本人在使用 groovy 爬取了全国 3000+ 城市的历史天气之后，需要把每个城市的历史天气都绘制一张 Time Series 表格，用来反映各地的最高温最低温温差的变化曲线。这里遇到了一个问题，每次 plotly 绘制完图标总会调起系统浏览器打开呈现，一旦我批量生成 N 多张表格时，电脑就会卡死了。在使用中文作为文件名的时候遇到了一个错误，这个错误刚好能巧妙解决这个问题。在不同编码格式的字符拼接时文件路径时，会报错，报错内容如下：

'ascii' codec can't encode characters in position 69-70: ordinal not in range(128)

然后程序停止运行，但是文件已经生成了。在做了异常处理后，刚好能满足需求。关于 python2.7 的编码问题，并不是很了解为什么出这个错。

python 部分的代码如下：

#!/usr/bin/python
# coding=utf-8
