we will discuss the concept of datatype in python programming language
Python datatype
Data types indicates the type of value and how the value can be used in programs. Data type is used to allocate memory location in memory. For future use of stored data, variables are given a unique name to identify different memory locations. There is no need to declare variables before using them in python, unlike other languages. However, access to the data (content) is via variable name (variable identifiers) in python.
Eg
your_age=34
34 is Assigned to the variable Your_age
Python has five type of data type or variable
- Numbers
- List
- Tuple
- String
- Set
- Dictionary
Numbers
- INT – int represents negative and positive integer value without decimal point
- Float – floating point represents negative and positive values represented with decimal point.
Eg – 17.5, 234.67, -456.4, -1000.23
List in Python
List is a very important and most used data type in python. List is a collection of ordered sequence items like the array data type.
Syntax
Syntax of list data type in Python
list_name=[Item 1,Item 2,Item 3,Item 4] ;
Example
Names=[“mathan”,”suthan”,”babu”,”nimal”];
Tuble in Python
Tuble is a collection of ordered sequence items like List data type in Python.
Syntax
Syntax of Tuble data type in Python
Tuble_name=(Item 1,Item 2,Item 3,Item 4);
Example
Names=(“mathan”,”suthan”,”babu”,”nimal”);
String in Python
We can use single quotes or double code to represent a String in Python. Multi line string can be denoted using triple quotes ”’ or “””
Example 1
When the above code is executed, it produceS the following results
Hello world python
Hello world python
Hello
world
python
Hello
world
python
Program 2
when the above code is executed, it produces the following results
hello welcom
hello welcom
hello welcom
to python
tutorial
hello welcom

Set in Python
Syntax
Syntax of set data type in Python
set_name={Item 1,Item 2,Item 3,Item 4} ;
Example
Names={“mathan”,”suthan”,”babu”,”nimal”};
Dictionary in Python
Dictionary is a data type which is an unordered collection of items. A dictionary has a pair of items such as a key and a value.
Example
ProgrammingLanguages={}
ProgrammingLanguages[“jdk”]=”java development kit”
ProgrammingLanguages[“html”]=”Hyper text markup language”
ProgrammingLanguages[“css”]=”cascading style sheet”
ProgrammingLanguages[“xml”]=”extensible markup language”
