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

Passing a List to a Function as Individual Arguments

When a function requires multiple string arguments, it is possible to pass a list of strings to the function instead of listing them individually. However, simply passing a list as an argument will result in an error.

To overcome this, Python provides the concept of "unpacking". By using the asterisk (*) operator before the list, the function will treat each element of the list as an individual argument.

Example:

my_list = ['red', 'blue', 'orange']

# Function that expects strings as individual arguments
function_that_needs_strings('red', 'blue', 'orange')  # Works!

# Use the asterisk (*) operator to unpack the list
function_that_needs_strings(*my_list)  # Works!

How it Works:

When the asterisk is used before a list, the function is passed the elements of the list as individual arguments. In the above example, 'red', 'blue', and 'orange' are passed to the function as three separate strings, allowing the function to process them accordingly.
