How to show label outside the node in networkx graph

Question

How to show label above the node in networkx

Answer 1

Here a complete graph is drawn with 4 nodes then pos is used to get the x and y coordinates of the nodes in form of dictionary. Then pos_higher is used to manipulate the position of labels. A dictionary for labels is made and
nx.draw_networkx_labels(G, pos_higher,labels) is used to plot labels on the previous drawn graph.
Example:

import networkx as nx
G=nx.complete_graph(4)
pos=nx.spring_layout(G)
pos_higher = {}

for k, v in pos.items():
if(v[1]>0):
pos_higher[k] = (v[0]-0.1, v[1]+0.1)
else:
pos_higher[k] = (v[0]-0.1, v[1]-0.1)

labels={0:'A',1:'B',2:'C',3:'D'}
nx.draw(G)
nx.draw_networkx_labels(G, pos_higher,labels)
