Работа с “глубокими” словарями в Python 3.6.*

Столкнулся с проблемой поиска по "глубокому" словарю (много вложенных друг в друга словарей). Словарь получается из .json файла и содержит в себе вложенные словари схожей структуры. У меня задача получить все значения определенных полей словарей на одном из нижних уровней, сейчас делаю рекурсивно, но возможно кто-нибудь сталкивался с подобной проблемой, и есть какие-нибудь модули по типу beautifulsoup для решения подобных задач.

Expected result of FillChar is just plain sequence of just repeating 8-bit characters in a given memory buffer. Expected result of StringOfChar is the same, but the result is stored inside a string type.

The StringOfChar and FillChar dont work properly they return a string of different characters, although in a repeating pattern not just a sequence of the same character as they should. Here is the minimal code enough to demonstrate the issue. Please note that the length of the sequence should be at least ...
