我有一个 python 脚本(脚本 1)，它生成一个大的 python 字典.该词典必须由另一个脚本(脚本 2)读取.任何人都可以建议我编写由脚本 1 生成的 Python 字典并由脚本 2 读取的最佳方法.过去我曾使用 cPickle 编写和阅读如此大的字典.有没有更好的方法来做到这一点?

Could any one suggest me the best way to write the python dictionary generated by script 1 and to be read by script 2. In past I have used cPickle to write and read such large dictionaries. Is there a beter way to do this?

推荐答案

shelve 将让您分别访问每个项目，而不是要求您每次都序列化和反序列化整个字典.

shelve will give you access to each item separately, instead of requiring you to serialize and deserialize the entire dictionary each time.
