<｜begin▁of▁sentence｜>### Instruction:
As a photojournalist covering a city's annual technology conference, you have taken numerous photos of the attendees mingling at various booths and conference sessions. While documenting the networking aspect of the event, you come across a group of 100 tech enthusiasts engaging with each other in a diverse manner.

By utilizing specialized software called MetropolisHastingsRandomWalkSampler, you intend to select a random subset of 20 individuals from this group to focus on. Once this subset is identified, you plan to analyze and calculate the communicability levels between all pairs of the 20 selected individuals within the network, shedding light on the information flow and connections among them.
### Response:
import networkx as nx
from littleballoffur import MetropolisHastingsRandomWalkSampler

G = nx.gnp_random_graph(n=100, p=0.3)

sampler = MetropolisHastingsRandomWalkSampler(20, seed=42)

sampler_G = sampler.sample(G)

result = nx.communicability(sampler_G)

print(result)
<|EOT|>
