How to Combine Two Sets in Python with a For Loop in Reverse and One Line with Space?

To combine two sets in Python using a for loop in reverse and a one-liner with space, you can use the following approaches:

1. Using a for loop in reverse:

To combine two sets in Python using a for loop in reverse and a one-liner with space, you can use the following approaches:

Using a for loop in reverse:

In this example, we create a copy of set1 using the copy() method. Then, we iterate over set2 in reverse using the reversed() function and add each item to the combined_set using the add() method.

2. Using a one-liner with space:

set1 = {1, 2, 3}
set2 = {4, 5, 6}
combined_set = set1 | set2

print(combined_set)

Here, we use the | operator, also known as the union operator, to combine set1 and set2. This operator performs a set union, resulting in a new set that contains all unique elements from both sets.

Note: The second approach using the union operator is the more concise and recommended way to combine sets in Python. It is generally more efficient than using a loop for large sets.

Choose the approach that best suits your needs based on the specific requirements of your program.
