问题描述
在Python 3.3中,我在执行此行时遇到错误:
In Python 3.3 I am getting an error while executing this line:
print ("Message from server : ") + msg
其中 msg
(尝试做套接字编程,你可能猜到)
where msg
is received data from server (Trying to do socket programming as you might guess)
推荐答案
print()
在Python 3中返回无
。所以,你试图连接(或添加)无
print()
returns None
in Python 3. So, you're trying to concatenate(or add) None
with msg
, which results in an error.
尝试字符串格式化:
print ("Message from server : {}".format(msg))
