python3按空格分割字符串_合并Python中用空格分割的字符串

我有一部分代码像这样&＃xff1a;

for line in response.body.split("\n"):

if line !&＃61; "":

opg &＃61; int(line.split(" ")[2])

opc &＃61; int(line.split(" ")[3])

status &＃61; int(line.split(" ")[5])

if command &＃61;&＃61; &＃39;IDENTIFY&＃39;:

if opg&＃61;&＃61;opcodegroupr and opc&＃61;&＃61;opcoder:

if status&＃61;&＃61;"0":

IEEEAddrRemoteDev &＃61; line.split(" ")[6:14]

ret[&＃39;success&＃39;] &＃61; "IDENTIFY: The value is %s " % (IEEEAddrRemoteDev)

self.write(tornado.escape.json_encode(ret))

self.finish()

变量’line’就像这样&＃xff1a;

1363011361 2459546910990453036 157 0 17 0 209 61 0 0 0 0 0 0 0 0 0 0 0 0 0 201

例如,我将从6到14中取字段并“合并”彼此以打印IEEEAddrRemoteDev,就像整个字符串一样.

这是

IEEEAddrRemoteDev &＃61; line.split(" ")[6:14]

正确的方法&＃xff1f;如果我写

print IEEEAddrRemoteDev

我什么都没得到.

这里有些不对劲…

解决方法:

你想使用join&＃xff1a;

ret[&＃39;success&＃39;] &＃61; "IDENTIFY: The value is %s " % (" ".join(IEEEAddrRemoteDev))

但是,更大的问题是您的状态&＃61;&＃61;“0”行永远不会为真(因为状态为int),将其更改为

if status &＃61;&＃61; 0:
