None is a special data type in Python that represents the absence of any value or object. It is not the same as 0, False, or an empty string.
List comprehension is a concise way of creating lists in Python based on an existing iterable object, such as a list, a tuple, a string, or a range.
Type hints don't enforce type checking at runtime, but they provide valuable information for static type checkers, code completion, and code clarity for developers.
In summary *args collects the extra positional arguments as a tuple, while **kwargs collects the extra keyword arguments as a dictionary.
Python can be used to automate various tasks, and sometimes these tasks involve interacting with the underlying operating system.
This verification is essential for ensuring that the subsequent operations or functions are appropriate for the data structure at hand.
Python 3.8 and earlier require importing `Tuple` from the `typing` module. Python 3.9+ allows using `tuple` directly without importing.
You can use the % operator, format method, or f-strings to perform string interpolation, which is inserting values into a string in Python.
This is a common error in Python that occurs when you try to use a variable that has not been assigned a value in the local scope of a function.
