How To Use *args In A Function?

This may be a basic question, but unfortunately I was not able to get anything while searching. I have a function which uses *args to capture arguments when the function is run on

Solution 1:

sys.argv[1:] will give you all commandline arguments as a list.

So you could do func(*sys.argv[1:]) in your code to receive all the arguments. However, there is no good reason to use varargs - just make the function accept a list args and pass sys.argv[1:] directly.

Solution 2:

You would use similar syntax when calling the function:

func(*sys.argv[1:])

Here the * before the sys.argv list expands the list into separate arguments.

The sys.argv list itself contains all arguments found on the command line, including the script name; slicing it from the second item onwards gives you all the options passed in without the script name.
