In the case of storing or transmitting data, it is better to do it in the form of a string rather than a list. For example, if you want to store a list of names in a file or database, you can convert the list to a string before saving it.
Some libraries or APIs require data to be passed as a string instead of a list. In these cases, you have to convert your list to a string before passing it to the library or API.
If you want to compare two lists, it may be easier to first convert them to strings and then compare the strings.
The main point to keep in mind while using this function is that the join function can convert only those lists into string that contains only string as its elements.
