Combine array into one string [duplicate]

Question

I want to be able to combine a variable length array into a single string, for example:

var1 = ['Hello',' ','World','!']

becomes:

var2 = 'Hello World!'

and the first array may be bigger than 4. Thanks for any help!

Answer 1

str.join()

Return a string which is the concatenation of the strings in the iterable iterable. The separator between elements is the string providing this method.

List items will be joined (concatenated) with the supplied string. Using '' will join all items with no character between them.
