Sets

The Python data type set is an unordered collection with no duplicate elements. The elements inside the set are separated by commas.

Examples

Extract values from a set

	
>>> my_set = {1, 2, 3, 8, 12}
>>> my_set
{8, 1, 2, 3, 12}
>>> a = {'test', 1, 'aaa', 4}
>>> print(a)
{1, 4, 'test', 'aaa'}
>>> 

Eliminate duplicate elements

	
>>> x = {1, 2, 1, 3, 3, 4, 8, 8, 5}
>>> print(x)
{1, 2, 3, 4, 5, 8}
>>> y = {'test','a','test','b','b',7,8,7,'c'}
>>> print(y)
{'b','test',7,8,'a','c'}
>>> 

Check for element

>>> my_set = {'green', 3, 'red', '7'}
>>> print(my_set)
{'7', 3, 'green', 'red'}
>>> 'red' in my_set
True
>>> 'blue' in my_set
False
>>> 3 in my_set
True
>>> '7' in my_set
True
>>>
