Python set()

Python set() Class

The set() class in Python returns a new set object, optionally with elements taken from iterable.

Example 1

 # Python program explaining
 # the set() function
 # initializing list  
 list_val = [ 13, 14, 11, 14, 15 ] 
 # Printing iterables before conversion 
 print("The list value before conversion is : " + str(list_val)) 
 # Printing iterables after conversion 
 print("The list value after conversion is : " + str(set(list_val))) 

Output

The list value before conversion is : [13, 14, 11, 14, 15]
The list value after conversion is : {11, 13, 14, 15}

Example 2

 # Python program explaining
 # the set() function
 # initializing string list  
 str_list = ("apple", "banana", "cherry")
 # Printing iterables before conversion 
 print("The list value before conversion is : " + str(str_list)) 
 # Printing iterables after conversion 
 print("The list value after conversion is : " + str(set(str_list))) 

Output

The list value before conversion is : ('apple', 'banana', 'cherry')
The list value after conversion is : {'banana', 'apple', 'cherry'}
