Hi, I am learning python to reslove issue,which make happy:)
But, i am facing an interesting question.I have no idea to deal with it. The text i will working as follow: ```text [PATCH] perf tools: Fix copyfile_offset update of output offset We need to increase output offset in each iteration, not decrease it as we currently do. I guess we were lucky to finish in most cases in first iteration, so the bug never showed. However it shows a lot when working with big (~4GB) size data.

I have crawled the text with python and want to remove strings from *diff --git*, because reading the git commit above, i have a shape in head. I have tried split(), replace(), but i have no idea to deal with it. I will appericate if you have any idea.
