Convert a python dict to a string and back

The json module is a good solution here. It has the advantages over pickle that it only produces plain text output, and is cross-platform and cross-version.

import json
json.dumps(dict)

If your dictionary isn't too big maybe str + eval can do the work:

dict1 = {'one':1, 'two':2, 'three': {'three.1': 3.1, 'three.2': 3.2 }}
str1 = str(dict1)

dict2 = eval(str1)

print(dict1 == dict2)

You can use ast.literal_eval instead of eval for additional security if the source is untrusted.

I use json:

import json

# convert to string
input = json.dumps({'id': id })

# load to dict
my_dict = json.loads(input)
