Introduction
Retrieving a value from a dictionary is a common task in programming. A dictionary is a data structure that stores key-value pairs, where the key is used to access the associated value. In this case, the key is a tuple of two elements (‘B’, ‘A’) and the value is the one you are trying to retrieve. In this article, we will discuss how to get a value from a dictionary in the format (‘B’, ‘A’):value. We will look at different methods for retrieving the value, including using the get() method, using the [] operator, and using the in operator. We will also discuss how to handle errors that may occur when trying to retrieve a value from a dictionary.
Solution
You can use the dictionary’s get() method to retrieve the value associated with a given key. For example, if the dictionary is called my_dict, you can get the value associated with the key (‘B’, ‘A’) by using the following code:
value = my_dict.get((‘B’, ‘A’))
First of all you need to correct this:
d= {'D', 'V'): -5, (...) >> d= {('D', 'V'): -5, (...)
after doing it you just need to call it as:return d[('S', 'X')] or print d[('S', 'X')]
This should work. Otherwise just let us know

solved how do i get a value from a dictionnary format (‘B’,’A’):value
If you are looking to get a value from a dictionary format (‘B’,’A’):value, the best way to do this is to use the get() method. This method allows you to specify a key and a default value, and it will return the value associated with the key if it exists, or the default value if it does not. For example, if you have a dictionary my_dict with the key-value pair (‘B’,’A’):value, you can use the following code to get the value:
value = my_dict.get('B', 'A')
The get() method is a great way to get values from dictionaries, as it allows you to specify a default value in case the key does not exist. This can help you avoid errors when trying to access values from a dictionary.
