我已经浏览了Python文档提供的信息,但我还是有点困惑。有人可以发布一个示例代码,编写一个新文件,然后使用pickle将字典转储到其中吗?

# Save a dictionary into a pickle file.
import pickle

favorite_color = {"lion": "yellow", "kitty": "red"}  # create a dictionary
pickle.dump(favorite_color, open("save.p", "wb"))  # save it into a file named save.p

# -------------------------------------------------------------
# Load the dictionary back from the pickle file.
import pickle

favorite_color = pickle.load(open("save.p", "rb"))
# favorite_color is now {"lion": "yellow", "kitty": "red"}

如果你只是想把字典存储在一个文件中,可以像这样使用pickle

import pickle

a = {'hello': 'world'}

with open('filename.pickle', 'wb') as handle:
    pickle.dump(a, handle)

with open('filename.pickle', 'rb') as handle:
    b = pickle.load(handle)

如果您想在多个文件中保存和恢复多个字典 缓存和存储更复杂的数据, 使用anycache。 泡菜周围的其他东西它都有

from anycache import anycache

@anycache(cachedir='path/to/files')
def myfunc(hello):
    return {'hello', hello}

的参数来存储不同的myfunc结果 不同的文件在cachedir并重新加载它们。

import pickle

dictobj = {'Jack' : 123, 'John' : 456}

filename = "/foldername/filestore"

fileobj = open(filename, 'wb')

pickle.dump(dictobj, fileobj)

fileobj.close()

将Python数据(例如字典)转储到pickle文件的简单方法。

import pickle

your_dictionary = {}

pickle.dump(your_dictionary, open('pickle_file_name.p', 'wb'))

我发现它更容易。

pd.to_pickle(object_to_save,'/temp/saved_pkl.pickle' )
