 Python doesn't support "true" concurrency due to the [Global Interpreter Lock][GIL].
 While work is ongoing to create support for [free-threading in Python][free-threading], it is still experimental.
 Current standard library solutions such as [multiprocessing][multiprocessing-module] and [threading][threading-module] are difficult to implement with the current track tooling.  
 
 
 As a result, the concurrency requirement has been set aside for this exercise. 
-Account operations are sequential on a single thread, and no concurrency or "race condition" tests are run.

-*NOTE*: The description above mentions mathematical sets, but also that a Pythagorean Triplet {a, b, c} _must_ be ordered such that a < b < c (ascending order). This makes Python's `set` type unsuited to this exercise, since it is an inherently unordered container. Therefore please return a list of lists instead (i.e. `[[a, b, c]]`). You can generate the triplets themselves in whatever order you would like, as the enclosing list's order will be ignored in the tests.
