<｜begin▁of▁sentence｜>### Instruction:
How can the midpoint position and alignment of labels for the edges in an igraph generated graph be determined when visualizing with Plotly in Python?
### Response:
import igraph as ig
import plotly.graph_objs as go
from igraph.drawing import PlotlyEdgeDrawer

def draw_graph_with_edge_labels(graph):
    layout = graph.layout('kk')  # Kamada-Kawai layout
    plotly_drawer = PlotlyEdgeDrawer(graph, layout)
    edge_trace = go.Scatter(
        x=[], y=[],
        line=dict(width=0.5, color='#888'),
        hoverinfo='none',
        mode='lines')

    for edge in graph.es:
        x0, y0 = layout[edge.source]
        x1, y1 = layout[edge.target]
        edge_trace['x'] += tuple([x0, x1, None])
        edge_trace['y'] += tuple([y0, y1, None])
        # Get edge label position
        label_pos, alignment = plotly_drawer.get_label_position(edge)
        # Here you can add code to display the edge label using label_pos

    fig = go.Figure(data=[edge_trace], layout=go.Layout(
        title='<br>Network graph made with Python',
        titlefont_size=16,
        showlegend=False,
        hovermode='closest',
        margin=dict(b=20,l=5,r=5,t=40),
        annotations=[ dict(
            text='Edge labels can be placed using label positions',
            showarrow=False,
            xref='paper', yref='paper',
            x=0.005, y=-0.002 ) ],
        xaxis=dict(showgrid=False, zeroline=False, showticklabels=False),
        yaxis=dict(showgrid=False, zeroline=False, showticklabels=False))
    )
    return fig

# Sample usage
# Create a graph
sample_graph = ig.Graph([(0, 1), (1, 2), (2, 3), (3, 0)])
# Draw the graph
fig = draw_graph_with_edge_labels(sample_graph)
fig.show()
