如何从列表中的元组中的元素创建字符串

Question

Is there a more succinct way to do this?

MyList = [(1,2,3),(6,6,7)] # example
msg = "";
for (a,b,c) in MyList:
   msg += str(b)

Answer 1

Yes, join .

str_msg = "".join([str(b) for (a,b,c) in MyList])

Where the starting quotes contain any delimiter you might want to use between elements and where MyList is some collection of string items.
