Code Explanation:
Initialization of my_dict:
my_dict = {"a": 1, "b": 2, "c": 3}
Here, you're creating a dictionary called my_dict with three key-value pairs:
"a" is mapped to 1
"b" is mapped to 2
"c" is mapped to 3
So, initially, the dictionary looks like this:
{"a": 1, "b": 2, "c": 3}
Using the popitem() method:
result = my_dict.popitem()
The popitem() method removes and returns a randomly selected key-value pair from the dictionary.
It also removes that key-value pair from the dictionary.
After calling popitem(), my_dict is modified and loses one of its items.
For example, let's assume the last inserted item is ("c", 3) (which is usually the case in Python 3.7+). So after this call:
result will be the tuple ("c", 3)
The updated dictionary my_dict will look like this:
{"a": 1, "b": 2}
Printing result:
print(result)
This prints the key-value pair that was removed from my_dict by popitem(). In our example, it will
print:
('c', 3)
Output:
('c', 3)
