The result of join is always a string, but the object to be joined can be of many types (generators, list, tuples, etc).
Once you learn it, it's very comfortable and you can do tricks like this to add parentheses.

Even if you are still using Python 2 you should write Python 3 ready code to make the inevitable upgrade easier. Although @Burhan Khalid's answer is good, I think it's more understandable like this:
The second argument to join() is optional and defaults to " ".

If you want to generate a string of strings separated by commas in final result, you can use something like this:

1 Without .join() method you can use this method:
So, range based for loop in this example , when the python reach the last word of your list, it should'nt add "-" to your concenated_string. If its not last word of your string always append "-" string to your concenated_string variable. answered Jul 7, 2020 at 11:03
Can you concatenate a list in Python?Python Lists are used to multiple items in one variable. Lists are changeable, ordered and it also allows duplicate values. The values are enclosed in square brackets. You can concatenate Lists to one single list in Python using the + operator.
How do you combine all elements in a list into a string?To convert a list to a string, use Python List Comprehension and the join() function. The list comprehension will traverse the elements one by one, and the join() method will concatenate the list's elements into a new string and return it as output.
