Convert a python dict to a string and back

Question

I am writing a program that stores data in a dictionary object, but this data needs to be saved at some point during the program execution and loaded back into the dictionar

Answer 1

I use yaml for that if needs to be readable (neither JSON nor XML are that IMHO), or if reading is not necessary I use pickle.

Write

from pickle import dumps, loads
x = dict(a=1, b=2)
y = dict(c = x, z=3)
res = dumps(y)
open('/var/tmp/dump.txt', 'w').write(res)

Read back

from pickle import dumps, loads
rev = loads(open('/var/tmp/dump.txt').read())
print rev
