Data structure question

[Joseph L. Casale]

I have a need for a script to hold several tuples with three values, two text
strings and a lambda. I need to index the tuple based on either of the two
strings. Normally a database would be ideal but for a self-contained script
that's a bit much.

Before I re-invent the wheel, are there any built-in structures that allow for
this type of use case?

Thanks,

Sounds like you should create a dictionary, and enter each tuple twice, once with each string as a key:

d = {}
for t in the_tuples:
d[t[0]] = d[t[1]] = t
