I checked all the calls made to `_interpolate_some`, and each call seems to pass the `list` type argument in the 4th position, but then function calling a `find` method on that 4th `list` type argument.  Which is causing above error.

Hi! It's very hard to work out what the problem might be here if you don't show us the code that caused the error. Also, this site is for reporting bugs in the Python programming language itself, and this doesn't look like a bug in Python to me. You might be better off posting this question on Discuss (https://discuss.python.org/c/users/7), reddit, or StackOverflow.

Having said all that, it looks like you're passing in a list where a string is expected — `list` objects don't have a `find` method (https://docs.python.org/3/tutorial/datastructures.html), but `str` objects do (https://docs.python.org/3/library/stdtypes.html#str.find).

Good luck solving your problem :)

Also note that Python 3.6 only receives security updates now.  Does your problem still happen with a current version?
