How to Add Element to a Set in Python
To add elements to a set in Python, you can use different methods.
The following examples show how to add an element to a set using different methods in Python.
Using add() Function
We can use the add() function to add a single element to a set.
Suppose we have the following set:
# Create a set
my_set = {"apple", "banana", "cherry"}
# Add a single element to the set
my_set.add("orange")
# Show set
print("Updated set after adding single element:", my_set)
Output: 👇️
Updated set after adding single element: {'banana', 'orange', 'cherry', 'apple'}
In this example, we use the add() function to add the element orange to the set.
Using update() Function
We can use the update() function to add a single element to a set.
Suppose we have the same set as above.
We can use the following code to add the element mango to the set:
# Add a single element to the set
my_set.update(["mango"])
# Show set
print("Updated set after adding single element:", my_set)
Output: 👇️
Updated set after adding single element: {'mango', 'apple', 'banana', 'cherry'}
In this example, we use the update() function to add the element mango to the set.
Using | Operator
We can use the | operator to add a single element to a set.
Suppose we have the same set as above.
We can use the following code to add the element lime to the set:
# Add a single element to the set
my_set = my_set | {"lime"}
# Show set
print("Updated set after adding single element:", my_set)
Output: 👇️
Updated set after adding single element: {'apple', 'banana', 'cherry', 'lime'}
In this example, we use the | operator to add the element lime to the set.
