Using my_dict.get(key, default). What will this print?

Understanding Python Dictionary Manipulation with my_dict.get()

my_dict.get(key, default) is a method in Python used to retrieve the value associated with a specified key in a dictionary. This method takes two parameters: the key whose value is to be retrieved and a default value to return if the key is not found in the dictionary.

Let's consider the following Python code:

my_dict = dict(bananas=1.59, fries=2.39, burger=3.50, sandwich=2.99)
my_dict.update(dict(soda=1.49, burger=3.69))
burger_price = my_dict.get('burger', 0)
print(burger_price)

Final answer: The given Python dictionary manipulation results in the printing of the updated 'burger' value, 3.69.

Explanation:

The Python dictionary my_dict is initially defined with four key-value pairs: bananas, fries, burger, and sandwich. Subsequently, the update() method is used to insert a new element 'soda' into the dictionary and update the value of 'burger' from 3.50 to 3.69.

Next, the get() method is called on my_dict to retrieve the value of the key 'burger'. If the key 'burger' is not found in my_dict, the method will return the default value specified (0 in this case). However, since 'burger' exists in my_dict and has been updated to 3.69, that value will be returned by the get() method.

Consequently, the print statement will output 3.69.

What is the purpose of using my_dict.get(key, default) in Python dictionary manipulation? The purpose of using my_dict.get(key, default) in Python dictionary manipulation is to retrieve the value associated with a specified key from the dictionary. If the key is not found, the method returns the default value specified instead of raising an error.
