Chapter 2.1 Introduction DataTypes in Python - Technology369kk

 

Introduction DataTypes:  

Well Python supports multiple data types:

  1. int: Integer numbers (e.g.,     10)
  2. float: Decimal numbers (e.g.,    3.14)
  3. str: String (e.g., "Hello")
  4. bool: Boolean (e.g., True, False)
  5. list: Ordered collection (e.g., [1, 2, 3])
  6. tuple: Immutable ordered collection (e.g., (1, 2, 3))
  7. dict: Key-value pairs (e.g., {"name": "Shailesh", "age": 25})
  8. set: Unordered collection of unique items (e.g., {1, 2, 3})
Dear Read We are discuss in Details Every Datatype examples:  

  •  int (Integer) :  Stores whole numbers(positive or negative) 


age = 23
print(age)      #output= 23


  • float (floating Point): Stores decimal numbers. 

pi = 3.14
print(pi)  # Output: 3.14

  • str(String) : Stores a sequence of character. 
  • We are discuss about string details in next chapter. 


greeting = "Hello, Shailesh!"
print(greeting)  # Output: Hello, Shailesh!

 

  •     bool (Boolean)  :- Represents either True or False

is_logged_in = True    #Boolean
print(is_logged_in)  # Output: True


  • list :  An ordered, mutable collection of elements. 

fruits = ["apple", "banana", "cherry"]   #list
print(fruits)  # Output: ['apple', 'banana', 'cherry']


  • tuple:  An order, immutable collection of elements

coordinates = (10, 20, 30)   #tuples
print(coordinates)  # Output: (10, 20, 30)
  • dict( Dictionary)  :- Stores key value pairs.


person = {"name": "Shailesh", "age": 25}    #dictionary
print(person)  # Output: {'name': 'Shailesh', 'age': 25}

  • set:  An unordered collection of unique items. mathematics bala set just imagine set chapter 1 class 11th. 
unique_numbers = {1, 2, 3, 2, 1}    #set
print(unique_numbers)  # Output: {1, 2, 3}


Guys Each of these data types serves different purposes and can be used based on the requirements of your program based so, hope this is helpful for you.
