UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-4: ordinal not in range(128)

先说解决方法：

import sysreload(sys)sys.setdefaultencoding('utf-8')

即在代码文件开始先导入sys包，然后在代码里调用修改默认编码方式的方法setdefaultencoding
下面解释原因：这个问题是由于Unicode编码与ASCII编码的不兼容造成的。
首先在不添加以上代码的前提下先查看python调用的默认编码：

import sysprint sys.getdefaultencoding()

通常都是ascii，由此Python自然调用ascii编码解码程序去处理字符流，当字符流不属于ascii范围内，就会抛出异常（ordinal not in range(128)）。所以解决方法就是修改默认编码，需要注意的是需要先调用reload方法。

reload(sys)sys.setdefaultencoding('utf-8')
