Question

I want to write a dictionary into a file. The code is:

 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

As you see, I traverse the dictionary of store_dic and write in the file at the same time.
Because I will call this code every 6 seconds, are there any ways to improve this?

Thank you.

Just use json module.

import json

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

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