python list to set code example

Example 1: add list to set python

set.update() or |=

>>> a = set('abc')
>>> l = ['d', 'e']
>>> a.update(l)
>>> a
{'e', 'b', 'c', 'd', 'a'}

>>> l = ['f', 'g']
>>> a |= set(l)
>>> a
{'e', 'b', 'f', 'c', 'd', 'g', 'a'}

Example 2: how to convert a set to a list in python

my_set = set([1,2,3,4])
my_list = list(my_set)
print my_list
>> [1, 2, 3, 4]

Example 3: convert list to set python

names = ['Barry', 'Alice', 'Bob', 'Bob']

unique_names = set(names)
# Result:
# {'Alice', 'Barry', 'Bob'}

Example 4: python set to list

pokemon_set = set(['Pikachu', 'Bulbasaur', 'Koffing' , 'Spearow', 'Vulpix'])
print(pokemon_set)
pokemon_list = list(pokemon_set)
print(pokemon_list)

Example 5: data = a &b python

#!/usr/bin/python

a = 60            # 60 = 0011 1100 
b = 13            # 13 = 0000 1101 
c = 0

c = a & b;        # 12 = 0000 1100
print "Line 1 - Value of c is ", c

c = a | b;        # 61 = 0011 1101 
print "Line 2 - Value of c is ", c

c = a ^ b;        # 49 = 0011 0001
print "Line 3 - Value of c is ", c

c = ~a;           # -61 = 1100 0011
print "Line 4 - Value of c is ", c

c = a << 2;       # 240 = 1111 0000
print "Line 5 - Value of c is ", c

c = a >> 2;       # 15 = 0000 1111
