python filepath = r'f:\origin-pytest\exc' 使用双反斜杠:每个反斜杠前再加一个反斜杠来“转义”它本身,这样Python就会将其视为普通字符而非转义字符的开始。 python filepath = 'f:\\origin-pytest\\exc' 使用正斜杠:在Windows系统中,文件路径也可以使用正斜杠(/)来分隔目录,这样就不需要担心转义序列的...
python执行代码的时候会在__pycache__目录下生成对应的pyc文件, 就是python字节码文件, 这样后面执行的时候只需要看下时间戳是否能对上, 对上的话, 就没必要再转字节码了. 而这个warning是转字节码的时候告警的, 而不是执行阶段告警的. 直接执行的话, 不会生成pyc字节码, 因为Python会认为你只是偶尔执行, 没...
