Hello Programlanders .
I've been learning python for some time using 'Automate the boring stuff' ; I've been scaling through each topic successfully, not until I got to chapter 8 project where the knowledge of command line argument is to be employed in multiclipboard project.
The problem is I don't seems to understand handling command line arguments, as much was not written about it in the book. I've watched some YouTube videos but it's the same old story.
I'm using pycharm text editors.
len(sys.argv)==3 and sys.argv[1].lower()=='save':
for my program to work, the above condition must be true but my len(sys.argv) is always 1 thereby rendering my code useless.
I will really appreciate it if you can help me out or better still recommend any book that comprehensively explains HANDLING COMMAND LINE ARGUMENTS in python

If

len(sys.argv)

is returning 1, it means you only have one argument in the program which is the filename (or the executable).

sys.argv

returns a list with the first element being the filename followed by other arguments in the program. We'll be able to make significant contributions if you could share the whole code.

Meanwhile, you can go through these links, I hope you find them useful;

If you are using pycharm run, you need to set the arguments before running.
However, you can simply

1. Go into the project folder
2. Open cmd or powershell in that folder (shift + right click) and select appropriately.
3. Run py [file].py arg1 arg2

Wow! Thanks guys
