How Can I Pass a List of Strings as Individual Arguments to a Python Function?

Passing Lists as Multiple Function Arguments

Consider a scenario where you encounter a function that requires individual strings as arguments, but you only have a list of strings. If you attempt to pass the list directly to the function, you'll encounter an error.

Unpacking Argument Lists

To resolve this issue, Python offers a feature called "unpacking argument lists." By using this technique, you can expand the list and pass the individual strings as separate arguments.

To achieve this, simply prepend the list with an asterisk (*):

function_that_needs_strings(*my_list) # works!

In this example, the asterisk will unpack the 'my_list' into individual strings, effectively passing 'red', 'blue', and 'orange' as separate arguments to the 'function_that_needs_strings'.

For more in-depth information on unpacking argument lists, refer to the official Python Tutorial:
