If the values are integers but I usually draw lists outside the box, strings, floats just to keep the diagram te. Python dictionaries are called associative arrays or hash tables in other languages. Python dictionary is a container of key- value pairs. If any module is being used which has a C code component that uses the simplified API for access to the Global Interpreter Lock ( GIL) for Python extension modules, then the interpreter name must be forcibly set to be ' main_ interpreter'.
