Single Return Value

A single return value of a function in Python refers to returning a single object or value from a function. This type of return value has been used in previous sections.


              12345
            
def add_numbers(a, b):
    return a + b

result = add_numbers(3, 5)
print(result)  # outputs: 8

The function add_numbers takes two arguments, adds them, and returns a single value — their sum. In this example, the result is stored in the variable result and printed to the console.

Note

The join() function in Python is used to join the elements of an iterable, such as a list, into a single string. Learn more about the join function here.

Your task is to complete the function so that it merges strings from different lists and returns the resulting string as output:

You have to use arbitrary arguments because we don't know the number of lists to merge.
Iterate all lists to merge the strings inside the function body.
Return the resulting string using return keyword.
