关于字典写入文件

Question

我想将字典写入文件。代码是：

 fs = open( store_file , "w" )
 for k in store_dic:
     temp_line = k + " " + store_dic[k] + "\n"
     fs.write( temp_line )
     logger.info( "store_record " + store_file + " " + temp_line[:-1] )
     fs.close

如您所见，我遍历store_dic字典并同时写入文件。 还有其他方法来改善这个吗？因为我会每6秒调用一次此代码。

谢谢。

Answer 1

使用pickle

将Python dict保存到文件中

import pickle

# write python dict to a file
mydict = {'a': 1, 'b': 2, 'c': 3}
output = open('myfile.pkl', 'wb')
pickle.dump(mydict, output)
output.close()

Answer 2

只需使用json模块。

import json

store_dic = { "key1": "value1", "key2": "value2" }

with fs as open(store_file, "w"):
    json.dump(store_dic, fs)
