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