<｜begin▁of▁sentence｜>### Instruction:
Given a graph read from littleballoffur8.sparse6, can you use MetropolisHastingsRandomWalkSampler to sample a connected subgraph containing 10 nodes with a rejection constraint exponent of 0.5?
### Response:
import networkx as nx
from littleballoffur import MetropolisHastingsRandomWalkSampler
G = nx.read_sparse6('littleballoffur8.sparse6')
sampler = MetropolisHastingsRandomWalkSampler(number_of_nodes=10, seed=42, alpha=0.5)
sampled_graph = sampler.sample(G)
print(sampled_graph.edges(), sampled_graph.nodes())
