Question

我想返回2个值：第一个是从连接到raspberry的传感器读取的数据，第二个是当前时间

rasp.py

#!/usr/bin/env python
from datetime import datetime
class ReturnValue(object):
  __slots__ = ["x","y"]
  def __init__(self,x,y):
    self.x = x
    self.y = y

def foo ( ) :
  i = 0 
  for i in range(0,19):
     i += 1
     tfile = open("/sys/bus/w1/devices/28-000007101990/w1_slave")
     text = tfile.read()
     tfile.close()
     secondline = text.split("\n")[1]
     temp = secondline.split(" ")[9]
     temperature  = float(temp[2:])
     temperature = temperature/1000
     mystr = str(temperature)
     y =  mystr.replace(",",".")
     x = datetime.datetime.now().time() 
return  ReturnValue(x, y)

您没有正确缩进return语句以及函数foo中的第一行。

SyntaxError：'return'外部函数？
