<｜begin▁of▁sentence｜>### Instruction:
Imagine we're working on an information system that maps out relationships and interactions within a business network. In the process of modeling this using a network graph, we've created a MultiDiGraph data structure with nodes representing 'Department A' and 'Department B'. This graph has incorporated multiple interactions between these two departments, as well as self-referencing interactions within 'Department A'.

As part of the system's refinement and in preparation for presenting this model to the stakeholders for a clearer understanding of the departmental interactions, we would like to simplify the graph. Specifically, we aim to consolidate the multiple direct interactions between 'Department A' and 'Department B' into a single representative connection and simultaneously eliminate any self-interacting loops within 'Department A' for our presentation layer.

For the system to generate this streamlined view, could you illustrate how we might employ the method 'hide_multidiedges' in order to transform our original MultiDiGraph? This should result in a graph that presents only unique connections between different departments while excluding the repetitive interactions and intradepartmental communications. The manipulation of the data is intended purely for visualization purposes and should not alter the underlying data structure used for analysis.

This graph transformation will then be used to better communicate the streamlined process flows and interdepartmental relationships during our upcoming system review meeting. Your guidance will be crucial in enhancing the clarity and effectiveness of our presentation materials.
### Response:
import networkx as nx

# Create a MultiDiGraph with self loops and parallel edges
G = nx.MultiDiGraph()
G.add_edge('A', 'B')
G.add_edge('A', 'B')  # parallel edge
G.add_edge('A', 'A')  # self loop

# Before hiding multi-edges
print(f'Original edges: {list(G.edges())}')

# Hide multi-edges
H = nx.DiGraph(G)
H = nx.hide_multidiedges(H)

# After hiding multi-edges
print(f'Edges after hiding multi-edges: {list(H.edges())}')
