You can convert a list of pairs into a dictionary quite simply using a dict() function in Python. ```python list_of_pairs = [('a', 1), ('b', 2), ('c', 3)] dictionary = dict(list_of_pairs) print(dictionary) ``` When you run this code, it will output: ``` {'a': 1, 'b': 2, 'c': 3} ``` The dict() function is a built-in Python function that converts a list of tuples into a dictionary. Each tuple in the list forms a key-value pair in the dictionary. So in the given example, 'a', 'b', and 'c' became keys in the dictionary, and 1, 2, and 3 became their corresponding values. In terms of being Pythonic - using built-in functions when they do precisely what we need is in line with the philosophy of Python, so this approach is quite fitting. Remember, if you have duplicated keys in the pairs, the value in the dictionary will be the one that appears last in the list.
