Python Program For Graph Deletion Operation | Delete Node | Adjacency Matrix | Data Structure

In this Python Programming video tutorial you will write a function to delete given node in the given graph in detail.

Data structure is a way of storing and organising the data so that it can be accessed effectively.
Graph is a non linear data structure consisting of nodes and edges.

format function:

add_node function:

add_edge function:

def delete(v1):
global count
o=node.index(v1)
for i in range(count):
for j in range(count):
if o==j:
graph[i].pop(j)
count=count-1
graph.remove(graph[o])
node.remove(v1)

from last 3 days I watched your tutorials on DS from video 1 and now I am at 25th video.. today I feel like yesturday it was 23/68 and today 25/70 .. hehehe YOUR VIDEO LECTURES ARE AWESOME thanks mam..

hello mam
probably you have forgotten to write a method for deletion of a row of graph
def delete_node(v):
global node_count
if v not in node:
print('v is not present in graph')
else:
index1=node.index(v)
node_count=node_count-1
node.remove(v)

for i in graph:
i.pop(index1)

thank you for your tutorial🙂

list1=['a', 'b', 'c', 'd']
for i in list1:
add_node(i)
add_edge('a', 'b')
delete_node('d')


hello mam, Can you pls tell me y its showing POP INDEX OUT OF OF RANGE error when I use for loop for adding nodes to the graph

Ma'am you never made video on project
