我挑食时是否需要创建文件？ [英] Do I need to create files when I pickle?

问题描述

我一直有这个问题。当我们腌制某些东西时，我们会将腌制数据存入的文件，我们是否手动创建这些文件？



当我们编写如下代码时：

I have been having this problem for a while.When we pickle something, the files that we will save the pickled data into, do we create those manually?

When we write a code such as the following:

save_documents = open("pickled_algos/documents.pickle","wb")
pickle.dump(documents, save_documents)
save_documents.close()

我是否需要创建pickled_algos / documents.pickle文件？我究竟需要做什么？



我的尝试：



我试过用这个名字创建一个文件但是卡住了

Do i need to create the pickled_algos/documents.pickle file? what exactly do I need to do?

What I have tried:

I have tried creating a file in that name but got stuck

推荐答案

如果你正在阅读文档，你可以看到两者都有一个选项 - 写作将结果直接或以二进制字符串形式返回并以任何方式使用它...

您的代码示例直接将对象'documents'写入文件'save_documents' ...

If you are reading the documentation, you can see that there is an option for both - writing the result to a file directly or getting it back as binary string and use it any way you like...
Your code-sample do direct write of the object 'documents' to the file 'save_documents'...
