Multikey Multivalue Non Deterministic python dictionary

Question

There is already a multi key dict in python and also a multivalued dict. I needed a python dictionary which is both:

example:

# probabilistically fetch a         


        

Answer 1

If it is possible to change the data structure, it would be simpler to have a function returning the data you need. This will be completely flexible and could accommodate any kind of data, should you need to change them later.

import random

def myfunc(*args):
    if 'red' in args:
        return 'blue'
    elif 'green' in args or 'violet' in args:
        return 'violet'
    else:
        r = random.random()
        if 0 < r < 0.2:
            return 'blue'
        else:
            return 'green'

print(myfunc('green', 'blue'))
print(myfunc('yellow'))

output (the second line obviously changes):

violet
blue
