Convert List of String to a String separated by a delimiter

Question

Whats the best way to convert a list(of string) to a string with the values seperated by a comma (,)

Answer 1

My solution:

string = ["a","2"]\n
newstring = ""
endOfString = len(string)-1
for item in string:
    newstring = newstring + item
if item != string[endOfString]:
    newstring = newstring ","'
