If you have a dict-like object {‘apple’: 1, ‘banana’: 2} and want to transform it into a MutableMapping, this article guides you through it. Method 1: … Read more

5 Best Ways to Convert a Python Dictionary to a List of Tuples

πŸ’‘ Problem Formulation: Converting a Python dictionary to a list of tuples is a common task that allows the conversion of key-value pairs into a structured list format. This can be advantageous when preparing data for functions that require tuple inputs, or for various sorting operations. For example, given a dictionary {‘apple’: 1, ‘banana’: 2}, … Read more

5 Best Ways to Convert Python dict to namedtuple

πŸ’‘ Problem Formulation: Converting a Python dictionary to a namedtuple can enhance readability and accessibility by providing dot-access to dictionary elements. For instance, given a dictionary {‘name’: ‘Alice’, ‘age’: 30}, the desired output is a namedtuple with fields ‘name’ and ‘age’ that allows access like person.name and person.age. Method 1: Using the collections.namedtuple Function This … Read more
