How Can I Unpack Lists as Arguments in Python Functions?

Unpacking List Arguments in Functions

When passing arguments to a function, Python allows you to provide a list of items. However, if the function expects individual strings, passing a list directly will result in errors. To resolve this issue, you can employ the concept of list unpacking.

To unpack a list into separate arguments for a function, use the asterisk (*). This expands the list and passes each element as an individual argument. For instance, consider the following:

my_list = ['red', 'blue', 'orange']
function_that_needs_strings(*my_list) # works!

In this example, the asterisk unpacks my_list, effectively passing 'red', 'blue', and 'orange' as separate arguments to function_that_needs_strings.

Furthermore, note that this technique can be used with other iterable objects, such as tuples and dictionaries, to conveniently pass multiple values to functions.
