Python - 将多个 Pickle 对象加载到单个字典中 [英] Python - Load multiple Pickle objects into a single dictionary

问题描述

所以我的问题是...我有多个 Pickle 对象文件(它们是 Pickled Dictionaries)，我想将它们全部加载，但基本上将每个字典合并到一个更大的字典中.

So my problem is this... I have multiple Pickle object files (which are Pickled Dictionaries) and I want to load them all, but essentially merge each dictionary into a single larger dictionary.

例如

我有 pickle_file1 和 pickle_file2 都包含字典.我想将 pickle_file1 和 pickle_file2 的内容加载到 my_dict_final 中.

I have pickle_file1 and pickle_file2 both contain dictionaries. I would like the contents of pickle_file1 and pickle_file2 loaded into my_dict_final.

编辑根据要求，这是我目前所拥有的:

EDIT As per request here is what i have so far:

for pkl_file in pkl_file_list:
    pickle_in = open(pkl_file,'rb')
    my_dict = pickle.load(pickle_in)
    pickle_in.close()

本质上，它是有效的，但只是覆盖了 my_dict 的内容，而不是附加每个泡菜对象.

In essence, it works, but just overwrites the contents of my_dict rather than append each pickle object.

预先感谢您的帮助.

推荐答案

my_dict_final = {}  # Create an empty dictionary
with open('pickle_file1', 'rb') as f:
    my_dict_final.update(pickle.load(f))   # Update contents of file1 to the dictionary
with open('pickle_file2', 'rb') as f:
    my_dict_final.update(pickle.load(f))   # Update contents of file2 to the dictionary
print my_dict_final
