How to use the get() method

Answer 1

Hello Marcos

this method is used for dictionaries.

get.(key, value)
key -> required, returns the value of the key
value -> optional, a value to return if the key does not exist

dict = {"a":1,"b":2}
print(dict.get("a")) #output: 1
print(dict.get("c")) #output: None
print(dict.get("c",0)) #output: 0

Hope this helps.

The get() method in Python is used with dictionaries to retrieve the value associated with the given key.

Syntax looks like this:

dictionary.get(key,default_value)

key:The key we want to lookup in dictionary.

default_value:This is optional and returns the provided value if key isn't found.If omitted it returns None.

It's also bit safer than directly accessing key using dictionary[key] as it doesn't raise a KeyError if the key isn't present.Instead it returns a default value or None if default value isn't provided.

Answer 3

The get() method is used to retrieve values from a dictionary. It's safer than direct indexing because it avoids errors if the key doesn't exist.

Example:

Python

my_dict = {'apple': 2, 'banana': 3}

# Get the value for 'apple'
value = my_dict.get('apple')
print(value) # Output: 2

# Get the value for 'grape' (not in the dictionary) with a default value
value = my_dict.get('grape', 0)
print(value) # Output: 0

hy@ Marcos..To use the "get()" method, you access it on a dictionary object, provide the key you want to retrieve the value for, and optionally specify a default value to return if the key doesn't exist in the dictionary; the syntax is: "dictionary.get(key, default_value)".
