所以，这里是函数中的一大块代码：
print('Printing current values ...')
for key, modbusObject in jsonDict.items():
print("Object {} contains value {} and timestamp {}".format(key, modbusObject.value, modbusObject.timestamp))
print('Writing data for loop number '+str(i)+' ...')
# server.send_message_to_all(jsonDict)
#print('ho ho ho')
i += 1
cmd = raw_input('Change json data (y/n) ? --type \'exit\' to quit-- : ')
所有这些都嵌套在try ... except语句中。无论我代替i + = 1 - ＆gt; for exemple print（'ho ho ho'）被拒绝为'SyntaxError：invalid syntax'。
我已经被困在这2天了，无法弄清楚这里发生了什么导致这个错误......
编辑：根据要求提供更多代码：
def new_client(client, server):
print("New client connected and was given id %d" % client['id'])
server.send_message_to_all('hello foo')
# global jsonDict
# global i
while True:
print('Currently connected clients : ')
