Before pycharm recurring error codes

No matter how modified files encoded content, it still appears the same issue, at a function in New .py files, and can be compiled successfully;

Is it once suspected, pycharm compile time should clear the cache;

Later I thought it was pcy look for a long time, finally found, before modifying the file name, and did not modify successfully, the file name with python keyword repeated;

Such acts by their own stupid to cry;
