2020-12-02 · The methods dict.keys() and dict.values() return lists of the keys or values explicitly. There’s also an items() which returns a list of (key, value) tuples, which is the most efficient way to examine all the key value data in the dictionary. All of these lists can be passed to the sorted() function.

Dictionary is one of the important data types available in Python. The data in a dictionary is stored as a key/value pair. It is separated by a colon(:), and the key/value pair is separated by comma(,). The keys in a dictionary are unique and can be a string, integer, tuple, etc. The values can be a list or list within a list, numbers, string, etc.

We use the index and values functions of dictionary collection to achieve this. You can easily swap the key,dictionary pairs in Python, with a one liner. dict = {value:key for key, value in dict.items()} So in practice you can have something like this: def check_key_exist(test_dict, key): try: value = test_dict[key] return True except KeyError: return False def main(): # Dictionary of string and int for key, value in my_dict.items(): print(key,':',value) It is important to note that in older Python 2 versions where items() , keys() , and values() returned a copy of data from a dictionary . While in Python 3 they return a view object.
