Python Various Variables

Sr. No.	Variable Name	Description	Example
1.	Integer Value denoted with         (int)	Whole numbers without decimals	x = 1
2.	Float  Value denoted with (float)	Numbers with decimals	y = 1.6
3.	String  Value denoted with (str)	Text enclosed in quotes	name = "iah"
4.	Boolean Value denoted with (if) , (elif) , (else) it means true / false	True or False values	age = Valid   (Above 18)    age = Not Valid   (Not Above 18)
5.	List  Value denoted with (list)	Ordered collection of items	numbers = [1, 2, 3, 4, 5]
6.	Tuple Value denoted with (tup)	Immutable ordered   collection	coordinates = (10, 20)
7.	Dictionary Value denoted with (dict)	Key-value pairs	person = {'name': 'harsh', 'age': 21, 'gender': 'male'}
8.	Set Value denoted with (set)	Unordered collection of unique elements	unique_numbers = {1, 2, 3, 4, 5}

Each variable type has its own characteristics and use cases. For example, integers and floats are used for numeric operations, strings are used for text manipulation, Booleans are used for logical operations, lists and tuples are used for storing collections of data, dictionaries are used for storing key-value pairs, and sets are used for storing unique elements.

str = input ("Enter Name :")        #lets take any string

print(str)                          #print the string

print(type(str))                    #print the type of the string

#The output will show print results with strings

    

(Output is Shown Below)

4. Boolean : (Input Is Shown Below)

Code :

                    
#Lets print the age of the person using the boolean if/else statement

#Code by IAH (Infinity Aggarwal Harshul)

Age = int(input("Enter Age : "))      #Lets take the age of the person using user input value

if (Age >= 18):                       #if the person is equal to 18 then

    print("Age = Valid")              #print age of the person is valid

else :                                #else if the person age is not equal to 18 then

    print("Age = Not Valid")          #print age of the person is not valid

   

#The output will show the age of the person is valid or not using user input value

(Output is Shown Below)

5. List : (Input Is Shown Below)

Code :

                    
#Entering the numbers in the list and printing them out as a list

#Code by IAH (Infinity Aggarwal Harshul)

list =[ 1,2,3,4,5]      #taking a list of some numbers

print(list)             #print them in the list

   

#The output will show the numbers in the list

(Output is Shown Below)

6. Tuple : (Input Is Shown Below)

Code :

                    
#Entering the coordinates in the tuple and printing them out as a tuple

#Code by IAH (Infinity Aggarwal Harshul)

coordinates =(10,20)      #taking some random coordinates

print(coordinates)             #print them in the tuple

print(type(coordinates))

   

#The output will show the numbers in the tuple

(Output is Shown Below)

7. Dictionary : (Input Is Shown Below)

Code :

             #Testing User Input And Storing them in the dictionary and updating them with the new user input data

#Code by IAH (Infinity Aggarwal Harshul)

Name = input("Enter Name: ")         #Enter Name using the input string

Age = int(input("Age: "))            #Enter age of the user using the int input string

Gender = input("Gender: ")           #Enter gender of the user using the input string

dict = {                             #This dictionary contains the user input data

    "Name" : "a",                    

    "Age" : "b",

    "Gender" : "c"

}

dict.update({"Name" : Name})         #now let we upadte the dictionary with the new user data

dict.update({"Age" : Age})

dict.update({"Gender" : Gender})

print(dict)                          #print the dictionary with the updated user input data

#The output dictionary which contains the user input data will show upadted user input data

   

(Output is Shown Below)

8. Sets : (Input Is Shown Below)

Code :

                #Lets print some numbers in the set

These examples demonstrate how to create variables of different types in Python. Each variable type serves a specific purpose and has its own set of operations and methods that can be applied to it.
