Dynamicaly import specific dict from file

Question

I have a file containing lots of python dict. I want to load some of those dict as requested by the user. How cant I do that ?

my_dicts_file.py:

A = { 'value_a': 0,
      'value_b':'aa'}

B = { 'value_a': 10,
      'value_b':'bb',
      'value_c':'Nd'}

....
....

Z = { 'value_4': 50,
      'value_t':'0d'}

The following code does not work

for i in ['A','C']:
    from my_dicts_file import i

I don't want to load all the dicts if possible with

from my_dicts_file import *

I think that is impossible. With `from A import B` you can import only one method or class. Not a variable — Valeriy, Oct 20 '16 at 12:05

You can pickle the variables and then load when you need them. To do that you can use Python's pickle module

I'm not sure if it can do direct import like that, but I create some dummy example here.

import imp
my_dict = type('lambdaobject', (object, ), {})()
for i in ['A', 'C']:
    src = imp.load_source(i, 'my_dicts_file.py')
    setattr(mydict, i, getattr(src, i))

say if you're wanted to print variable A, you just

print my_dict.A
