Python's variable is dynamic type,is it? But why this can't work? >>> 3 + 'a' Traceback (most recent call last): File "<stdin>", line 1, in ? TypeError: unsupported operand type(s) for +: 'int' and 'str'
So I see the number 3 can't be converted to string type automacially. -- http://mail.python.org/mailman/listinfo/python-list
