[英]python pickle gives “AttributeError: 'str' object has no attribute 'write'”
When I try to pickle something, I get an AttributeError: 'str' object has no attribute 'write'
当我尝试腌制某些东西时,我得到一个AttributeError: 'str' object has no attribute 'write'
An example: 一个例子:
import pickle
pickle.dump({"a dict":True},"a-file.pickle")
produces: 生产:
...
AttributeError: 'str' object has no attribute 'write'
What's wrong? 怎么了?
It's a trivial mistake: pickle.dump(obj,file)
takes a file
object, not a file name. 这是一个微不足道的错误: pickle.dump(obj,file)
接受一个file
对象,而不是文件名。
What I need is something like: 我需要的是:
with open("a-file.pickle",'wb') as f:
pickle.dump({"a dict":True},f)
