Join a string using delimiters

Question

What is the best way to join a list of strings into a combined delimited string. I\'m mainly concerned about when to stop adding the delimiter. I\'ll use C# for my example

Answer 1

For python be sure you have a list of strings, else ','.join(x) will fail. For a safe method using 2.5+

delimiter = '","'
delimiter.join(str(a) if a else '' for a in list_object)

The "str(a) if a else ''" is good for None types otherwise str() ends up making then 'None' which isn't nice ;)
