Since functions can be passed into functions, that also means that functions can accept another function as an argument. Thefilterfunction assumes its first argument is a function. You can think of thefilterfun
Thekwargs syntax is used to pass a variable number of keyword arguments to a function. Thekwargs argument is treated as a dictionary of key-value pairs inside the function. Here is an example of how to usekwargs: Python defmy_function(**kwargs): forkey, valueinkwargs.items(): print(...
In computer programming, an argument is a value that is accepted by a function. Before we learn about function arguments, make sure to know aboutPython Functions. Example 1: Python Function Arguments def add_numbers(a, b): sum = a + b print('Sum:', sum) add_numbers(2, 3) # Output...

An analogous operation is available on the other side of the equation in a Python function call. When an argument in a function call is preceded by an asterisk (*), it indicates that the argument is a tuple that should be unpacked and passed to the function as separate values:...
If you declare your handler function with a single input argument, Lambda will raise an error when it attempts to run your function. The most common way to declare a handler function in Python is as follows: def lambda_handler(event, context): You can also use Python type hints in your ...
