data = [2, 5, 3, 2, 2, 9] 
data.sort() 
print(data)

Output: [2, 3, 5, 9, 22]

LIST REVERSE

data= [2, 3, 5, 7] 
data.reverse() 
print('Reversed List:' , data)

Output: Reversed List: [7, 5, 3, 2]

LIST REMOVE

data = ["Code" , "With" , "Rushi", 23] 
data.remove(23) 
data.remove("Rushi") 
print(data)

Output: ['Code', 'With']
