<｜begin▁of▁sentence｜>### Instruction:
Given a path graph with 4 nodes, can you write the graph to a file in sparse6 format using NetworkX and then read back and print the contents of the file?
### Response:
import networkx as nx
import tempfile

# Create a graph
G = nx.path_graph(4)

# Write to a sparse6 file
with tempfile.NamedTemporaryFile(delete=False) as f:
    nx.write_sparse6(G, f.name)
    f.seek(0)
    print(f.read())
    # Output will be in the format of a sparse6 string representation
