Multiple keys per value

Question

Is it possible to assign multiple keys per value in a Python dictionary. One possible solution is to assign value to each key:

dict = {\'k1\':\'v1\', \'k2\':         


        

Answer 1

I was able to achieve similar functionality using pandas MultiIndex, although in my case the values are scalars:

>>> import numpy
>>> import pandas
>>> keys = [numpy.array(['a', 'b', 'c']), numpy.array([1, 2, 3])]
>>> df = pandas.DataFrame(['val1', 'val2', 'val3'], index=keys)
>>> df.index.names = ['str', 'int']
>>> df.xs('b', axis=0, level='str')
        0
int      
2    val2

>>> df.xs(3, axis=0, level='int')
        0
str      
c    val3
