How to Filter Items of a Set based on a Condition in Python

How to Filter Items of a Set based on a Condition in Python ?

Answer

To filter items of a set based on a condition in Python, you can use list comprehension or the filter function to create a new set from the filtered items.

✐ Examples

1 Filtering Numbers Greater Than 5

In this example,

We create a set named numberSet using the curly braces syntax, which contains numeric values 1, 5, 10, 15, and 20.
We use list comprehension to filter the numbers greater than 5.
We convert the resulting list to a set using the set constructor, resulting in a new set named filteredSet.
Finally, we print filteredSet to see the filtered items.

Python Program

numberSet = {1, 5, 10, 15, 20}
filteredSet = {num for num in numberSet if num > 5}
print(filteredSet)

Output

{10, 15, 20}

2 Filtering Strings Containing 'a'

In this example,

We create a set named stringSet using the curly braces syntax, which contains string values 'apple', 'banana', 'cherry', 'date', and 'grape'.
We use list comprehension to filter the strings containing the letter 'a'.
We convert the resulting list to a set using the set constructor, resulting in a new set named filteredStringSet.
Finally, we print filteredStringSet to see the filtered strings.

Python Program

stringSet = {'apple', 'banana', 'cherry', 'date', 'grape'}
filteredStringSet = {string for string in stringSet if 'a' in string}
print(filteredStringSet)

Output

{'banana', 'apple', 'grape'}
