<｜begin▁of▁sentence｜>### Instruction:
Given a path graph of five nodes created with NetworkX, use the dfs_tree function to construct a depth-first-search tree with 0 as the source node and a depth limit of 2. What are the edges of the resulting tree?
### Response:
import networkx as nx

# Create a NetworkX graph
G = nx.path_graph(5)

# Use dfs_tree to obtain a tree starting at source node 0
T = nx.dfs_tree(G, source=0, depth_limit=2)

# Print the edges of the tree
print(list(T.edges()))

# Output:
# [(0, 1), (1, 2)]
