Accessing the Elements of a Set

Since a set is an unordered collection, you can't access its elements by index because they don't have indices. However, you can verify whether an element exists within the set using the in keyword.

It's especially handy to use the in keyword with a for loop. Let's check out an example.

1234
set_1 = {"green", "red", "white", "blue", "black"} for i in set_1: print(i)
1234
set_ = {"green", "red", "white", "blue", "black"} print("red" in set_) print("yellow" in set_)

Task

Here's your set:

You need to determine if "pear", "banana", and "lemon" are in the set.
