The dictionary unpacking operator (**) is an awesome feature in Python. It allows you to merge multiple dictionaries into a new one, as you did in the example above. Once you’ve merged the dictionaries, you can iterate through the new dictionary as usual....
Dictionaries are widely used in Python for various applications such as counting occurrences, grouping data, and storing configurations. Despite their versatility, there’s no built-in add method for dictionaries. Instead, there are several ways to add to and update a dictionary, each with its own...
Keys in dictionaries A Python dictionary key can be nearly any Python object. I say “nearly” because the object in question must behashable, meaning that it must have ahash value(the output of its__hash__()method) that does not change over its lifetime, and which can be compared to...
