Is it possible to call separate dictionaries using a user input variable in Python 3? Any help much appreciated.

Apologies in advance if this is a school boy error. I am developing a Python 3 script to do a series of calculations using values in a dictionary. This works fine for a single dictionary but ideally I would like to be able to call separate variants of this dictionary using a user input variable. I have tried to call the separate dictionaries using the variable as the dictionary name e.g.: print(variable[X]) This however results in an error. is it possible to use dictionaries in this way?

Yes, you can do such a thing, although that's probably not how you should approach this problem. Better to make a list of dictionaries and just call them by index. It's a lot easier to keep track, especially if there are many of them. But anyway... https://code.sololearn.com/cULv3uY3OlZ0/?ref=app Just input 'a' or 'b'

roughly said you need a kind of dictionary factory and your approach seems to be good. dict1 = {.....} dict2 ={.........} dict3 = {...} if input == 1: variant = dict1 elif input ==2: variant = dict2 variant is a dictionary

inp = int(input("input:")) dicts = [{....,},{...},{....,}] thedict = dicts[inp]
