试图在python中腌制列表 [英] Trying to pickle a list in python

问题描述

按照许多资料提供的确切方法，尝试使用pickle在python中保存整数列表，但我仍然遇到相同的错误.这是简化版:

Trying to save a list of integers in python using pickle, following the exact method given to me by many sources, and I'm still encountering the same error. Here's the simplified version:

import pickle
a=[0,4,8,[3,5]]
with open(blah.pickle, 'wb') as b:
    pickle.dump(a,b)

我总是收到错误消息:

NameError: name 'blah' is not defined

怎么了?

推荐答案

您需要将其设置为字符串:

You need to make it a string:

import pickle
a=[0,4,8,[3,5]]
with open('blah.pickle', 'wb') as b:
    pickle.dump(a,b)

没有引号，Python正在寻找名为blah的变量，并尝试获取该对象的pickle属性.由于您从未将blah定义为变量，因此得到了NameError.

Without the quotes, Python is looking for the variable called blah and trying to get the pickle attribute of that object. Since you have never defined blah as a variable, you get a NameError.
