def function_that_returns_a_number_out_of_a_string(string, cache=):
return cache.index(string) if string in cache else
(cache.append(string) or len(cache)-1)
That will work perfectly, as long as you don't care how long the
numbers end up, and as long as you have a single Python script doing
the work, and as long as you make sure you save and load that cache
any time you shut down the script, and so on.
It will also, and rightly, be decried as a bad idea. But hey, you did
specify that it be one line of code. For your real job, USE A DATABASE
