15 Απρ 2015 · You can use .update() to combine set b into set a. Try this: a = {'a', 'b', 'c'} b = {'d', 'e', 'f'} a.update(b) print(a) To create a new set, c you first need to .copy() the first set: c = a.copy() c.update(b) print(c)
There are several ways to join two or more sets in Python. You can use the union() method that returns a new set containing all items from both sets, or the update() method that inserts all the items from one set into another:
19 Μαρ 2023 · Depending on the result you want to achieve, there are four ways you can combine two or more sets as one in Python. To combine all unique values from the sets, use the union() method. To combine values present in the sets, use the intersection() method.
There are several ways to join two or more sets in Python. The union() and update() methods joins all items from both sets. The intersection() method keeps ONLY the duplicates.
18 Ιουλ 2022 · You can also use the | operator to concatenate two sets (union in set theory): >>> my_set = {1} >>> my_set = my_set | {2} >>> my_set {1, 2} Or a shorter form using |=: >>> my_set = {1} >>> my_set |= {2} >>> my_set {1, 2} Note: In versions prior to Python 2.7, use set([...]) instead of {...}.
Python provides us with various built-in methods to merge sets. Sets are very much useful when we have to perform mathematical operations like union, intersection, difference, symmetric difference, etc. In this tutorial, we will learn about the different approaches to merge sets.
Most, though not quite all, set operations in Python can be performed in two different ways: by operator or by method. Let’s take a look at how these operators and methods work, using set union as an example.
