@LanjiaoGong 如果用iteritems遍历并修改字典,会报错;items会根据原来的字典重新生成一个列表,不影响。
btw, 我在linkedin上关注你了。

嗯嗯 我也关注你了。
就是这段代码:
for key, val in inner_dict.items():
if isinstance(val, dict):
compress_tree(val)
else:
inner_dict.pop(key)
inner_dict.update(copy_dict)
我是用的items不知道为什么,执行的时候还是出错:
RuntimeError:dictionary changed size during iteration.

@LanjiaoGong http://stackoverflow.com/questions/11941817/how-to-avoid-runtimeerror-dictionary-changed-size-during-iteration-error 这个代码在Py2.7下是可以正常运行的,py3可能不兼容,可以参考一下这个链接。
