What is the function of the ‘keys’ method in Python?

In Python, the keys() function is a method used to obtain all keys in a dictionary. It returns an iterable object containing a list of all keys in the dictionary. This method can be used to iterate through the keys of a dictionary or to determine if a specific key exists in the dictionary. It is important to note that the order of keys returned by the keys() method is not guaranteed, as dictionaries themselves do not preserve the order of keys. If it is necessary to iterate through the keys of a dictionary in a specific order, the sorted() function can be used to sort the result of the keys() method.
