所以，這裏是一個函數裏面的代碼塊：的Python：無法理解這樣的語法錯誤
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-- : ')
所有這一切都被嵌套在一個try ... except語句。不管我放置i + = 1 - >例如打印（'ho ho ho'），都會被拒絕爲'SyntaxError：invalid syntax'。
我一直停留在這2天，並不能找出這裏發生了什麼導致這個錯誤...
編輯：更多的代碼，如要求：
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 : ')

也許混合製表符和空格導致不可見的縮進錯誤？ – RemcoGerlich
你能發佈實際錯誤嗎？圍繞該錯誤消息應該有更多，例如，行號等。 – hansaplast
不幸的是，一切都很完美。 –
