Multiple Function Arguments (learnpython.org)

Multiple function arguments in Python enable functions to accept an arbitrary number of arguments, providing flexibility and adaptability. There are two types of multiple function arguments: positional arguments and keyword arguments. Positional arguments are defined by their position, while keyword arguments are identified by their corresponding keywords.

#Multiple Function Arguments
def myfunction(first, second, third):
    # do something with the 3 variables
    ...

The use of multiple function arguments allows developers to create functions that can handle different numbers of inputs. This flexibility enables the creation of functions that adapt to specific requirements, making them highly customizable. By leveraging multiple function arguments, developers can build functions that suit a wide range of scenarios without the need for separate implementations.

#Multiple Arguments
def foo(first, second, third, *therest):
    print("First: %s" % first)
    print("Second: %s" % second)
    print("Third: %s" % third)
    print("And all the rest... %s" % list(therest))

Multiple function arguments empower developers to create dynamic functions that can handle various scenarios and adapt on-the-fly. By accepting an arbitrary number of arguments, functions can process different amounts of data or respond to changing requirements. This dynamic nature allows for the creation of reusable and versatile functions.

#Calling the 'Foo' Function
def foo(first, second, third, *therest):
    print("First: %s" %(first))
    print("Second: %s" %(second))
    print("Third: %s" %(third))
    print("And all the rest... %s" %(list(therest)))

foo(1, 2, 3, 4, 5)

#Argument Order Flexible
def bar(first, second, third, **options):
    if options.get("action") == "sum":
        print("The sum is: %d" %(first + second + third))

    if options.get("number") == "first":
        return first

result = bar(1, 2, 3, action = "sum", number = "first")
print("Result: %d" %(result))

Using multiple function arguments enhances the interface of functions by providing clear and expressive ways to pass inputs. By utilizing keyword arguments, developers can provide additional context and make the function calls more self-explanatory. This improves code readability and reduces the chances of errors when invoking functions with multiple arguments.

#Code Completed
def foo(a, b, c, *args):
    return len(args)

def bar(a, b, c, **kwargs):
    return kwargs["magicnumber"] == 7

# test code
if foo(1, 2, 3, 4) == 1:
    print("Good.")
if foo(1, 2, 3, 4, 5) == 2:
    print("Better.")
if bar(1, 2, 3, magicnumber=6) == False:
    print("Great.")
if bar(1, 2, 3, magicnumber=7) == True:
    print("Awesome!")

Multiple function arguments in Python offer a powerful toolset for creating dynamic, adaptable, and customizable functions. By embracing the flexibility of positional and keyword arguments, developers can build functions that handle varying numbers of inputs and respond to changing requirements. Understanding and utilizing multiple function arguments allows for the creation of more versatile and expressive functions in Python, enhancing code reusability and readability.
