在python中将字符串转换为OrderedDict [英] string to OrderedDict conversion in python

问题描述

我通过导入集合创建了python命令字典，并将其存储在名为"filename.txt"的文件中.文件内容看起来像

i have created a python Ordered Dictionary by importing collections and stored it in a file named 'filename.txt'. the file content looks like

OrderedDict([(7, 0), (6, 1), (5, 2), (4, 3)])

我需要使用另一个程序中的OrderedDict.我这样做

i need to make use of this OrderedDict from another program. i do it as

myfile = open('filename.txt','r')
mydict = myfile.read()

我需要获取类型为的'mydict'

i need to get 'mydict' as of Type

<class 'collections.OrderedDict'>

但是在这里，它的类型为'str'.
python中有什么方法可以将字符串类型转换为OrderedDict类型?使用python 2.7

but here, it comes out to be of type 'str'.
is there any way in python to convert a string type to OrderedDict type? using python 2.7

推荐答案

您可以使用腌制

import cPickle as pickle

# store:
with open("filename.pickle", "w") as fp:
    pickle.dump(ordered_dict, fp)

# read:
with open("filename.pickle") as fp:
    ordered_dict = pickle.load(fp)

type(ordered_dict) # <class 'collections.OrderedDict'>
