<｜begin▁of▁sentence｜>### Instruction:
As a Training Coordinator, you have been asked to plan and coordinate a training program in which participants will learn about exploring and sampling subgraphs in networkx. The program will include a practical scenario where participants will use the DepthFirstSearchSampler method to sample a subgraph containing 50 nodes from an Erdos-Renyi graph with n=200 and p=0.15. Please integrate the relevant data and describe the steps the participants need to take to complete the practical scenario.
### Response:
import networkx as nx
from littleballoffur import DepthFirstSearchSampler

G = nx.gnp_random_graph(n=200, p=0.15)

sampler = DepthFirstSearchSampler(50, seed=10)

sampler_G = sampler.sample(G)

print(sampler_G.nodes())
