    for key in dic.keys():
        for key2 in dic[key]:
            dic2[key + ' ' + str(key2)] = dic[key][key2]

I gave the code a cursory look, and this part has drawn my attention. Iterating over dict.keys() maybe was acceptable in 2.2 or 2.3 - but for years it has been considered un-Pythonic, since iteration over dictionary already yields keys

Moreover, you can iterate over items

for key, dic2 in dic.items:
    for key2, value2 in dic2.items()
        dic2[key + ' ' + str(key2)] = value

Actually, a lot of things in your code look off - converting to dict, and then working hard to rearrange - but I am not up to the task now
