问题 I saved a python dictionary in this way: import cPickle as pickle pickle.dump(dictname, open("filename.pkl", "wb")) And I load it in another script in this way: dictname = pickle.load(open("filename.pkl", "rb")) How is it possible to close the file after this? 回答1: It's better to use a with statement instead, which closes the file when the statement ends, even if an exception occurs: with open("filename.pkl", "wb") as f: pickle.dump(dictname, f) ... with open("filename.pkl", "rb") as f:
