Single Return Value

A single return value of a function in Python refers to the practice of returning a single object or value from a function. We have already used this type of return value in previous sections. Let's refresh our knowledge and solve a task.

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.

Tarea

Your task is to create a function that merges strings in different lists and returns the resulting string as an output.

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