检查重新格式化Python代码的工具不变

Question

Is there a tool, or method, to check that given two python files, they will parse identically?

The specific use case I'm thinking of: I'm currently making a large number of code changes to improve readability. Many of them (reindenting, removing spaces around = in keyword arguments) introduce no changes to the meaning of the code (unless done incorrectly) whatsoever. I would be able to make such changes more quickly if I could quickly verify that the new code was identical to the old, as far as Python is concerned.

也许使用dis.dis()转储指令并比较或校验和输出？
