<｜begin▁of▁sentence｜>### Instruction:
Given a networkx erdos_renyi_graph with params n=500, p=0.2, can you use DiffusionSampler to sample a subgraph of 150 nodes using a diffusion process and check the number of nodes in the sampled graph?
### Response:
import networkx as nx
from littleballoffur import DiffusionSampler

G = nx.gnp_random_graph(n=500, p=0.2)

sampler = DiffusionSampler(number_of_nodes=150, seed=10)

sampler_G = sampler.sample(G)

result = nx.number_of_nodes(sampler_G)

print(result)
