“def” is the keyword used to define a function in Python. “function_name” is the name you give to your function. It should follow the variable naming rules in Python. “parameter1”, “parameter2”, etc., are optional input values (also called arguments) that the function can accept...
As you expect it, Python has also its own way of passing variable-length keyword arguments (or named arguments): this is achieved by using the**kwargssymbol. When using **kwargs, all the keywords arguments you pass to the function are packed inside a dictionary. And, as you expect it...

To use the argument, I merely need to specify the argument in the method definition. What often confuses me is that I don't need to specify arguments in theconnectstatement. The example below emits a signaldidSomethingand passes two arguments,"important"and"information"to theupdate_labelmethod...
Functions In Python Parameters in Function Keyword Arguments In Functions Default Argument ValuesA function is a block of organized, reusable code. Functions simplify the coding process, prevent redundant logic, and make the code easier to follow and allow you to use the same code over and over ...
If you want to provide a default value for an argument, make sure it comes after all the required arguments. def example_function(b, a=1): pass In this example, we have fixed the error by placing the non-default argument b before the default argument a. Examples and Expl...
You don’t have to define the sorted() function. It’s a built-in function that’s available in any standard installation of Python. You’re ordering the values in numbers from smallest to largest when you call sorted(numbers). When you pass no additional arguments or parameters, sorted()...
Passing functions as arguments to other functions Functions can also be passed as parameters to other functions. Let's illustrate that below. def plus_one(number): return number + 1 def function_call(function): number_to_add = 5 return function(number_to_add) function_call(plus_one) Power...
Two more ways to define and pass arguments in Python are*argsand**kwargs. Using the single asterisk*or double asterisk**syntax before a parameter name in a function header allows you to pass a varying number of non-keyword or keyword arguments in a function call. Note that*argsstands for...
