Which data structure results from running the following Python code?

The outermost data structure is a Python dictionary because its contents are enclosed in braces and organized as key-value pairs. Examples include bd: bd1, name: 182324589678, and pv1: pv1. The json.load() function reads the JSON document from the opened file and converts each JSON object into a Python dictionary. The value associated with the app key is a nested dictionary. Inside that dictionary, epgs maps to a list containing three additional dictionaries. Although the overall structure contains a list, its outermost object—and therefore the value assigned to var1—is a dictionary. A set also uses braces in Python but contains individual unordered values rather than colon-separated key-value pairs. Tuples use parentheses, while lists use square brackets.
