Question

The _________ dictionary method returns the value associated with a specified key. If the key is not found, it returns a default value.

value()
get()
key()
pop()

Answer 1

The get() method is used to retrieve a value for a given key from a dictionary in Python. If the key does not exist, it returns a default value given as a second argument. This helps to avoid KeyErrors for absent keys.

Step-by-step explanation:

The get() dictionary method returns the value associated with a specified key in Python. If the key is not present in the dictionary, it allows a default value to be returned instead of raising a KeyError. This makes the get() method very useful when you're not sure if a key exists within the dictionary.

For example, let's say we have a dictionary called fruit_prices with keys representing fruit names and values representing prices:

{'apple': 1.2, 'banana': 0.5}

If we want to access the price of 'apple', we can use fruit_prices.get('apple'), which will return 1.2. However, if we try to access a fruit that's not in the dictionary, like 'cherry', using fruit_prices.get('cherry', 'Not Found') will return 'Not Found'.
