In Python, a set is a fundamental class that is integrated into the language, and this function serves as the constructor for this class. It facilitates the creation of a new set utilizing the elements provided during the invocation. The function accepts an iterable as its parameter and produces a new set object. The syntax for the constructor is outlined below.
Python set Function Syntax
It has the following syntax:
set([iterable])
Parameters
- iterable: a set of elements that cannot be altered.
Return
It returns a new set.
Different Examples for Python set Function
Let’s examine a few instances of the set function to grasp its capabilities.
Python set Function Example 1
An illustrative example of generating a set from iterable elements.
# Python set() function example
# Calling function
result = set() # empty set
result2 = set('12')
result3 = set('logicpractice')
# Displaying result
print(result)
print(result2)
print(result3)
Output:
set()
{'1', '2'}
{'a', 'n', 'v', 't', 'j', 'p', 'i', 'o'}
Python set Function Example 2
Let’s consider an example to illustrate how the Python set function operates.
# Python set() function example
# Calling function
result = set(['12','13','15'])
result2 = set(('j','a','v','a','t','p','o','i','n','t'))
result3 = set({1:'One',2:'Two',3:'Three'})
# Displaying result
print(result)
print(result2)
print(result3)
Output:
{'15', '13', '12'}
{'n', 'v', 'a', 'j', 'p', 't', 'o', 'i'}
{1, 2, 3}
Python set Function Example 3
In this section, we will generate a collection of filtered elements. The function geteven is designed to return only the even numbers.
# Python set() function example
def geteven(data):
if data%2 == 0:
return data
evenval = filter(geteven,[2,5,6,9,8,4])
# Calling function
result = set(evenval)
# Displaying result
print(result)
Output:
{8, 2, 4, 6}
