ValueError: zero length field name in format 

Answer 1

你正在使用python 2.6，在這裏你需要明確的編號格式字段。

對於Python 2.6，你需要改變你的代碼listen = ['{}:{}'.format(host, port)]到listen = ['{0}:{1}'.format(host, port)]

In python 2.7 '{} {}' is equivalent to '{0} {1}' so in python 2.7 you can use listen = ['{}:{}'.format(host, port)] , but not in python 2.6.
