Re: [Python-Dev] where is the python "import" implemented

        in this situation, I can not find the source code how python implement it. I test a wrong format pyc, and got a error "ImportError: bad magic number"，and I search "bad magic number" in the source code,  I find it is in importlib/_bootstrap.py(line 815)，but when I modify this error info(eg: test bad magic) and run again, nothing is changed. It seems that the file is not the correct position.

This is the right position. When you change _bootstrap.py, you need to run "make" again, to freeze the modified _bootstrap.py. Regards, Martin
