This should get you started.

import json

dic = {'key1': 'value1',
       'key2': 'value2',
       'key3': 'value3',
       'key4': 'value4',
       'key5': 'value5',
       }

with open("datafile.txt", "w") as outfile:
    # convert dict to json format, write to file
    outfile.write(json.dumps(dic))


with open("datafile.txt", "r") as infile:
    # read from file, convert json format to dict
    new_dic = json.loads(infile.read())

print(new_dic)
print(dic == new_dic)
