为什么我的变量没有用python

Question

在寻求帮助时，我无法弄清为什么变量没有被带入cloud4rpi流。他们打印出并写入文件就好了，而我正在同一循环中执行cloud4rpi。

#!/usr/bin/env python
#
# GrovePi Project for a Plant monitoring project.
#   *   Reads the data from moisture, light, temperature and humidity sensor 
#       and takes pictures from the Pi camera periodically and logs them
#   *   Sensor Connections on the GrovePi:
#           -> Grove Moisture sensor    - Port A0
#           -> Grove light sensor       - I2C-1
#           -> Grove Temp sensor        - I2C-2

我是如此接近，只是无法获得将值升至cloud4rpi。尝试过字符串和数字。 任何帮助将不胜感激，我不是一个优秀的程序员，所以它有点超出我的头脑了。
