Is there any function in Networkx that directly generates adjacency list from a table of nodes

Suppose that an Undirected graph neighboring nodes are given in a txt file as below

1 2
1 3
1 4
1 5
2 5
2 6
3 4

can I generate an adjacency matrix by a single function in networkx as below

[0 1 1 1 1 0 ]
[1 0 0 0 1 0 ]
[1 0 0 1 0 0 ]   
[1 0 1 0 0 0 ]
[1 1 0 0 0 0 ]
[0 0 0 0 0 1 ]

It is not really one function, but you can read edges from file and then create adjacency matrix like this:

import networkx as nx

G = nx.read_edgelist('list.txt')
A = nx.adjacency_matrix(G)

which gives

matrix([[ 0.,  1.,  1.,  1.,  1.,  0.],
        [ 1.,  0.,  0.,  0.,  1.,  0.],
        [ 1.,  0.,  0.,  1.,  0.,  1.],
        [ 1.,  0.,  1.,  0.,  0.,  0.],
        [ 1.,  1.,  0.,  0.,  0.,  0.],
        [ 0.,  0.,  1.,  0.,  0.,  0.]])
