Python Data Types

Data types in Python:

In Python, variables can hold the values of different types that are called data types. Python Data Types are used to define the operations and store each of them.

Built-in Data Types in Python:

There are five types of Python Data Types are exists:

1. Numbers: Numbers are refers to a numeric value. In Python, there are four types of numbers are exists.

  • integer
  • long integer
  • floating point
  • complex number
  • 2. String: String is a group of characters. In Python, you can use a string some following ways:

  • single quotes string: This string can be write as ‘Python’ .
  • double quotes string: This string can be write as “Python” .
  • triple quotes string: triple quotes string can be write as ”’Python”’ .
  • 3. List: Lists consists of items separated by commas and enclosed within square brackets([]). It is the most versatile data types in Python Programming Language.
    Example :

    list=['a','hello',25,3.14]
    print(list)
    

    Output :
    ['a','hello',25,3.14]
    

    4. Tuple: A tuple is also consists of a number of values separated by commas and enclosed within parenthesis. But you can’t change the values in a tuple. So, tuple is called read-only data type.
    Example :

    Tup=('a','hello',25,3.14)
    print(Tup)
    

    Output :
    ('a','hello',25,3.14)
    

    5. Dictionary: In Python, Dictionary is used to stores the data in key-value pairs. The key-values are basically strings and the value can be of any data type. The key value pairs are enclosed with curly braces({}) and each key-value pair is separated from the other using a colon (:).
    Example :

    Dict={"Student_Name":"Rohit","Roll_No":555)
    print(Dict["Student_Name"])
    print(Dict["Roll_No"])
    

    Output :
    Rohit
    555
