you can write your Python program to accept command line arguments when executing the Python code file. For example, you can run a Python code file with arguments likepython index.py arg1 arg2. Then, you can usearg1andarg2values to do some operations in your Python code. ...
That can come in handy, but with the particular function we’ve written here it’s most clear to use all positional arguments or all keyword arguments. Why use keyword arguments? When calling functions in Python, you’ll often have to choose between using keyword arguments or positional argumen...

Sys.Argv List Example in Python To use sys argv, you will first have to import the sys module. Then, you can obtain the name of the Python file and the value of the command line arguments using the sys argv list. The sys.argv list contains the name of the Python file at index 0....
You’ll cover the optional arguments key and reverse later in the tutorial. The first parameter of sorted() is an iterable. That means that you can use sorted() on tuples and sets very similarly: Python >>> numbers_tuple = (6, 9, 3, 1) >>> sorted(numbers_tuple) [1, 3, 6,...
Why you’d useany()instead ofor If you would like to continue learning about conditional expressions and how to use tools likeorandany()in Python, then you can check out the following resources: operator.or_() all() whileloops Mark as Completed ...

In Python, *args and **kwargs are special syntax used in function definitions to handle a varying number of positional and keyword arguments, respectively. They provide flexibility when defining functions that can accept a variable number of arguments without having to explicitly specify them in ...
Function arguments are handy, but some functions can benefit from accepting a variable number of arguments. Named keyword arguments can make your code more readable and easier to use. You should embrace Python's *args and **kwargs arguments. They are pretty simple to use, and with them, you...
