<｜begin▁of▁sentence｜>### Instruction:
Given a graph which you can read from littleballoffur3.sparse6, can you use MetropolisHastingsRandomWalkSampler to sample a connected subgraph with a specified number of nodes?
### Response:
import networkx as nx
from littleballoffur import MetropolisHastingsRandomWalkSampler
G = nx.read_sparse6('littleballoffur3.sparse6')
sampler = MetropolisHastingsRandomWalkSampler(number_of_nodes=10, seed=42, alpha=1.0)
sampler_G = sampler.sample(G)
print(sampler_G.edges(), sampler_G.nodes());
